  • Extracapsular cataract surgery is the removal of the lens where the capsule is left in place.

    There are two methods for extracapsular cataract surgery. The usual technique is phacoemulsification. A tiny incision (about 0.12in or 3 mm long) is made next to the cornea (the eye’s outer covering), and an ultrasonic probe is used to break the cataract into minute pieces, which are then removed by suction.

    When the lens is too hard to be emulsified ultrasonically, the surgeon will use a different extracapsular technique requiring a larger incision. An incision about 0.37 in (9 mm) inches long is made, and the whole lens (without its capsule) is removed through the incision. Both kinds of extracapsular extraction leave the back of the capsule intact, so a silicone or plastic intraocular lens can be stably implanted in about the same location as the original lens.

    The surgery takes about 30-60 minutes per eye.
