在一项前瞻性随机临床试验中，我们比较了两组患者(38例)采用两种不同缝合技术的穿透性角膜移植后的散光。第一组(18例)采用24咬合10-0尼龙线(单流线)，术后调整缝线以减少散光。第二组(20例)采用16咬合10-0尼龙线和8条间断10-0尼龙线(联合10-0尼龙线和间断尼龙线)的组合，术后选择性地拆除间断线以减少散光。单线运行缝线的散光度低于单线运行加间断缝线(单线运行+间断缝线，2.7+/-2.2度数；联合运行+中断线，3.9+/-2.5度；P<；0.02)。两组的平均随访期相似(单行缝合9.0+/-2.2个月，联合缝合+间断缝合8.4+/-2.2个月)。两组患者的最短随访时间均为6个月。无一例流动缝线断裂。在穿透性角膜移植术后，可调单次移动缝线技术比16咬合移动缝线和8条间断缝线相结合的技术提供了更好的散光控制。
In a prospective randomized clinical trial we compared astigmatism after penetrating keratoplasty with two different suture techniques between two groups of patients (38 patients). The first group (18 patients) had a 24-bite single running 10-0 nylon suture (single running suture) with postoperative suture adjustment to decrease astigmatism. The second group (20 patients) had a combination of a 16-bite running 10-0 nylon suture and eight interrupted 10-0 nylon sutures (combined running and interrupted sutures) with selective postoperative removal of interrupted sutures to decrease astigmatism. The single running suture resulted in a lower postoperative astigmatism than a combined running and interrupted suture technique (single running suture, 2.7 +/- 2.2 diopters; combined running and interrupted sutures, 3.9 +/- 2.5 diopters; P < .02). Average length of follow-up was similar in both groups (single running suture, 9.0 +/- 2.2 months and combined running and interrupted sutures, 8.4 +/- 2.2 months). Minimal length of follow-up was six months in both groups. No running sutures were broken. The adjustable single running suture technique provided greater control of astigmatism after penetrating keratoplasty than a technique using a combination of a 16-bite running suture and eight interrupted sutures.
