The charts of 8 consecutive patients(mean age: 13.0 y) 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 log MAR 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.展开更多
