Keratometric Reflexes on Flexible Lens Surfaces

The quality of the keratometric mire reflection is evaluated and related to acuity, corneal edema, comfort and lens acceptance in this study of 800 eyes. A method of classifying distortion is described. When the observer notes such irregularity, several conditions are more likely to occur: the lens will exhibit toricity, vision may not be acceptable to the patient even though acuity is 20/20, and there is a slight but significant probability that the patient will be more uncomfortable while wearing the lens. No significant reliable relationship could be shown between corneal edema and visual acuity nor between lens surface irregularity and edema. More than three fourths of the patients with measurable astigmatism in excess of 1.00 D had acuity better than 20/25.
