What can be done to prevent cataracts?

Cataract is an eye disease in which the previously transparent lens of the eye becomes cloudy and affects vision. Patients may feel a layer of white fog obscuring them when they look at objects, making it difficult to see things in front of them, which not only greatly affects quality of life, but also increases the risk of falls or other accidents. While modern medicine has provided an effective set of treatment options to deal with cataracts, preventing cataracts can avoid the inconvenience that patients experience with vision loss and the treatment process. Cataract prevention is an important concept that all ophthalmologists are trying to promote, rather than cure.

How to prevent cataracts

Lens opacity is usually caused by aging eyes, and for senile cataracts, we can prevent them by changing some lifestyle habits.

Avoid ultraviolet and blue light

The proteins in the lens absorb blue light from ultraviolet and visible light, so prolonged exposure to sunlight or prolonged staring at electronic devices can overwork the lens and become cloudy, increasing the risk of cataracts. Therefore, you should wear sunglasses in places where the sun is particularly strong, and at the same time pay attention to let your eyes rest properly and avoid playing with your mobile phone all the time.

Eat a healthy diet

EATING FOODS RICH IN ANTIOXIDANTS, SUCH AS FRUITS, VEGETABLES, AND NUTS, CAN HELP MAINTAIN EYE HEALTH. ADEQUATE INTAKE OF VITAMINS A, C, E, AND OTHER NUTRIENTS CAN ALSO HELP PREVENT CATARACTS. IF YOU ARE AT HIGH RISK OF CATARACTS, IT IS RECOMMENDED THAT YOU GET A DIET PLAN FROM A DIETITIAN OR OPHTHALMOLOGIST TO REDUCE THE INCIDENCE OF CATARACTS.

Control blood sugar levels

Diabetes is an important factor in the development of cataracts. Therefore, keeping blood sugar levels stable is one of the keys to cataract prevention. Do not consume too much sweets such as desserts and milk tea, and plant starches such as flour and rice, which are converted into glucose in the body, should not be consumed excessively. Diabetics are advised to always check their blood sugar regularly and follow their doctor's advice to maintain good blood sugar levels.

Quit smoking

The adverse effects of smoking on eye health have been extensively studied and proven. Smoking causes oxidation of lens cells, which in turn promotes the formation of cataracts. Experiments have shown that smoking can lead to the slow accumulation of heavy metal impurities in the lenses of the eyes, which in turn increases the risk of cataracts. Compared with non-smokers, smokers are 2~3 times more likely to suffer from cataracts. Therefore, quitting smoking is not only good for your health, but also one of the important measures to reduce the risk of cataracts.

Regular eye exams

Regular eye check-ups can help detect any eye problems early, and it is recommended to have 1~2 eye check-ups per year. Early detection of cataracts can make it easier to treat or surge, reducing its impact on vision.

Cataract prevention and eye supplemental food

In addition to the methods mentioned above, we can also slow down the aging of our eyes through some eye-tonifying foods or cataract diet regimens recommended by professional doctors. If you have vision problems or other health problems that require strict dietary control, you should consult a medical professional about eye care and other related issues.

Omega-3 fatty acids

Omega-3 fatty acids are a nutrient that is very important for eye health. They are found in fish, nuts, and vegetable oils. Studies have shown that getting enough omega-3 fatty acids can reduce the risk of cataracts.

VITAMIN E

VITAMIN E IS A POWERFUL ANTIOXIDANT THAT CAN HELP PROTECT THE EYES FROM FREE RADICAL DAMAGE. NUTS, SEEDS, VEGETABLES AND VEGETABLE OILS ARE ALL EYE-TONIC FOODS RICH IN VITAMIN E.

VITAMIN C

VITAMIN C IS AN ANTIOXIDANT RECOMMENDED BY THE AMERICAN OPTOMETRY ASSOCIATION TO HELP PROTECT THE EYES FROM OXIDATIVE DAMAGE AND MAINTAIN THE HEALTH OF THE BLOOD VESSELS IN THE EYES. EYE-TONIC FOODS RICH IN VITAMIN C INCLUDE CITRUS FRUITS, STRAWBERRIES, KIWIFRUIT, CAULIFLOWER, ETC.

Lutein and zeaxanthin

Lutein and zeaxanthin are important nutrients in the eye and can help protect the eyes from UV rays and free radical damage. Intake of eye-tonic foods rich in lutein and zeaxanthin, such as leafy vegetables and corn, can help prevent the occurrence of cataracts.

