发明名称 Intraocular lens for double-fold implantation
摘要 A elastically deformable intraocular lens (IOL), adapted for double folding and implanting in the iridocorneal angle or ciliary sulcus of an eye. The IOL includes an optic having a long axis and an orthogonal transverse axis passing through the optical axis and a diameter of between about 5 mm and about 7 mm. First and second fixation members are joined to or at opposite edge regions of the optic. The first fixation member is generally pi-shaped, having a base region with a width parallel to the transverse axis no greater than about 3 mm, and includes a pair of similar, spaced apart haptics, proximal ends of which are symmetrically joined to the base region and which diverge outwardly from the long axis at between about 30 and about 45 degrees. The two haptics are constructed to flex in the plane defined by the unflexed haptics during IOL double folding of the IOL and unflex in the same plane after the IOL is implanted in an eye. The second fixation member may be similar to the first fixation member for IOL "four-point" ocular tissue contact or may have only a single haptic for IOL "three-point" ocular tissue contact.
