To assess the outcome of transverse keratotomy to correct high corneal astigmatism after cataract surgery.
Vall d'Hebron Hospital, Department of Ophthalmology, Cornea and Refractive Surgery Unit, Barcelona Autónoma University, Spain.
Thirty-two eyes with regular corneal astigmatism between 2.50 and 5.00 diopters (D) after previous cataract surgery had two transverse incisions with an optical zone of 5.0 or 7.0 mm, a depth of 80 or 90%, and a length of 3.0 or 4.0 mm, depending on the amount of astigmatism and based on a personal nomogram we developed.
From 80 to 100% of the desired correction was achieved in 38.7% of eyes and from 60 to 80% in 38.9%. At 6 months, only 9.1% had a keratometric change of more than 0.50 D. Best corrected visual acuity was the same or better in 85.2% of patients; no patient lost more than one Snellen line.
This easy, safe technique had low anatomical and refractive morbidity and high efficacy, making it an excellent option for eyes with high astigmatism after cataract surgery. More research is required in view of the considerable unpredictability of our results and the disparity in methods and results of other published studies.
评估白内障手术后行横向角膜切开术矫正高度角膜散光的效果。
西班牙巴塞罗那自治大学瓦尔德希伯伦医院眼科角膜与屈光手术科。
32只曾接受白内障手术、角膜规则散光在2.50至5.00屈光度（D）之间的眼睛，根据散光量并基于我们制定的个人列线图，进行了两条横向切口，光学区为5.0或7.0毫米，深度为80%或90%，长度为3.0或4.0毫米。
38.7%的眼睛实现了80%至100%的预期矫正，38.9%的眼睛实现了60%至80%的预期矫正。6个月时，仅9.1%的眼睛角膜曲率计变化超过0.50 D。85.2%的患者最佳矫正视力相同或更好；没有患者视力下降超过一行。
这种简单、安全的技术具有较低的解剖和屈光并发症发生率以及较高的疗效，使其成为白内障手术后高度散光眼的极佳选择。鉴于我们结果的相当大的不可预测性以及其他已发表研究的方法和结果的差异，需要更多的研究。
