Eighteen eyes with wound dehiscence after penetrating keratoplasty were studied. Keratoplasty was performed for corneal scarring (n = 8), dystrophies (n = 6), graft failure (n = 2), and corneal edema (n = 2). The mean duration between keratoplasty and wound dehiscence was 6.54 months. All eyes underwent wound repair with or without iris excision, lensectomy, and vitrectomy. Grafts remained clear in eight eyes. Five eyes developed phthisis bulbi. Visual acuity was better than 20/200 in seven eyes. There was no site (quadrant) specificity for dehiscence. Trivial trauma resulted in dehiscence in 10 of the 18 eyes. The major determinants of visual outcome were the force of trauma and status of the posterior segment. Dehiscence of the graft-host junction in all cases reflects its persistent weakness after surgery.
对18只穿透性角膜移植术后发生伤口裂开的眼睛进行了研究。角膜移植手术的原因包括角膜瘢痕（n = 8）、营养不良（n = 6）、移植失败（n = 2）和角膜水肿（n = 2）。角膜移植术与伤口裂开之间的平均间隔时间为6.54个月。所有眼睛均接受了伤口修复，部分伴有虹膜切除术、晶状体切除术和玻璃体切除术。8只眼睛的移植片保持透明。5只眼睛发生眼球痨。7只眼睛的视力优于20/200。伤口裂开无部位（象限）特异性。18只眼睛中有10只因轻微外伤导致伤口裂开。视力结果的主要决定因素是外伤的力度和眼后段的状况。所有病例中移植片与宿主交界处的裂开反映了手术后该处持续存在的薄弱。
