Microfiltered 3% hydrogen peroxide (H2O2) solutions have become increasingly popular as disinfectants for soft contact lenses. We report a case in which an aphakic soft contact lens stored for a week in a 3% H2O2 solution (30 000 ppm) and inserted without neutralization caused a reversible corneal opacity.
Report of a Case.
—An 85-year-old woman without a history of blepharitis or dry eye had undergone a penetrating keratoplasty with an extracapsular cataract extraction and posterior chamber lens implantation in the left eye for Fuchs' corneal dystrophy 8 years earlier. Five months later, she developed a traumatic wound dehiscence requiring intraocular lens removal and anterior vitrectomy, resulting in a final visual acuity of 20/200 OS. Postoperatively, the graft remained clear, with an epithelium that appeared to be normal and a corneal thickness of 0.64 mm. Recently, the patient presented for reinsertion of her aphakic
