Abstract
A method for prevention of migration of epithelial cells in a capsular bag of an eye of a mammal is provided. The method comprises removing the natural lens of the eye from the capsular bag; introducing an object with at least one sharp edge into the capsular bag, in such a way that said sharp edge contacts the inside of the capsular bag to form a barrier preventing migration of epithelial cells across said barrier; and injecting a lens-forming composition into the capsular bag.

Method for forming a lens in situ in an eye of a mammal, comprising:
- removing the natural lens of the eye from the capsular bag;
- introducing an optic with a radius and at least one sharp edge into the capsular bag and positioning the optic within the capsular bag with the at least one sharp edge contacting an inside wall of the capsular bag;
- wherein the radius of the optic is large enough such that the optic will span a diameter of the capsular bag at approximately the equator so as to push the at least one sharp edge against the inside wall of the capsular bag at approximately the equator to create a barrier;
- injecting a lens-forming composition into the capsular bag to fill the capsular bag;
- and
- curing the lens-forming composition to form a lens having an outer circumference, wherein the formed lens completely fills the capsular bag and the at least one sharp edge remains in contact with an inside wall of the capsular bag after lens formation;
- wherein the optic has optical properties that may be used in combination with optical properties of the injected lens-forming composition.

Method for forming a lens in situ in an eye of a mammal, comprising:
- removing the natural lens of the eye from the capsular bag;
- introducing an optic with a radius and at least one sharp edge along an outer circumference of the optic into the capsular bag and positioning the optic within the capsular bag, with the at least one sharp edge contacting an inside wall of the capsular bag;
- wherein the radius of the optic is large enough such that the at least one sharp edge will push the inside wall of the capsular bag at approximately the equator to create a barrier;
- injecting a lens-forming composition into the capsular bag to fill the capsular bag;
- and
- curing the lens-forming composition to form a lens having an outer circumference, wherein the formed lens completely fills the capsular bag and the optic remains in the capsular bag, the at least one sharp edge remaining in contact with an inside wall of the capsular bag after lens formation by curing of the lens-forming composition;
- wherein the optic has optical properties that may be used in combination with optical properties of the injected lens-forming composition.
