深板层角膜移植术治疗圆锥角膜疗效观察

Efficacy observation of deep lamellar keratoplasty for the treatment of keratoconus

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.