Keeping an eye eye healthy can prevent not only cataracts, but also other eye diseases, ensuring that you have healthy eyes as you age. If you are unfortunate enough to find cataract symptoms, please make an appointment as soon as possible for a detailed examination. Early detection and timely treatment of cataracts can greatly reduce the difficulty of treatment and maximize vision protection.

Featured Image_Postoperative care of cataract symptoms

How to maintain cataract surgery?

Cataract surgery involves minimally invasive removal of the cloudy lens and implantation of an intraocular lens, which takes about 10 to 30 minutes, but post-cataract surgery care takes up to 1 to 2 months.

In addition to following the doctor's instructions for medication, follow-up visits, and maintaining eye hygiene, how should patients take care of themselves to speed up the recovery time after cataract surgery?

How long do I have to rest after cataract surgery?

Modern cataract surgery is minimally invasive, usually with a 0.2 cm wound. Therefore, exactly how long to rest after cataract surgery depends mainly on the individual's vision recovery.

In general, most patients can see clearly by the second day after cataract surgery. With careful care, vision can be fully restored within 1 week to 1 month after cataract surgery. 

However, we generally recommend that patients after cataract surgery use both eyes normally as soon as possible to speed up the recovery time after cataract surgery. Within a few hours of cataract surgery, if you can see clearly, you can do daily activities such as watching TV, using a computer, eating, and showering.

However, cataract surgery should be followed by careful care, medication as recommended by the doctor, eye cleaning, strenuous exercise and heavy lifting. When the eyes are tired, they should rest properly.

Precautions after cataract surgery

Although cataract surgery is considered a minor surgery, neglect of cataract surgery can lead to intraocular infections and even the risk of blindness. Therefore, proper cataract postoperative maintenance is crucial.

  1. Follow your doctor's instructions to clean your eyes and avoid scratching your eyes.
  2. Avoid collisions, heavy lifting, or strenuous exercise for 1 month after surgery to avoid affecting wound healing or displacement of the intraocular lens.
  3. Avoid bending over to wash your hair for 2 weeks after surgery, and avoid splashing sewage in your eyes when showering.
  4. Wear an eye mask before going to bed.
  5. Wear sunglasses when you go out to prevent light from shining on your eyes.
  6. If you have eye discomfort for a long time, such as severe pain, severe redness and swelling, and vision loss, please treat it immediately.

After-effects of cataract surgery

Cataract surgery is a safe and effective treatment, but there may still be some potential sequelae, but there is no need to worry too much, most of the sequelae of cataract surgery are mild or rare, as long as the vision can be restored with careful care or timely treatment after cataract surgery.

Here are some possible cataract surgery sequelae: 

  • Seeing flashes or shadows: It's fairly common to feel some flashes or shadows within a few hours or days after cataract surgery, but these symptoms go away in a short period of time and don't cause much concern.
  • High intraocular pressure: In some cases, it may cause an increase in intraocular pressure after surgery, which usually disappears after 24 hours. If the intraocular pressure continues to rise, then it may be a problem with residual crystal cortex, inflammation, viscoelastic residue, etc., and you need to seek medical attention immediately.
  • Light sensitivity: After surgery, patients may be more sensitive to bright light, so remember to wear sunglasses when you go out. Over time, the eyes will naturally adapt and the symptoms of light sensitivity will lessen.
  • Posterior capsule opacity: After surgery, some patients may have blurred vision due to the proliferation of epidermal cells in the posterior capsule surrounding the lens. This condition can be corrected with laser treatment, which can improve the symptoms of the eyes.
  • Retinal detachment: If you suddenly see something floating or flashing lights at some point after cataract surgery, making it difficult to see what is in front of you, it is most likely a symptom of retinal detachment, and consult an ophthalmologist immediately for further treatment.
  • Floaters: Some patients find black spots in their eyes after cataract surgery, because their vision was too blurry before cataract surgery to detect the presence of floaters. Floaters are one of the symptoms of eye aging, and if there is no sudden increase in black spots, you can ignore it.

Patients should take proper care of cataract surgery and follow up on time, and seek immediate assistance from an ophthalmologist if there are unusual visual changes after cataract surgery.

