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.
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
In summary, FLACS femtosecond lasers offer comparative advantages over traditional phacoemulsification cataract surgery techniques, especially when implanting high-order intraocular lenses in terms of accuracy, predictability and use in difficult situations such as mature cataracts.
