Symptoms of dry eye
It sounds contradictory that watery eyes are a symptom of dry eye, but it is.
This is because your body usually produces too many tears to help relieve these symptoms.
Causes [reflex surname tear secretion]. However, this is usually only used as a temporary remedy.
Our tears are made up of water (water-based), oil (lipids), and mucus (mucin). There are two main forms of dry eye: dehydration and evaporation.
When a person suffers from the watery form of dry eye, the tear glands in the eye do not produce enough tear-like components.
IN EVAPORATION, IT IS CAUSED BY MEIBOMIAN GLAND DYSFUNCTION (MGD), IN WHICH THE OIL LAYER OF THE TEAR FILM IS INSUFFICIENT.
MGD AFFECTS MOST PEOPLE WITH DRY EYE.
MEIBOMIAN GLAND DYSFUNCTION (MGD) IS A BLOCKAGE OF THE MEIBOMIAN GLANDS SO THEY DON'T SECRETE ENOUGH OIL IN THE TEARS.
BECAUSE THE TEAR FILM ON THE OCULAR SURFACE EVAPORATES TOO QUICKLY, MGD IS ASSOCIATED WITH DRY EYE.
It is also associated with eyelid problems in blepharitis.
Some studies have found that as much as 69% of the Asian population suffers from meibomian gland dysfunction, which cannot be ignored.
Association of allergies with dry eyes
Hong Kong weather is humid and hot, easy to appear different sensitivity, if children often eye marks, runny eyes, eye picking, etc., it may be eye sensitivity, it is recommended that parents observe the child's condition more to help the child avoid allergens, so as to avoid the child randomly twisting the eyes and causing corneal inflammation, affecting vision.
If symptoms persist, parents should take their children to the doctor, and the doctor will prescribe eye drops containing "antihistamine" or preservative-free moisturizing drops to relieve itching, while drops containing "mast cell stabilizers" can prevent eye sensitivity and recurrence.

If the eye dry eye drops should be chosen.
In most cases, eye drops are mainly divided into three types:
- Artificial tears
- Anti-allergic eye drops: "Antihistamine" eye drops or drops containing "mast cell stabilizer" can prevent eye sensitivity and hair recurrence.
- Vasoconstrictor eye drops: vasoconstrictors, not recommended for long-term use.
After dropping eye drops, it is best to use preservative-free eye drops
Some people are allergic to preservatives, while others may find that they irritate their eyes. When you're looking for preservative-free eye drops, be aware that they're not in a typical eye drop bottle. As a rule, you can find them in disposable vials. You remove the cap, drip in, and throw out the vial. They also tend to be more expensive than other species. If your dry eyes are more severe, you may need to use a long-lasting lubricating gel or ointment. Because gels and ointments can cause blurred vision, most people use them before going to bed.
Eye drops for a bitter throat, correct use of eye drops method
- Clean your hands
- From sitting, standing, or lying down with your head tilted back, place your index finger on the lower eyelid and gently pull down to form a pocket.
- Squeeze a drop of water into the lower eyelid .
- Close your eyes.
If your eyes are dry and irritated, you may go to the pharmacy on your own to buy eye drops. Eye redness is not necessarily dry eyes or eye sensitivity, there may be keratitis, pink eye and other conditions, such as using the wrong drug, not only can not be improved, but also may worsen the situation, so parents should let their children seek medical attention as soon as possible and receive appropriate treatment, and should not buy eye drops for their children to use indiscriminately. Incorrect use may cause your symptoms to worsen.

