Abstract

PURPOSE: We report one case of the sclera-fixated posterior chamber intraocular lens in which haptic fracture developed after rubbing the eye.
METHODS
A 72-year-old man visited our clinic because of diminished vision in his right eye after rubbing the eye. Four years previously, the posterior capsule was ruptured and the nucleus dropped into the vitreous cavity during phacoemusification at another hospital. The patient was transferred to our hospital where vitrectomy, lens nucleus removal and scleral fixation using a PMMA intraocular lens were performed.
RESULTS
The uncorrected visual acuity was finger count 30cm in the right eye and 0.8 in the left eye, and best-corrected visual acuity was 0.6 in the right eye. A dislocated intraocular lens was found at the inferonasal peripheral area in the vitreous cavity. The dislocated intraocular lens was removed through the corneal wound using injection of perfluorocarbon into the vitreous cavity, and then a PMMA intraocular lens with a haptic ring was inserted by scleral fixation. The haptic of the dislocated intraocular lens fixed at the superotemporal region had broken and a rough plane revealed in the electromicroscopic finding. We considered that impact rather than friction caused the haptic to break.
