部分板层角膜移植治疗角膜皮样瘤疗效观察

Partial lamellar keratoplasty for limba ldermoid

目的评估部分角膜中央板层植片行移植术治疗角膜皮样瘤的疗效。方法2000～2005年，对20例角膜皮样瘤患者实施了部分板层角膜移植术治疗。结果复查初期和晚期的最佳矫正视力分别是0．2、0．6。术前≥6．0D散光度数的患者术后散光度数显著减少。而术前散光度数＜6．0D的患者术后散光度数无明显改变。结论使用部分角膜中央板层植片行移植术治疗角膜皮样瘤能取得好的美容效果，且术后并发症少。

Objective To assess the surgical outcomes in patients who underwent lamellar keratoscleroplasty with partial thickness central corneal grafts for limbal dermoids. Methods Twenty patients undergoing lameilar keratoscleroplasty with partial-thickness central corneal grafts between 2000 and 2005. Results The mean earliest recorded BCVA and the latest postoperative BCVA were 6/30 and 6/10, respectively. Patients with preoperative astigmatism ≥6.0 D were found to have a marked decrease in astigmatism after surgery （ astigmatism change, 5.2 ± 1.7 D）. Patients with preoperative astigmatism 〈6.0 D were found to have an insignificant increase in astigmatism after surgery （astigmatism change, 0. 0 ± 0.6 D）. Conclusions Using partial thickness central corneal grafts in lamellar keratoscleroplasty for limbal dermoids achieved good cosmetic results with limited postoperative complications.
