title: Visual distortion after myopic keratomileusis: computer analysis of keratoscope photographs.
abstract: A patient experienced marked visual distortion following myopic keratomileusis, despite the presence of a clear graft and an apparently smooth corneal surface. A color coded topographic map of corneal surface power generated by computer analysis of a keratoscope photograph of the operated eye identified a degree of irregular astigmatism and asphericity not readily apparent from simple visual inspection of the keratoscope photograph. Contour map graphics display of corneal surface power is a useful clinical tool in the evaluation of visual distortion complications following myopic keratomileusis.
