Abstract
An Accommodating Intraocular Lens (AIOL) is disclosed herein, that is comprised of a flexible optic and a flexible haptic rim that conforms to the human eye capsule. The spherical or custom shape of the optic is engineered to be maintained during accommodation through the mechanical/optic design of the implant and the interaction between the implant and the naturally occurring position and actuating forces applied through ciliary muscle/zonules/and capsule as the brain senses the need to increase the diopter change or magnification when an object of fixation approaches the eye. The axial relocation or position of the AIOL may also be further adjusted anatomically to further improve the affect needed to achieve improved accommodation. Optionally, the accommodating intraocular lens is foldable or injectable for delivery of the lens into the eye.
