Techniques for Cataract Surgery

It is not always likely that surgery of two different people who are diagnosed with cataract are same. The techniques varry with the patient and the size of the cataract. There are three basic techniques for cataract surgery:

Phacoemulsification: This is the most common form of cataract removal. In this most modern method, cataract surgery can usually be performed in less than 30 minutes and usually requires only minimal sedation. Numbing eyedrops or an injection around the eye is used and, in general, no stitches are used to close the wound, and often no eye patch is required after surgery.

Extracapsular Cataract Surgery: This procedure is used mainly for very advanced cataracts in which the lens is too dense to dissolve into fragments. This technique requires a larger incision so that the cataract can be removed in one piece without being fragmented inside the eye. An artificial lens is placed in the same capsular bag.

Intracapsular Cataract Surgery: This surgical technique requires an even larger wound than extracapsular surgery, and the surgeon removes the entire lens and the surrounding capsule together. This technique requires the intraocular lens to be placed in a different location, in front of the iris. This method is rarely used today but can still be useful in certain situations.
