  • Abstract
  • Look Inside

We developed a prototype of flexible disc intraocular lens with closed circular haptics. The lens is of single-piece construction. It has a 5mm PMMA optic and a 10.5~11.5mm outer ring connected to the optic with three inner arms. The thin, 0.12mm×0.16mm elliptic cross section of the outer ring and the inner arms give good flexibility to the disc lens. It enables an easy insertion through a 6.5~7.0mm corneoscleral incision and fixation in the bag through a 6 mm capsulorhexis opening. The state of lens fixation in pig cadaver eyes was stable and well-centered. The lens implanted in live rabbit eyes showed no tilting or decentration and did not cause rupture of the capsular bag or the lens zonules.
