Abstract
A method for treatment of residual lens epithelial cells is disclosed. The method provides increased safety during local treatment in ocular surgery by improved administration of active agents. The method is particularly useful in treatment of proliferative events in ocular surgery, such as posterior capsular opacification.
Claims29
A method of preventing posterior capsule opacification (PCO) from occurring after cataract surgery, comprising the steps of:
- filling the anterior chamber (5) of an eye with a viscoelastic solution (13), to maintain the depth of the anterior chamber (5) and to prevent gas (14) from leaking out from the lens capsule (8),
- expanding the lens capsule (8) and keep it expanded, and injecting an active agent (14;15), toxic to lens epithelial cells, into the lens capsule (8).
A method of administration of substances active against lens epithelial cells, comprising the steps of:
- filling the anterior chamber (5) of an eye with a viscoelastic solution (13), to maintain the depth of the anterior chamber (5) and to prevent gas (14) from leaking out from the lens capsule (8),
- expanding the lens capsule (8) and keep it expanded, and injecting an active agent (14;15), toxic to lens epithelial cells, into the lens capsule (8).
