Buffer-containing devices for preventing clouding of posterior capsule after extracapsular cataract eye surgery and method of performing cataract surgery

摘要

The present invention relates to devices for killing undifferentiated epithelial cells during cataract surgery on an eye to prevent posterior capsule clouding after the surgery and to a method for performing cataract surgery on an eye including injecting a cell-killing substance between the anterior capsule and the natural lens prior to removing the natural lens from the eye. The cell-killing substance is preferably an acid or base adjusted, aqueous, buffer-containing a solution having a pH in the range between about 1.0 to below 6.5 or about above 7.5 to 14.0 or a buffer-containing hypotonic solution having a salinity less than 0.06%. The devices of the present invention optionally incorporate a viscoelastic material, a dye or a mixture thereof, in combination with the cell-killing substance.
