There are several surgical techniques for cataract removal. The operating surgeon is the best person to decide which technique is likely to yield the best result. Intracapsular cataract surgery: The entire cataract is removed from the lens of the eye. This technique is now redundant and obsolete. Extracapsular cataract surgery: The posterior capsule of the lens is not removed and is left behind to act as a support for intraocular lens implantation. Both these procedures require a large incision and stitches which are removed after a short interval Phacoemulsification: This technique removes the cataract through a small 2 mm incision in the eye.
