目的:评价深板层角膜移植治疗圆锥角膜的效果。方法:采用深板层角膜移植术治疗132例140眼圆锥角膜,对其疗效进行观察分析。术后随访6～48mo。结果:术后矫正视力0.2～0.4者13例14眼,～0.8者92例96眼,>0.8者27例30眼,发生排斥反应5眼,植片透明131例139眼,半透明1例1眼,8眼出现后弹力层皱褶。结论:深板层角膜移植术具有并发症少,能减少内皮型排斥反应的发生,术后视力好,且对供体材料要求较低等优点,为治疗圆锥角膜提供了安全有效的选择。

AIM:To evaluate the effect of deep lamellar keratoplasty for the treatment of keratoconus.METHODS:Deep lamellar keratoplasty was applied for treatment of 132 cases (140 eyes) with keratoconus.The effectiveness of operation was clinically observed and evaluated.Postoperative follow-up were 6- 48 months.RESULTS:The postoperative corrected vision was 0.2- 0.4 in 13 cases (14 eyes),>0.4- 0.8 in 92 cases (96 eyes),>0.8 in 27 cases (30 eyes).Rejection occurred in 5 eyes,clear graft in 131 cases (139 eyes),semitransparent in 1 cases (1 eye),8 eyes appeared Descemet’s layer folds.CONCLUSION:Deep lamellar keratoplasty with fewer complications,can reduce the incidence of endothelial rejection.Postoperative visual acuity is good,and there is less demanding on the donor material,etc.It provides a safe and effective choice for the treatment of keratoconus.
