Cataract surgery involves the removal of the opaque lens surgically and replaces it with a clear artificial lens made of special material. Normally, cataract surgery is performed as day care surgery with local anaesthesia and some sedation.

Patient with pre-existing short sighted or farsighted refractive error may find that they do not need to wear thick glasses for best vision after cataract surgery. This is because the eye surgeon will normally choose an intraocular lens that will reduce the pre-existing refractive error. Thus, modern cataract surgery, especially phacoemulsification, can also be classified as a type of refractive surgery.

Cataract Removal :
An ultrasonic probe is inserted through a tiny incision. The probe break the cloudy lens into pieces, then vacuums them away. This is called phacoemulsification.

Lens Implantation :
The cataractous lens is replaced with an artificial intraocular lens(IOL). The IOL is inserted in precisely the right spot, where the haptics, or “arms”, gently unfold to keep it centered.

Vision Restored :
Once the Cataractous lens has been removed and replaced by the IOL, light once again passes through, focusing on the retina to provide a clear, sharp vision.

Phacoemulsification is the most advanced technique in cataract surgery. This technique involves using an ultrasound instrument to emulsify the lens and then aspirate the lens through a small incision.

There are a number of advantages from using a small incision:

	Earlier visual rehabilitation
	Minimal surgical induced astigmatism
	More predictable surgical outcome

However, due to the complexity of the surgery, the success of this surgery is highly dependent on the skills of the surgeon as well as good equipment. This is the surgery of choice recommended by our experienced eye surgeons. To complement the expertise of the eye surgeon, Centre for Sight uses modern equipment to provide a high quality eye surgery to our patients.

Day care surgery

Presently, most cataract surgery is being performed as a day care surgery. This means that the patient does not need to be hospitalised after surgery.
