Late postoperative opacification of multifocal intraocular lens after vitrectomy in a diabetic patient

초록

Purpose: We report a case of late opacity of an AT LISA intraocular lens after vitrectomy in a diabetic patient. Case summary: A 61-year-old man presented with blurring in the left eye. He had undergone bilateral phacoemulsification and intraocular lens implantation 6 years ago, and vitrectomy with SF6 gas tamponade in the left eye due to rhegmatogenous retinal detachment 3 years ago. The patient was diagnosed with pre-existing diabetes, hypertension, and coronary heart disease. Examination of the left eye showed round and centrally located whitish fine granular deposits on the surface of the intraocular lens, and zonular rupture from the 3 to 6 o’clock position. The intraocular lens in the right eye was clear. The corrected vision was 0.9 in the right eye and 0.5 in the left eye. The intraocular lens was explanted from the left eye together with the capsular bag, and was examined under light microscopy, histochemical analysis, and with scanning electron microscopy equipped with an energy dispersive X-ray spectroscopy detector with light element capabilities. Conclusions: This study was the first to report late postoperative opacity in the multifocal intraocular lens, AT LISA 809M. The possibility of intraocular lens opacity in patients with underlying disease or in those undergoing vitrectomy should be explained prior to corrective procedures. © 2019 The Korean Ophthalmological Society
