Cataract Surgery/Clear Lensectomy
Cataracts develop generally as part of the ageing process – a ‘cloud’ forms in the lens of the eye, causing blurry or double vision and increased sensitivity to light. Cataract surgery is one of the most commonly performed procedures around the world today where a surgeon makes an incision, removes the defective lens and then replaces it with a new intraocular lens (IOL) to restore vision.
The surgical technique for the removal of the defective lens is called Phacoemulsification Surgery or Small Incision Cataract Surgery. Phacoemulsification is pronounced fay-ko-emul-sah-fah-kay-shun.
This procedure enables the removal of the cataract and implantation of the artificial lens through the mico incision (less than 3mm) and ensures little discomfort, a low chance of post-operative complications, fast healing time, and a quick return to normal activities.
Step 1 – Phacoemulsification
Once a small incision is made, a small tip is inserted to break the cataract into small fragments via ultrasonic vibration. These are then removed by suction via the incision.
Step 2 – Inserting the IOL
The artificial lens of choice is usually a foldable intraocular lens and can be folded to less than half its size, allowing insertion through the tiny incision. Once inserted, the lens unfolds to its normal full size. The incision is nomally so small that it often requires no stitches, or perhaps only one or two.
Step 3 – After Care
After surgery, the eye is covered with a shield for protection.