Cataract Surgery Frequently Asked Questions

1. How long should I wear sunglasses after cataract surgery?

1 to 2 weeks. After cataract surgery, patients will suddenly feel that the environment becomes brighter and that they can see things clearly, which may cause them to feel uncomfortable with luminosity. Therefore, during the 1st and 2nd weeks after surgery, we recommend that patients wear sunglasses to help their eyes adjust to the light environment.

2. How long after cataract surgery can I wash my own hair?

After the 2nd week or 1 month postoperatively. Although the wound after cataract surgery is small, there is still a risk of infection. When washing your hair yourself, sewage may splash on your eyes, so it is recommended to ask someone else to wash your hair as much as possible within the second week or one month after the surgery, and you must lie flat or on your back when washing your hair to reduce the risk of infection.

3. How Long After Cataract Surgery Can I Touch Water?

1 month. We cannot guarantee that you will not touch water for 1 month after cataract surgery, but what you can do is to avoid contact with water as much as possible. Consider using a face wipe instead of water when washing your face, while eye secretions can be cleaned with cooked water to prevent bacterial infection.

4. How Long After Cataract Surgery Can I Live a Normal Life?

After cataract surgery, it usually takes about 1 month to ensure the stability of the intraocular lens. During this time, as long as you avoid heavy lifting and strenuous exercise, you can basically return to your normal life or return to work the next day after surgery. If possible, it is advisable to take appropriate rest for the first week after surgery. However, patients still need to take good care of their eyes after cataract surgery and follow up on time.

5. How long does it take for vision to recover after cataract surgery?

Generally speaking, the vision will be significantly improved the day after cataract surgery, as long as you pay attention to maintenance after cataract surgery, your vision can be restored to 8~9% within 1 week. If the vision is completely restored and the wound is completely healed, it usually takes about 3 to 4 weeks, and the prescription will be relatively stable at this time.

 6. Will cataract recurrence after surgery?

No. However, about 5% of patients will feel that their vision will gradually become blurred after a period of surgery, because the epidermal cells proliferate in the posterior capsule, causing the posterior capsule to become cloudy, which can be improved with laser treatment. Therefore, when vision changes occur after cataract surgery, you should seek medical attention as soon as possible and treat them in time.

Is surgery necessary to treat cataracts? Intraocular lenses help cataract patients restore their field of vision

According to the World Health Organization, about 39 million people worldwide are blind, of which 51% are caused by cataracts, the leading cause of blindness in the world. The most common cataract is senile cataract, which is usually found to have cataract symptoms in people over 50 years old, while diabetics and deep myopia are more likely to develop cataract symptoms earlier. If the cataract becomes mature, it will bring a series of complications to the patient, such as: glaucoma, uveitis, etc., and even blindness, with serious consequences. Therefore, patients will undergo cataract surgery, treat cataracts with intraocular lenses, and restore clear vision to the eyes through treatment.

What is Cataract?

Cataract is caused by the transparent lens used to focus in the eye becomes cloudy due to old age or disease, and the lens functions like a camera lens, helping the eye to focus accurately, so that the image can be focused on the retina to form a clear image. The lens is made of proteins and has the function of regulating light. When the lens becomes cloudy, the transparency decreases, and light cannot pass through, resulting in decreased vision and cataracts.

What are the symptoms of cataracts?

The symptoms of cataract are relatively easy to identify compared with other eye diseases, such as dry eye, and the most noticeable symptoms generally include reduced reading ability, which is mainly caused by blurred vision, and there will be photophobia problems, patients are also prone to glare at night, or symptoms such as loss of color and contrast resolution. The symptoms of cataract can be subdivided into early cataract symptoms and late cataract symptoms:

Initial cataract symptoms

  • photophobia
  • Monocular diplopia
  • Myopia suddenly spiked geometrically
  • Presbyopia lightened

Late cataract symptoms

  • Vision modeling
  • See things glare
  • The image color becomes dull

Why do I get cataracts?

aging

The main cause of cataract is due to aging of the eyes due to aging, which is also known as "senile cataract", which is caused by the aging and decline of the lens. In medicine, according to the opacity location of the lens, such cataracts are subdivided into three categories: posterior subcapsular opacity, nuclear opacity, and cortical opacity.

Caused by other diseases

Also known as "secondary cataracts", it is caused by surgery, steroid medications, or other health problems such as glaucoma, diabetes, intraocular inflammation, and high myopia.

