A thin foldable intraocular implant specifically configured for installation into the anterior chamber of a phakic or pseudophakic eye has broad positioning flaps that do not apply any substantial pressure against the wall of the eye. It can be rolled for insertion through a corneal incision as small as 2.75 millimeters. The implant is constituted by a two-layered resiliently flexible membrane having a corrective layer of about 50 to 130 microns and an overall thickness of about 150 to 530 microns, that vaults the iris without contacting it. The optic is constituted by a multi-order diffractive (MOD) structure, and is made of silicone, PMMA, hydrogel or hydrophobic acrylate. |
