Lamellar keratoplasty with corneoscleral graft for limbal dermoids

Abstract

To assess the postoperative outcomes of limbal dermoid excision with corneoscleral graft transplantation. The charts of 8 consecutive patients (mean age: 13.0y) who had undergone limbal dermoid excision with lamellar corneoscleral graft transplantation by a single surgeon were retrospectively reviewed. Mean dermoid size was 7.75 mm (6.0-12.0 mm). Mean visual acuities (in logMAR units) before and after surgery were 1.8 and 1.7, respectively (P=0.29). Spherical equivalents were 1.3 diopter (D) before surgery and 0.7 D after surgery (P=0.40). The mean astigmatism measurements before and after surgery were 2.4 D and 1.5 D, respectively (P=0.17). Vector analysis revealed a mild change in astigmatism with a mean “d” of 3.2 (0.56-6.89). No intra- or post-operative complications occurred. Lamellar keratoplasty for limbal dermoids is safe and offers good cosmesis and tectonic stability. A significant decrease in the amount of astigmatism is not expected following surgery.
