Abstract

Empirical fitting of a bitoric rigid gas permeable contact lens for the management of a scarred irregular cornea caused by herpes zoster ophthalmicus is described. Two corneal scars, which affect the pupil axis, caused an irregular cornea and produced low visual acuity and anisometropia. Two contact lenses were necessary to complete the fitting. Visual acuity improved from 0.2 to 1.0. The rigid gas permeable lenses can be a good alternative in the management of patients with irregular corneas caused by herpes zoster ophthalmicus.