Caused by trauma

Trauma is also a cause of cataracts. When the eye has been subjected to strong impact, puncture injury, or has been subjected to high heat, chemical burns, etc., the crystal fibers are misaligned, and lesions such as turbidity and hardening may occur. However, some patients do not develop cataracts immediately, but gradually appear later.

Open surgery to treat cataracts is the only way out

At present, open surgery is the only treatment for cataracts. The cataract surgery process involves removing the cloudy lens and implanting an intraocular lens to treat the cataract and improve vision. Generally, cataract surgery is performed under local anesthesia, and doctors use a microscope in the operating room to remove the originally cloudy lens and implant an intraocular lens suitable for cataract patients using ultrasound emulsification technology. Since this is a minimally invasive procedure, the surgical incision will be relatively thin and stitches will not necessarily be required, so the wound recovery time is relatively short. Cataract surgery is safe and complications are uncommon.

However, since everyone's condition and needs are different, and intraocular lenses are not as easy to replace as glasses, you should understand with your doctor before undergoing cataract surgery, and then choose the cataract intraocular lens that suits you.

Before undergoing cataract surgery, the patient decides which intraocular lens to choose for cataracts. Patients can decide which intraocular lens for cataract treatment can bring the best results for patients based on their overall eye health, such as dry eye, corneal astigmatism or macular health, etc., and finally undergo cataract surgery.

At present, there are three main types of intraocular lenses available for cataract surgery:

  • Unifocal intraocular lens

This is a commonly used intraocular lens in cataract patients and is also suitable for all patients. However, this intraocular lens only has a single focal length, and if the single-focal IOL lens implanted with the long-distance viewing function improves farsightedness, it may be necessary to wear reading glasses when performing close activities such as reading or playing sparrows.

  • All-round wide view of intraocular lenses

Lengthen the eye focus, solve the shortcomings of the previous multifocal length intraocular lens that can only see far and close things, and fill the mid-distance vision.

  • Trifocal intraocular lens

This intraocular lens is suitable for cataract and presbyopia patients, it is a multifunctional intraocular lens with far, medium and near full vision, and after surgery, cataract patients will have less dependence on glasses. However, cataract patients may have visual disturbances such as halos and glare after surgery, so patients may need more time to adapt.

In addition, the new generation of continuous intraocular lenses launched in recent years provides a wide continuous field of view from a distance to a reading distance of 33 cm, eliminating the visual gap existing in trifocal technology and other multifocal technologies, allowing patients to experience continuous high-contrast vision from far to near even under low-light conditions, greatly reducing the dependence of cataract patients on glasses. Its UV light filtering technology also helps to reduce glare and halo intensity when driving at night.

Many patients who undergo cataract surgery to treat cataracts will question the duration of the IOL. In fact, current IOLs are made of biocompatible materials such as acrylic or silicone. This means that they do not react with the human body anaphylaxis. For more than 100 years, no cases of aging intraocular lenses affecting vision have been found. So, don't worry about intraocular lens life. IOLs live longer than anyone can live, and rare IOLs change and need to be replaced.

When should I have cataract surgery?

Because when cataracts become mature and worsen, there is a chance to bring a series of complications to patients, such as glaucoma, uveitis, etc., so early treatment should be received cataract surgery. Moreover, under the current medical practice, patients do not need to wait for the symptoms of cataract complications before surgery. Cataract surgery can be considered when vision gradually deteriorates and vision is insufficient to cope with daily work or daily needs. After the patient's vision loss is detected by the nurse, after examination and discussion with the doctor, the decision can be made when to undergo surgery to treat cataracts.

If you wait until the advanced cataract for surgery, the lens will expand or even dissolve, which will bring a series of complications to the patient, such as glaucoma, uveitis, which can lead to irreversible blindness, and advanced cataract surgery is more difficult and vision recovery is slower.

Care after cataract surgery

Patients may have glasses, sunglasses or eye protection for one week after cataract surgery. Do not wipe your eyes with your hands to avoid inflammation of the wound. The eye area can also be gently rubbed with disinfectant cotton or clean paper towels to avoid infection. Normal movement after routine cataract surgery without bed rest. However, complex cases such as trauma and concomitant glaucoma may require restriction of activities.

In terms of diet, abstinence is not required after surgery, but patients should reduce their intake of irritating foods. For people with allergies, foods with high protein content should also be avoided.

