Localized edema with soft toric contact lenses.

Soft toric contact lenses had provided a good correction for this patient for 3 1/2 years. An acute episode of slightly decreased vision and lens discomfort was accompanied by corneal irritation, edema, irregular distorted keratometric mires, and a change in refractive cylinder. It is of interest that the areas of most corneal disturbance were in continuous apposition to the areas of most deposits on the non-rotating toric contact lenses.
