Results of a clinical study concerning 40 consecutive cases of high post-keratoplasty astigmatism corrected by the transverse keratotomy technique are presented and analysed. The protocol was determined for each case by keratometry and a qualitative analysis of the anterior corneal topography. The mean preoperative cylinder was 8.60 +/- 2.31 D. The mean postoperative cylinder was 4.79 +/- 1.82 D. The mean cylinder change was 4.40 +/- 2.92 D. In a majority of cases the corrected visual acuity (for distance and reading vision) was improved. There was no change in the spherical equivalent value. The main drawback of the procedure is its poor predictability. The procedure is effective in this indication and relatively safe.
本文呈现并分析了一项关于连续40例采用横向角膜切开术矫正角膜移植术后高度散光的临床研究结果。通过角膜曲率计和对角膜前表面地形图的定性分析为每个病例确定方案。术前平均柱镜度数为8.60±2.31D。术后平均柱镜度数为4.79±1.82D。平均柱镜度数变化为4.40±2.92D。在大多数病例中，矫正视力（远视力和近视力）得到改善。球镜当量值无变化。该手术的主要缺点是其预测性较差。该手术在这一适应症中有效且相对安全。
