Many patients with high-grade corneal astigmatism cannot tolerate correction with spectacles or contact lenses. In contrast to myopic patients, in these cases visual rehabilitation can only be achieved surgically. In 1990 we started to perform modified corneal T-incisions in cases with high-grade astigmatism and intolerance to glasses or contact lenses. According to the eligibility criteria for selection of patients only 12 eyes were operated on in 1990: 9 eyes were affected by congenital high-grade astigmatism (mean 5.25 D); 1 had 8.5 D astigmatism after perforating injury, keratoplasty and cataract operation; 1 had 2.5 D astigmatism after perforating injury; and 1 eye showed 5.0 D astigmatism following cataract surgery. Without exception, the astigmatism was significantly reduced, from a preoperative mean of 5.25 D to a mean of 2.0 D postoperatively. The most impressive change was the improvement of uncorrected visual acuity. No complications were observed and none of the patients complained of postoperative glare. These results have encouraged us to continue with surgical correction of high-grade corneal astigmatism.
许多高度角膜散光患者无法耐受眼镜或隐形眼镜矫正。与近视患者不同，在这些情况下，视力康复只能通过手术实现。1990年，我们开始对高度散光且不耐受眼镜或隐形眼镜的患者进行改良角膜T形切口手术。根据患者选择的入选标准，1990年仅有12只眼睛接受了手术：9只眼睛患有先天性高度散光（平均5.25 D）；1只眼睛在穿孔伤、角膜移植和白内障手术后有8.5 D散光；1只眼睛在穿孔伤后有2.5 D散光；1只眼睛在白内障手术后有5.0 D散光。无一例外，散光显著降低，术前平均为5.25 D，术后平均为2.0 D。最显著的变化是未矫正视力的提高。未观察到并发症，且没有患者抱怨术后眩光。这些结果鼓励我们继续进行高度角膜散光的手术矫正。
