Spontaneous disinsertion of an iris-fixated 3-piece intraocular lens haptic from the optic in a patient with pathologic myopia

Abstract

A 39-year-old man with pathologic myopia and a dislocated native lens of the right eye underwent pars plana lensectomy and implantation of an iris-fixated 3-piece MA60MA foldable acrylic intraocular lens with -5.0 diopter power. The patient presented 11 months later with spontaneous haptic disinsertion from the optic. The meniscus (concave-convex) configuration of this iris-fixated lens may have contributed to spontaneous haptic-optic disjunction. This is the first such case reported involving a negative diopter power intraocular lens.
