Curvature-changing, accommodative intraocular lenses with expandable peripheral reservoirs

A method of treating a vision disorder, comprising:

• inserting an intraocular lens within the capsular bag of a patient's eye, the intraocular lens comprising:
• a deformable outer shell having a distal end and a proximal end;
• a fluid optic having at least one elastic membrane surface at least partially defining an internal chamber to hold an optical fluid;
• an inner shell associated with the fluid optic having a distal end and a proximal end, each end joined to a corresponding distal end and proximal 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 of the optic
• disposing the fluid optic within the capsular bag such that the elastic membrane is disposed across an optical axis of the eye;
• and
• disposing the intraocular lens within the capsular bag such that axial compression of the capsular bag causes deformation of the deformable outer shell 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.