Do not swim, do strenuous exercise, and avoid lifting or carrying heavy objects over 30 pounds for one month after surgery. On weekdays, when the head is bent low, be careful to avoid collisions.

Cataract surgery "personalized"

Benefits of cataract surgery personalization

Eyes are like fingerprints, everyone's two eyes are different, so when suffering from cataracts, the situation of each eye will not be exactly the same. Many doctors have tried to find a special intraocular lens for each clinical condition to treat all cataract patients, however, there is no one intraocular lens that is suitable for all patients and cataract surgery must be "personalized".

In simple terms, the doctor will develop the appropriate intraocular lens according to the patient's needs and optical aberration curve.

Factors to consider include:
The patient's age, lifestyle, expectations for vision, state after refractive surgery, corneal topography map, tomography, aberrations, eye surface health, pupil size, and macular health, etc.

 The new technology can accurately assess these factors, so that doctors can tailor cataract surgery to your eye condition for optimal vision after surgery.

In addition to the technical aspects of the assessment, the doctor also recommends that the details of cataract surgery be determined by visual needs: hobbies, choice of reading glasses, close-up workload, need to drive at night, etc.

Optimal vision after cataract surgery depends on accurate preoperative assessment and measurement, surgical technique, and careful selection of implanted intraocular lenses.

Procedures tailored to an individual's eye condition can also help better correct astigmatism and/or presbyopia. Astigmatism is when light is focused differently and blurs vision at long and close range; Presbyopia is the loss of near vision with age.

 Therefore, cataract patients are no longer limited to simply replacing their cloudy cataract with implanted intraocular lenses, but through personalized surgical formulation, to help patients obtain high-definition vision after cataract surgery.

Cataract _ lens dysfunction syndrome

Cataract rejuvenation Lens dysfunction syndrome

Rejuvenation of cataracts Lens dysfunction syndrome: With the development of science and technology, urban people cannot do without mobile phones and computers every day, and they watch screen for a long time, not only their eyes are tired, but also very hurtful. At the same time, cataracts tend to be younger.

There was a middle-aged patient who found that myopia continued to increase, and there was double shadowing of things. Upon closer examination, Dysfunctional Lens Syndrome (DLS) was found.

Dysfunctional Lens Syndrome (DLS) is a ubiquitous condition that has long been overlooked. The disease usually occurs at a young age, and although cataracts are not yet mature, the characteristics of the syndrome appear because the patient describes cataract symptoms.

In layman's terms, DLS can be considered a precataract, where the lens begins to harden, loses its ability to focus and near vision, and decreases in contrast and night vision. Ophthalmologists use advanced diagnostics to show cataract density, the refraction of light through the lens, or slit lamp photographs to help us understand the characteristics of this aura state associated with a patient's vision loss.

Early cataract patients have inconspicuous symptoms, common include: easy tiredness of both eyes, photophobia, glare problems, double shadowing of things, and frequent changes in diopters. The conventional wisdom is that cataracts must be "cooked" before surgery, but the truth is that the opposite is true, overripe cataracts will only worsen the condition and make patients miss the best time for treatment. If your vision is affected by your daily life or work, surgery can be performed. With the advent of advanced diagnostic methods, advanced technologies, the choice of multifunctional intraocular lenses and laser cataract surgery, lens dysfunction syndrome is easier to identify and treat.

Cataract

Who is most likely to have cataracts?

Who is most likely to have cataracts?

Cataract refers to the lens of the eye becoming cloudy and affecting vision, which used to occur mostly in people aged 60 or above, but in recent years, more and more relatively young people seek medical treatment for cataracts, generally between 40-50 years old, and generally suffer from deep myopia (i.e. 600 degrees myopia or above).

Long-term use of solids or cataracts

Cataracts have many risk factors: People who have diabetes or use steroids for a long time have a better chance of developing cataracts in the long run. An 18-year-old boy suffering from eczema sought medical attention because his vision became blurred, and it was finally confirmed that he had cataracts and had to undergo intraocular lens replacement surgery. After careful questioning of the medical records, the patient's whole body skin was plagued by eczema for many years, and he had sought help from different Chinese and Western medicines, and even divine doctors, and applied ointments of unknown composition for a longer period of time, hoping to control the disease, so it was suspected that the drug contained steroids, causing cataracts. Therefore, patients are advised to use steroid ointments under the supervision of a doctor, and if the origin or composition of the product is unknown, they should be carefully checked first.

