Abstract

Methods of adjusting an intraocular lens after implantation. In some embodiments the methods include positioning an accommodating intraocular lens within an eye, the intraocular lens comprising an optic portion in fluid communication with a peripheral chamber, wherein movement of a fluid between the peripheral chamber and the optic portion in response to ciliary muscle movement changes the optical power of the lens, and reducing a power of the intraocular lens by causing the fluid to move between the optic portion and the peripheral chamber, wherein the reduction in power of the intraocular lens is not in response to ciliary muscle movement, and wherein the positioning step occurs prior to reducing the power.

First claim

What is claimed is:

1. A method of adjusting an accommodating intraocular lens after implantation, comprising:
implanting an accommodating intraocular lens comprising an accommodating fluid in a lens capsule of an eye, wherein the accommodating intraocular lens changes power in response to ciliary muscle movement that causes movement of the accommodating fluid between an optic chamber and a peripheral chamber;
altering fluid pressure within at least a portion of the accommodating intraocular lens to accommodate for a healing response of the lens capsule after implanting the accommodating intraocular lens, wherein the implanting step occurs prior to the altering step; and wherein altering fluid pressure within at least a portion of the accommodating intraocular lens comprises severing one or more components of the accommodating intraocular lens.

2. The method of claim 1 , wherein altering fluid pressure within at least a portion of the intraocular lens comprises decreasing fluid pressure within the optic portion.

3. The method of claim 1 , wherein altering the fluid pressure comprises moving a portion of the fluid from the optic portion to the peripheral portion.

4. The method of claim 1 , wherein the severing step comprises applying laser energy to the one or more components.

5. The method of claim 1 , wherein the severing step changes the power of the intraocular lens.
