A short haptic diameter modified J-loop intraocular lens for improved capsular bag performance.
The laboratory and clinical characteristics of a modified J-loop intraocular lens (IOL) are presented. The lens features a 6 mm polymethylmethacrylate optic with uniplanar polypropylene loops of a 12 mm overall haptic diameter. The haptic design has a low resistance to compression at all diameters down to 9 mm. The relationship of the haptic configuration to the architecture of the capsular bag facilitates easy capsular bag implantation and consistent IOL centration in eyes with small and moderate capsular bag diameters. Three hundred fourteen lenses have been implanted over a one year period with no instance of asymmetric capsular bag-ciliary sulcus IOL placement, optic decentration, or pupillary capture.
