目的：探讨穿透性角膜移植术治疗青少年圆锥角膜的疗效。方法对32例（34眼）青少年晚期圆锥角膜患者进行穿透性角膜移植术治疗，比较术前术后裸眼、针孔以及矫正视力，观察术后屈光状态，并随访18～24个月，评估疗效。结果术后裸眼视力显著提高，针孔视力和矫正视力均高于同期所测裸眼视力，术后12个月以内针孔视力和矫正视力无显著性差异。拆线以后，角膜曲率增加、等效球镜由远视向近视发展、角膜散光值明显减小，矫正视力明显提高。结论穿透性角膜移植术治疗青少年晚期圆锥角膜效果显著；针孔视力可用于术后早期视力评估和随访。

Objective To investigate the clinical effect of penetrating keratoplasty ( PKP) for keratoconus in adolescents.Methods Thirty-two adolescent patients (34 eyes) with advanced keratoconus were treated with PKP.Naked, pin-hole and corrected visual acuity were compared between preoperation and postoperation, refractive state was observed, and then followed up for 18 to 24 months to assess the efficacy.Results The uncorrected visual acuity improved signif-icantly after PKP.Pin-hole and corrected vision were higher than the corresponding uncorrected visual acuity.There was no significant difference between the pin-hole and corrected vision during the first 12 months after PKP.Corneal curvature increased after the sutures removed, the spherical equivalent tended to develop a myopic shift, astigmatism was reduced, and cor-rected visual acuity improved significantly.Conclusion PKP is effective to cure advanced keratoconus in adolescents;pin-hole vision can be used for early postoperative evaluation and follow-up.
