Method and apparatus for accommodating intraocular lens
First Claim
1. A method of replacing a natural lens in an eye, comprising the steps of:
- removing at least a portion of the natural lens while leaving the capsular bag substantially intact;
injecting a synthetic material into the capsular bag to form an artificial lens including loose monomers;
placing biodendrimer within the capsular bag; and
selectively exposing portions of the artificial lens to an energy source to alter the refractive properties of the artificial lens to change its volume to a predetermined volume to correct a predetermined refractive error when exposed to an energy source.

Abstract
A method of replacing a natural lens in an eye is presented. The method includes removing the natural lens while leaving the capsular bag substantially intact, removing a portion of the capsular bag along the main optical axis, and placing biodendrimer within the capsular bag. Placing biodendrimer within the capsular bag can include placing a mixture of biodendrimer and at least one other material within the capsular bag. Biodendrimer can be approximately fifty percent of the mixture. The method can also include inserting an artificial bag within the capsular bag, injecting a synthetic material into the artificial bag to form an artificial lens, the synthetic material having loose monomers and a polymerization initiator so that the synthetic material changes its volume when exposed to an energy source, and selectively exposing portions of the artificial lens to an energy source to alter the refractive properties of the artificial lens.

21. A method of modifying the optical properties of an eye, comprising the steps of:
coating at least a portion of an external surface of a capsular bag with a synthetic substance, wherein the synthetic substance includes biodendrimer and an unpolymerized material positioned having loose monomers and a polymerization initiator so that the unpolymerized material changes the shape of the flexible capsule when exposed to an energy source.

22. An intraocular lens, comprising:
-
a flexible capsule adapted to be inserted into the natural lens capsular bag; a polymerized portion, including biodendrimer, positioned within said flexible capsule; and an unpolymerized material positioned within said flexible capsule, and having loose monomers and a polymerization initiator so that the unpolymerized material changes the shape of the flexible capsule when exposed to an energy source; wherein said unpolymerized material is capable of changing the shape of the flexible capsule, such that the flexible capsule is multifocal.
