Claim:
Method for forming an intraocular lens in situ in an eye of a mammal, comprising: removing the natural lens of the eye from the capsular bag; introducing an object with at least one sharp edge into the capsular bag and positioning the object within the capsular bag with the sharp edge contacting an inside wall of the capsular bag to form a barrier preventing migration of epithelial cells across the barrier; configuring the object to push against the inside wall of the capsular bag; injecting a lens-forming composition into the capsular bag to fill the capsular bag; and curing the lens-forming composition to form an intraocular lens in the capsular bag, wherein the formed lens completely fills the capsular bag and the sharp edge remains in contact with an inside wall of the capsular bag after lens formation to prevent migration of epithelial cells across the barrier in the capsular bag; wherein the object is a haptic of an intraocular lens, which haptic is provided with the at least one sharp edge.
