<p>A method to provide an efficient, safe, and easy to use supracapsular method for removal of cataracts, wherein a groove (52) is formed in the cataract nucleus (56, 58) is cracked along the groove (52) into two halves and rotated approximately 90 degrees, force is applied to the proximal half to effect movement of the distal half into a stacked position relative to the proximal half, and the nucleus halves (56, 58) along with the remainder of the cataract are then emulsified and removed. In order to minimize the chances of trauma to the capsule while sweeping the lens capsule away from cataract portions as well as making a crack in the nucleus and for otherwise assisting in manipulation of nucleus portions, an instrument has a prongless cataract-engaging portion, preferably with a convex frontal edge.</p> |
