What is advanced cataract surgery?
The eye’s lens refracts light that enters the eye to visualise pictures of scenes, people and things clearly. A healthy lens is typically clear, but it turns cloudy and impairs vision when a cataract forms. Cataracts are progressive, do not disappear naturally, and require surgery to be removed. When people cannot see as clearly and keep up with their demanding lifestyles because of their vision, they must undergo cataract surgery. Cataract surgery removes a damaged, murky lens that is replaced with a new, artificial intraocular lens (IOL). Modern and advanced cataract surgery is a painless procedure that can be performed as an outpatient procedure in under 10 minutes.
How do we perform cataract surgery?
Phacoemulsification cataract surgery is a type of procedure where ultrasound is used to remove the cataract before implanting a new artificial lens. Firstly, the surgeon creates a microincision in the cornea. Next, he/she creates a 5.5mm circular opening in the capsule containing the cataract. Then the surgeon utilises a miniaturised probe, which uses high-frequency sound waves to emulsify or break apart the cataract while a suction sleeve simultaneously removes the cataract fragments. Finally, they replace the old lens with a 6mm diameter artificial intraocular lens which is rolled into an implantation device so that it can be delivered through a 2mm opening.
Laser guidance cataract surgery is a form of cataract surgery performed using a laser guidance system to ensure the surgeon makes his/her incisions and implants the artificial lens in the exact locations required to correct astigmatism and optimise surgical outcomes.
