SUFFICIENT time has elapsed and enough additional patients have been fitted with the corneal lens to warrant a second report.1 Approximately 600 patients have been fitted to date, and the results are promising. The Tuohy corneal lens2 appears to have established itself as another mechanical aid to vision.
