Optical transparency of the intraocular lens (IOLs) is paramount in maintaining visual improvement after cataract extraction. There have been reports of the IOL developing opacity after years of cataract surgery. IOL opacities have been reported in silicone, acrylic lens, and very rarely in polymethylmethacrylate (PMMA) IOLs. Though the exact cause is not known, long-term exposure to ultraviolet light can be one of the most probably causes, leading to disruption of PMMA and release of gaseous (nitrogen) within the PMMA substance. We report one such rare case of PMMA IOL opacity in a 75-year-old female. |
