Abstract

An intraocular lens includes a deformable outer shell having a distal end and a proximal end, a fluid optic having at least one elastic membrane surface positioned to traverse an optical axis of a patient's eye and at least partially defining an internal chamber to hold an optical fluid, and an inner shell associated with the fluid optic having a distal end and a proximal end. Each end is joined to a corresponding end of the outer shell to define a reservoir between the inner and outer shells, the reservoir at least partially disposed about a circumference of the fluid optic and in fluid communication with the internal chamber. The deformable outer shell is configured to deform upon axial compression of the capsular bag in a manner that increases the volume of the reservoir and draws fluid from the chamber into the reservoir, modifying a curvature of the elastic membrane.
