An evaluation of clinical and pateitn acceptance of the Dow Corning silcon hard resin contact lenses

1 March 1983

Abstract

The purpose of this study was to determine the clinical and patient acceptance of the Dow Corning SILCON hard resin lens. Ten subjects were initially used for this study. After three months of wear, the lenses showed superior wettability, consistent visual acuities, and no clinically significant edema. Subjective patient comfort was good with a few intermittent reports of a scratchy or itchy feeling of the eyes. These symptoms Here found to be relieved by a thorough recleaning of the lenses.

Because of the lens surface alteration, ·these lenses cannot be modified or polished. This created a. problem .with turn around time for lenses that needed to be refit or modified.
