Corneal transplants were performed in 50 eyes using eight deeply placed interrupted 24 micron (10--0) monofilament nylon sutures followed by a more superficial continuous 16 micron (11--0) monofilament nylon suture placed around the wound in 16 equal bites. After surgery the 24 micron sutures in the steepest corneal meridian based on central and peripheral keratometry were cut. This suture technique permitted the donor cornea to assume its normal shape more rapidly while reducing the induced postkeratoplasty astigmatism. With this technique corneal astigmatism was reduced an average of 3.4 diopters (range 0--10 diopters), which allowed patient to achieve a mean visual acuity at three months of 20/50 and at 11 to 13 months of 20/35. Although this suture technique does not eliminate postkeratoplasty astigmatism, it permits the surgeon to reduce actively high degrees of astigmatism present after corneal transplantation.
对50只眼睛进行了角膜移植，使用8根置于深层的间断24微米（10 - 0）单丝尼龙缝线，然后在伤口周围以16等份的间距放置一根较浅的连续16微米（11 - 0）单丝尼龙缝线。术后，根据中央和周边角膜曲率测量，在角膜最陡子午线处的24微米缝线被剪断。这种缝合技术使供体角膜能更快恢复其正常形状，同时减少角膜移植术后诱发的散光。采用这种技术，角膜散光平均降低了3.4屈光度（范围为0 - 10屈光度），这使得患者在术后三个月时平均视力达到20/50，在11至13个月时达到20/35。虽然这种缝合技术不能消除角膜移植术后的散光，但它使外科医生能够有效降低角膜移植后出现的高度散光。
