The charts of 8 consecutive patients （mean age： 13.0y） who had undergone limbal dermoid excision with lamellar corneosclerai 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 IogMAR 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
