Postoperative astigmatism is one of the major limitations of penetrating keratoplasty. In an attempt to reduce postkeratoplasty astigmatism, we combined corneal-relaxing incisions with orthogonal compression sutures, guided by the intraoperative use of a ring keratometer. Eleven consecutive patients from a mixed referral population with functionally disabling astigmatism were studied. The average preoperative keratometric cylinder of 11.68 diopters was reduced by 7.95 (+/- 3.03 SD) diopters. Each patient's net keratometric cylinder was reduced. We believe that this technique is safer and more predictable than previously published techniques.
术后散光是穿透性角膜移植术的主要局限性之一。为了减少角膜移植术后的散光，我们在术中使用环形角膜曲率计的引导下，将角膜松解切口与正交压迫缝线相结合。对11例来自混合转诊人群、患有功能性致残散光的连续患者进行了研究。术前平均角膜曲率计圆柱度为11.68屈光度，降低了7.95（±3.03标准差）屈光度。每位患者的净角膜曲率计圆柱度均有所降低。我们认为，与先前发表的技术相比，这项技术更安全、更可预测。
