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.
Claims18
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 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;
- 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 a lens having an outer circumference, 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;
- wherein the object is disposed along the outer circumference of the lens.
Method according to claim 4, wherein the object with at least one sharp edge contacts the inside wall of the capsular bag along at least 90% of the equator of 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 object with at least one sharp edge having a radius of less than 2 μm 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;
- 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 object remains in the capsular bag, the 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 object is disposed along the outer circumference of the lens.
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 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;
- 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 sharp edge remains in contact with an inside wall of the capsular bag after lens formation;
- wherein the sharp edge extends radially outward from the lens.
