Abstract
To the Editor. —Photic retinal damage has been shown to be associated with exposure to the light from the operating microscope in aphakic, phakic, or pseudophakic eyes, even in the presence of an ultraviolet filter.1,2 I wish to describe a patient who suffered photic retinal damage during an extracapuslar cataract extraction with posterior lens insertion that resulted in profound visual acuity loss (20/400), noted the first day postoperatively and persisting for four weeks. The patient's visual acuity eventually returned to 20/20, but she was left with a paracentral scotoma and macular dysfunction such that exposure to a bright light would cause a marked loss of acuity that would persist for many minutes. Method. —The operation was performed using a Week model 1206 ceiling-mounted microscope with coaxial fiberoptic illumination, fitted with an ultraviolet filter (Edward Weck and Co Inc, Research Triangle Park, NC). Illumination at the operative setting was 13000
