Abstract
PURPOSE: To describe a method for treating advancing wavelike epitheliopathy (AWE) with liquid nitrogen cryotherapy spray. METHODS: A Brymill liquid nitrogen cryotherapy canister with a "D" tip was used to freeze AWE in 5 cases in 4 patients. Freezing time was approximately 1-2 seconds and was performed twice. The affected limbus and corneal epithelium were treated in this manner. RESULTS: In each case, AWE resolved within 2 weeks, with no recurrence at 1 year. CONCLUSION: Liquid nitrogen cryotherapy is a safe and effective treatment of advancing wavelike epithelopathy.
