Spontaneous fracture of an intraocular lens (IOL) haptic is a rare complication of cataract surgery. The authors report a case of spontaneous fracture of an implanted posterior chamber IOL. CASE. CASE. Five years ago, a 12-year-old patient underwent linear lens extraction, posterior capsulotomy, and anterior vitrectomy due to traumatic cataract and received a polymethyl methacrylate (PMMA) biconvex posterior chamber IOL implanted in ciliary sulcus. Five years later, IOL optic was found in anterior chamber with its haptics broken from the optic-haptic junction. DISCUSSION. The broken haptic was examined with scanning electron microscopy. The fracture site of the haptic was on the optic-haptic junction. The fractured surface had a regular appearance. DISCUSSION. The broken haptic was examined with scanning electron microscopy. The fracture site of the haptic was on the optic-haptic junction. The fractured surface had a regular appearance. CONCLUSIONS. To our knowledge, this is the fourth report of spontaneous fracture of an implanted posterior chamber IOL.eninfo:eu-repo/semantics/closedAccessSpontaneous FracturePosterior Chamber Intraocular LensSpontaneous fracture of an implanted posterior chamber intraocular lensSpontaneous fracture of an implanted posterior chamber intraocular lensArticle154507509WOS:0002305109000162-s2.0-238445444671600138710.1177/112067210501500416Q2Q4
