ABSTRACT:
An intraocular lens suitable for scleral fixation is provided, having a disk-shaped lens optic with two flexible haptics projecting outwardly from opposite points on the lens optic's periphery, each haptic including one or more suture holes for use in suturing the haptic to the ciliary sulcus of an eye during implantation surgery. The suture holes are positioned such that they are located substantially at the haptic apexes when the lens is implanted and the haptics have been flexed inwardly a predetermined amount. In addition, the suture holes are sized to be large enough to receive standard sutures, but small enough to prevent excessive movement of the haptic relative to the suture and to inhibit tissue ingrowth and incarceration. This configuration minimizes the possibility of lens tilting, decentration and rotation.