In addition, having had iritis, having suffered a violent impact on the eye, having undergone eye surgery, or suffering from acute glaucoma are all causes of cataracts.

Deep myopia may have a greater impact on cataracts. It is generally estimated that too deep myopia can exacerbate the degenerative problem and form cataracts. Younger cataract patients, generally find that myopia suddenly deepened by 200, 300 degrees, to change glasses frequently, after trying once or twice, feel unusual, so find an ophthalmologist examination, only to find that they have cataracts. There are also patients who have symptoms such as double vision and photophobia when looking at images, and are found to have cataracts after eye examination.

Removal of cataracts without waiting for "cooking"

Cataracts are not only common, but also a major cause of vision loss. At present, there are no drugs to treat cataracts, and patients need to undergo surgery to replace the intraocular lens to restore their original vision. And many people think that cataracts need to be "familiar" before surgery, this statement is actually a misunderstanding, especially for some younger patients, if cataracts have greatly affected daily life and work, especially looking at documents, using computers, and even going out to drive, etc., it is already suitable for cataract removal surgery.

Through a small corneal incision, the doctor removes the cloudy lens and implants an intraocular lens. If you have a developing cataract, you don't have to wait until maturity to remove it, it usually only takes about 15-20 minutes. In most cases, doctors can use local anesthesia, which speeds up recovery time.

FLACS FEMTIC SECOND LASER-ASSISTED CATARACT SURGERY

FLACS FEMTOSECOND LASER CATARACT SURGERY

The application of FLACS femtosecond lasers in the field of refractive surgery has brought great changes. Laser vision correction such as LASIK and SMILE are widely used in refractive surgery. However, femtosecond laser-assisted cataract surgery (FLACS) provides doctors with a highly accurate alternative to the less predictable and technically demanding steps of traditional cataract surgery.

Current technology

Generally, cataract surgery is performed under local anesthesia, and the doctor uses a microscope in the operating room to remove the originally cloudy lens and implant a suitable intraocular lens using ultrasound emulsification technology.

icon_comparison

Technology

Connected to an optical imaging system, FLACS guides lasers to perform corneal incision, anterior capsulotomy, and lens fragmentation steps, bringing new options to patients and changing the requirements associated with traditional techniques.

BENEFITS OF FLACS FEMTOSECOND LASERS

FLACS femtosecond lasers are designed to provide safety and ease of operation while improving accuracy and refractive results. Many of the key steps of cataract surgery, such as anterior capsulotomy and lens removal steps, involve corneal incision structure, anterior capsule size, shape, and position of the intraocular lens to the optic axis.

  • Precise corneal incisions provide better wound healing
  • Predicts astigmatism and lower risk of endophthalmitis
  • Reduces ultrasonic emulsification time and energy
  • May reduce damage to corneal endothelial cells and other complications such as corneal and macular edema.
  • Precise anterior capsulotomy effectively predicts lens position
  • Greatly improve and exert the effect of high-end intraocular lenses on vision

Common cataract misunderstandings

Common cataract misunderstandings

Cataract is one of the major eye diseases that causes blindness in the elderly, but there are still many misconceptions surrounding its symptoms and treatments, the most common of which are the following:

number-one (1)

Can only the elderly get cataracts?

Cataracts can affect anyone, from babies to people in their 90s.

Long-term exposure to UV rays may worsen cataracts, but even people who avoid UV rays can still develop cataracts as they get older.

In addition to older factors, cataracts can be caused by congenital, traumatic, diabetes, drugs and radiation. 
number-2

Is cataract surgery no longer necessary at 80?

Cataract is a major eye disease that causes blindness in the elderly. Even if they are not blind, the elderly will be in a state of blurred vision for a long time, which will not only seriously affect the quality of life of the elderly, but also cause danger.

There are currently no effective drugs to treat cataracts, and the ideal way to treat cataracts is surgery, remove the cloudy lens, and replace it with an intraocular lens.

Regardless of age, cataract surgery can be considered if necessary and medically permitted.

number-3

Can cataract surgery only be performed on fully fledged cataracts?

Not. Patients do not need to wait for cataracts to mature.

In the advanced stage of cataracts, the lens will expand or even dissolve, which in turn will cause glaucoma, resulting in irreversible blindness, and advanced cataract surgery is more difficult and vision recovery is slower.

number-four

Can cataract surgery be painful?

