Limbal advancement technique in managing acute or impending peripheral corneal perforations

Abstract

PurposeTo describe the outcomes of a novel technique for the repair of peripheral corneal perforations using autologous limbal tissue. MethodsTwo patients with peripheral corneal perforations with contraindications to other corneal procedures underwent limbal advancements. This technique involves creating a pedicle of the limbus, sclera and conjunctiva to cover the perforation. ResultsThe tissue had optimal integration in both patients; no aqueous leaks or flat anterior chambers were noted. None of the patients had recurrence of perforation or ocular discomfort. ConclusionIn conclusion, this technique is a cost-effective and straightforward alternative for the repair of impending acute peripheral perforations.
