Limbal advancement technique in managing acute or impending peripheral corneal perforations

Abstract

Purpose: To describe the outcomes of a novel technique for the repair of peripheral corneal perforations using autologous limbal tissue. Methods: Two 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. Results: The 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. Conclusion: In conclusion, this technique is a cost-effective and straightforward alternative for the repair of impending acute peripheral perforations.
