In order to remove the cataract and replace it with a new lens, your surgeon will make an incision in your eye. Where the incision is made and how large it will be depends on the technique (ECCE or phaco) he chooses for you.

Incisions can be made in either of two places in your eye - clear cornea or the sclera. The cornea is the transparent area of your eye over the iris and pupil. The sclera is often referred to as the white part of your eye.

The ECCE removal technique requires a large incision in the sclera. The phaco technique requires a smaller incision in either the sclera or clear cornea. Smaller incisions usually result in little discomfort during or after surgery, often do not require stitches, can aid in reducing astigmatism, and may provide a faster postoperative recovery period.