Cataract surgery mostly involves ocular anesthesia, which is very painful and acceptable to most elderly people.

It has been reported in the literature that compared with cataract surgery in the first eye, the pain of patients undergoing cataract surgery in the second eye is slightly increased. 
number-5

Is the IOL short life?

At present, the material of intraocular lenses has very stable physical and chemical properties, and patients can use them for life. 

Must poor vision be caused by cataracts?
Will my vision improve immediately after cataract surgery?

Cover image_Selection of intraocular lens_Elements of selection of intraocular lenses

How do I choose an intraocular lens?

When you are facing cataract surgery or need to correct vision problems, choosing the right intraocular lens is a critical decision. What is an intraocular lens? It is an implantable lens used to replace cataracts or correct vision, consisting of an optical part and a fixed bracket, made of an elastic material such as plastic or silicone. There are many types including single focal length, astigmatism, presbyopia correction, multifocal length, and extended depth of field (EDOF). Each type has its characteristics, such as a single focal length that focuses on clear vision at a certain distance, while multifocal length and EDOF provide a different range of clear vision.

In this article, we'll explore each of their features and conditions to help you make the best choice based on your lifestyle and vision needs.

How to choose an intraocular lens for cataracts

Since everyone's condition and needs are different, and intraocular lenses are not as easy to replace as glasses, you should understand with your doctor before cataract surgery and choose the IOL that suits you.

One of the most important decisions that must be made before cataract surgery is which intraocular lens to choose. The patient's overall eye health (dry eye, corneal astigmatism, macular health, etc.), vision needs, and lifestyle play an important role in determining which intraocular lens will provide the best results for the patient.

It is suggested that the main decision that patients need to make is what kind of vision they want after surgery, such as:

number-one (1)

Good distance vision, but wearing reading glasses.

number-2

Good distance vision + – Monovision
Distance vision in one eye and reading vision in the other. However, it will affect part of the three-dimensional sense.

number-3

Relatively good distance vision + reading field of view, but it takes time to get used to.

lifestyle

When considering your lifestyle, if you need to drive frequently in your daily life, it is recommended to choose a lens that can provide good farsightedness to ensure safe driving. For photography enthusiasts, it is more appropriate to choose lenses that enhance near and intermediate vision, so that details can be clearly captured when shooting. For sports, especially those that require quick reflexes and accurate distance judgment, it is recommended to choose lenses with both good distance vision and intermediate and near vision to improve sports performance.

Job requirements

If your work involves using a computer for a long time, it is wise to choose a lens that provides good near and intermediate vision in order to reduce eye strain and reduce the risk of myopia. For professionals who need fine vision for detailed observation in their work, choosing a lens with excellent both distance and near and intermediate vision will ensure that you can clearly see the details as you work.

Types of intraocular lenses

Modern intraocular lenses are made of biocompatible materials such as acrylic or silicone and do not cause allergic reactions with the human body. In the past hundred years, there have been no cases of aging intraocular lenses affecting vision. So, don't worry about intraocular lens life.

Cataract surgery and intraocular lens implantation are quite advanced today, and the need for glasses after surgery depends on the type of lens implanted. Intraocular lenses are generally divided into three types: monofocal, multifocal and omnidirectional wide vision, and which one to use depends on the patient's lifestyle Xi habits and needs, each with its own advantages.

1

Unifocal intraocular lens

Monofocal intraocular lenses provide clear distance vision and better night vision, and the procedure is relatively simple and low-risk.

However, the disadvantage of this lens is that it does not improve near vision and astigmatism and spherical aberrations, resulting in the patient may need to wear reading glasses to correct myopia.

For patients who don't need clear vision at close or don't mind reading glasses, a monofocal intraocular lens is a suitable option

number-2 (1)

All-round wide view of intraocular lenses

Providing patients with a wide range of fields of view means that patients can see their surroundings more clearly, which greatly reduces their reliance on glasses in their daily lives.

However, this lens may have an impact on the contrast of vision, especially when looking at objects near and far, and the quality of vision may be reduced. In addition, it may take a long time for the patient to adjust to this new visual experience, especially when adjusting the focal distance.

number-3 (2)

Trifocal intraocular lens

It is suitable for people with presbyopia + cataract, and is a multi-functional intraocular lens with far, medium and near vision, and has a low dependence on glasses after surgery. It greatly improves the patient's satisfaction with the whole vision, and the performance of night vision is also better than other types of intraocular lenses.

