Abstract

An improved single-piece flexible intraocular lens (420) with a radiused transition region (422) between a lens element (424) and a winged support portion (426) of the intraocular lens (420). The radiused transition region (422) is formed by a fillet portion (428). The fillet portion (428) is used to reinforce the re-entry angle formed by the intersection of the lens element (424) and the winged haptic portion (426). The fillet portion (428) is incorporated into the lens junction to reduce the stress on the intraocular lens (420) which occurred at the sharp transition corner of prior art lenses. A preferred radius for the transition region (422) is between 0.01 mm and 0.25 mm. The single-piece lens (420) with the transition region (422) having a fillet (428) between the optical element (424) and the winged haptic (426) is preferably formed by a single-piece mold (440) to provide the most control over the radius of the transition portion (422).