7 effective ways to eliminate eye fatigue.
If you feel {dry eyes headache, eye fatigue want to sleep}, you may suffer from this eye problem?
With the spread of computers, smartphones, tablets, etc., young eye patients are gradually increasing.
Most of the reasons for their medical treatment are tired eyes, dry eyes, etc., and sometimes accompanied by headaches, shoulder and neck pain and other symptoms. It turned out that this may be suffering from "computer vision syndrome".
The most common symptoms are:
- Eye fatigue and want to sleep
- Headache
- Blurred field of view
- Dry eyes
- Neck and shoulder pain
Computer vision syndrome
As for the specific cause of "computer vision syndrome", it is mainly due to "eye fatigue". The text or pattern on the computer screen is composed of elements or dots, and the formation of the ciliary muscle requires constant relaxation and contraction, which makes these muscles particularly loaded. In addition to this, these symptoms may form due to:
- Poor lighting
- Glare on a digital screen
- Incorrect line-of-sight distance
- Poor sitting posture
- Uncorrected vision problems
How to get rid of eye strain
Some important factors in preventing or alleviating symptoms
- Correct posture: Keep your body perpendicular to your feet, with the computer screen optimally positioned slightly below your eyes. The distance between the screen and the eyes, a 14-inch screen should be kept at least about 60cm, and a 15-inch screen should preferably have 70cm.
- Artificial tears are used to treat dry eyes.
- Use blinds or curtains on windows and use low-wattage bulbs.
- Massage or warm compress to the eyes while resting.
- Instead of staring at your computer screen for a long time, consider using a screen glare filter to reduce glare from light sources
- To reduce digital eye strain, follow the 20-20-20 rule; Take a 20-minute break for 20 seconds to look 20 feet away, relax your eyeballs, and slowly open and close your eyes 20 times to moisten your eyes.
- TO SUPPLEMENT EYE NUTRITION, YOU CAN EAT MORE FOODS CONTAINING VITAMIN A, SUCH AS CARROTS, SPINACH, TOMATOES, ETC.

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:
Good distance vision, but wearing reading glasses.
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.
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.
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
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.
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:
- 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.
- Corneal edema: After surgery, the cornea may experience edema, which can cause blurred vision or discomfort.
- High intraocular pressure: After surgery, intraocular pressure may increase, which may require additional treatment to control.
- Poor wound healing: Surgical wounds may not heal properly, which may require further treatment and observation.
- Retinal edema or detachment: After surgery, the retina may experience edema or detachment, which can lead to vision problems.
- Intraocular lens displacement: Intraocular lenses may be displaced after surgery, which may require further surgery to correct.
- 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.

Vision becomes blurred after cataract surgery, and 4 possible complications are being sedated.
Flash light after cataract surgery can be a sign of retinal detachment
The retina is located behind your eyes and senses light and sends information to the brain.
After surgery, you have a higher chance of pulling it away from the back of your eye – a problem known as retinal detachment.
This is an emergency and may cause vision loss.
See an ophthalmologist immediately if you:
- It feels like a curtain has fallen on your eyes
- There are new floating points in the line of sight
- Flash is often seen
Cataract recurrence? How to treat posterior capsular opacity
Recurrent cataract refers to the "posterior capsule" that is deliberately retained during cataract surgery to place the intraocular lens, and then thickens and becomes cloudy over a period of time. Although the condition is common, you may be more susceptible to recurrent cataracts for some reasons.
The younger the age of cataract surgery, the greater the likelihood of this thickening.
Fortunately, posterior capsular opacity does not need to enter the operating room for surgery, as long as the opacity of the posterior capsule is opened with a laser in the outpatient clinic, vision can be restored.
Cataract macular edema
Sometimes after surgery, blood vessels in the retina leak. When fluid accumulates in your eyes, it can blur your vision.
The first option is to be treated with eye drops, which can take weeks or months to recover.
In more severe cases, patients may need steroid injections behind the eye or surgery.
Eye infections.
Bacteria that enter your eye during surgery can cause infection.
You may be sensitive to light, or have pain, redness, and vision problems Infections after cataract surgery are rare and can usually be treated with antibiotics.
In some severe cases, doctors may remove a glassy clear gel from the center of the eye to stop the infection from spreading.
