PURPOSE: We describe 8 cases of late spontaneous in-the-bag intraocular lens (IOL) luxation into the vitreous cavity, which occurred at the Department of Ophthalmology and Neurosurgery of the University of Siena between January and December 2006. METHODS: In this interventional case series, the medical records of all patients with posterior luxation of in-the-bag IOLs - who had undergone a pars plana vitrectomy with IOL removal and scleral fixation IOL implantation between January and December 2007 at the Department of Ophthalmology and Neurosurgery of Siena, Italy - were retrospectively reviewed. RESULTS: The final post- operative visual acuity was 20/30 or better in 6 patients, while myopic macular degeneration and total retinal detachment limited visual acuity in the remaining 2 patients. CONCLUSION: The high prevalence of pseudoexfoliation (PEX) in the patients who had been operated for cataract phacoemulsification in our department could explain the occurrence of 8 posterior luxations of in-the-bag IOLs in only 1 year. Our study suggests that for the next years we will expect an increase in occurrence of spontaneous in-the- bag IOL luxations in the vitreous cavity. This condition could represent the last stage of PEX syndrome.

Abstract

PURPOSE: We describe 8 cases of late spontaneous in-the-bag intraocular lens (IOL) luxation into the vitreous cavity, which occurred at the Department of Ophthalmology and Neurosurgery of the University of Siena between January and December 2006. METHODS: In this interventional case series, the medical records of all patients with posterior luxation of in-the-bag IOLs - who had undergone a pars plana vitrectomy with IOL removal and scleral fixation IOL implantation between January and December 2007 at the Department of Ophthalmology and Neurosurgery of Siena, Italy - were retrospectively reviewed. RESULTS: The final post- operative visual acuity was 20/30 or better in 6 patients, while myopic macular degeneration and total retinal detachment limited visual acuity in the remaining 2 patients. CONCLUSION: The high prevalence of pseudoexfoliation (PEX) in the patients who had been operated for cataract phacoemulsification in our department could explain the occurrence of 8 posterior luxations of in-the-bag IOLs in only 1 year. Our study suggests that for the next years we will expect an increase in occurrence of spontaneous in-the- bag IOL luxations in the vitreous cavity. This condition could represent the last stage of PEX syndrome.
