Abstract

PURPOSE

We report preliminary results of a new procedure for correcting high astigmatism after penetrating keratoplasty.

METHODS

The procedure entails full-thickness trephination along the original donor-recipient junction with careful suturing in a combined interrupted and running fashion. Four eyes of four patients with severe astigmatism and myopia after penetrating keratoplasty underwent the procedure.

RESULTS

High preoperative cylinder ranging from 4.50 to 16.00 D (mean 9.00 D) was reduced to 0.50 to 3.50 D (mean 1.90 D) at the last examination (between 3 to 6 months). Spherical equivalent myopia ranging from -2.00 to -10.25 D (mean -4.90 D) was essentially unchanged at plano to -9.00 D (-4.70 D) at the last examination. Overall, there was a mean refractive cylinder reduction of 7.10 D (79%).

CONCLUSION

Retrephination after penetrating keratoplasty appears to be an acceptable alternative for correcting high astigmatism, and had only a small effect on the level of myopia.

摘要

目的

我们报告一种穿透性角膜移植术后矫正高度散光新方法的初步结果。

方法

该方法需要沿着原来的供体-受体界面进行全层环钻，并采用间断与连续相结合的方式仔细缝合。4例穿透性角膜移植术后患有严重散光和近视的患者的4只眼睛接受了该手术。

结果

术前高达4.50至16.00 D（平均9.00 D）的柱镜度数在最后一次检查时（3至6个月之间）降至0.50至3.50 D（平均1.90 D）。术前-2.00至-10.25 D（平均-4.90 D）的等效球镜近视度数在最后一次检查时基本未变，变为平光至-9.00 D（-4.70 D）。总体而言，平均屈光柱镜度数降低了7.10 D（79%）。
