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.
