Intraocular implant devices

An intraocular adaptive optic device for placement in an enucleated capsular sac, comprising:

• a device body comprising a plurality of peripheral body portions that carry curvilinear shape memory alloy (SMA) forms therein that define a first memory shape for engaging and imparting an accommodative physiologic shape to the equatorial and peripheral regions of the capsular sac, said peripheral body portions capable of flexure to a second tensioned shape that corresponds to a disaccommodative shape of the capsular sac, said peripheral body portions transitioning from an annular body portion;
• a central adaptive optic element coupled to the annular body portion, the optic element defining anterior and posterior surfaces wherein at least one surface is deformable in response to a change in fluid volume in an interior space therein to adapt the optic between first and second powers;
• and
• at least one peripheral chamber in said peripheral body portions and flow means between said interior space and said peripheral chamber(s), wherein flexure of said peripheral body portions between said first and second shapes alters the volume of said peripheral chamber(s) to move a fluid media to or from said interior space to adapt the optic element between said first and second powers.

An intraocular lens, comprising:

• a polymer implant body dimensioned for intracapsular implantation that defines a central optic portion and a peripheral non-optic portion for engaging the capsular sac;
• the optic portion defining anterior and posterior surfaces wherein at least one surface is deformable in response to media displacement within an interior space therein to alter lens power;
• and
• the non-optic portion of a shape memory polymer that defines a substantial cross-section in a memory shape for preventing collapse and contact of the anterior and posterior lens capsules, said non-optic portion carrying at least one interior chamber in fluid communication with said interior space, wherein said interior chamber(s) are deformable in response to zonular tensioning and de-tensioning to cause media displacement between said interior chamber(s) and the interior space.