However, it will take some time for the patient to get used to this new visual effect after implantation, as the trifocal lens provides clear vision in the specific three focal points, rather than a smooth transition like a natural eye.

Modern intraocular lenses are made of biocompatible materials such as acrylic or silicone and do not cause allergic reactions with the human body. In the past hundred years, there have been no cases of aging intraocular lenses affecting vision. So, don't worry about intraocular lens life.

Today, cataract surgery and intraocular lens implantation are quite advanced, and whether glasses are required after surgery depends on the type of lens implanted. Intraocular lenses are generally divided into three types: monofocal, multifocal and all-round wide vision, which one is mainly used depends on the patient's living habits and needs, each with its own advantages.

Due to the limitations of optical design, monofocal lenses require glasses to correct near vision after surgery. The new generation of advanced monofocal high-definition intraocular lenses not only improves the field of view and improves mid-range vision - it provides a longer depth of field than traditional monofocal intraoplastic lenses, and is more convenient in life such as reading bus numbers and computers, while retaining the benefits of clear images and no glare problems.

In addition, the recently launched new generation of continuous intraocular lenses, which provide a wide continuous field of view from a distance to a reading distance of 33 cm, eliminates the visual gap present in trifocal technology and other multifocal technologies, allowing patients to experience continuous high-contrast vision from far to near even in low-light conditions, greatly reducing the dependence of cataract patients on glasses. Its UV light filtering technology also helps to reduce glare and halo intensity when driving at night.

Traditionally, ophthalmologists rely on patients to communicate about visual behavior in oral or questionnaire form, and the information provided can be misleading due to memory biases. Now, patients can record information on daily activities such as: lifestyle and time ratio on TV, tablet, smartphone - outdoor activities, driving, etc. by wearing a glasses monitor, providing data and objective measurements of patient behavior.

As the system processes and analyzes, the records are uploaded and converted into patient behavior data using AI operations. The report records are divided into three visual distances, with a percentage set for the near, medium and far ranges, which facilitates more efficient selection of the most suitable IOL solution.

How long does an intraocular lens last?

Intraocular lenses are made of biocompatible materials such as acrylic or silicones. This means that they do not react with the human body anaphylaxis. For more than 100 years, no cases of aging intraocular lenses affecting vision have been found. So, don't worry about intraocular lens life. IOLs live longer than anyone can live, and rare IOLs change and need to be replaced.

How long can an intraocular lens last? Are there any side effects of intraocular lenses?

The most important factor in vision recovery in cataract surgery is whether the eye itself has other diseases, such as macular degeneration; Or diabetics, retinopathy caused by long-term high blood sugar.

 

Corneal opacity, glaucoma and other factors can limit vision recovery after surgery.

This group of patients remembered not to use "multifocal intraocular lenses", because the visual quality caused by the reduction of contrast was reduced, and it was not clear to see near and far.

Intraocular lens sequelae?

Although intraocular lens surgery is safe and effective in most cases, there are still some possible sequelae and complications. Here are some of the intraocular lens sequelae that can occur:

  1. Infection or aseptic inflammation in the eye: After surgery, the eye may become infected or inflamed. This may require additional treatment and medication to control.
  2. Corneal edema: After surgery, the cornea may experience edema, which can cause blurred vision or discomfort.
  3. High intraocular pressure: After surgery, intraocular pressure may increase, which may require additional treatment to control.
  4. Poor wound healing: Surgical wounds may not heal properly, which may require further treatment and observation.
  5. Retinal edema or detachment: After surgery, the retina may experience edema or detachment, which can lead to vision problems.
  6. Intraocular lens displacement: Intraocular lenses may be displaced after surgery, which may require further surgery to correct.
  7. Residual lens fragments in the eye: During the procedure, some lens fragments may remain in the eye, which may require further treatment and observation.

In addition to these possible sequelae, there are some other complications that may occur but are less likely, such as retroocular hemorrhage, intraocular hemorrhage, intraocular hemorrhage, intraocular hemorrhage, and crystal nucleus displacement.

What is the price of intraocular lenses?

The fee depends on the length and complexity of cataract surgery, including tools, instruments, drugs and consumables required for the operation. For details, please contact WhatsApp/by phone.
