Abstract
Cataracts are treated for removal by introducing a lenticular tissue dispersing agent into the opacified lens through a small opening in the lens capsule so that the capsule remains substantially intact. The tissue dispersing agent is contained in the lens by a gel-forming substance which functions to block the opening in the lens capsule, preventing its escape. This treatment is preferably carried out in conjunction with laser induced phacofracture.
