Epikeratophakia provides a permanent optical correction for aphakia in children with congenital or traumatic cataracts; suturing the epikeratophakia graft onto the cornea eliminates the problems of contact lens or spectacle non-compliance in these young and generally uncooperative patients and provides tectonic support to scarred and irregular corneas. Eighteen children under the age of six years underwent epikeratophakia for the correction of aphakia after the removal of trauma-induced cataracts. Graft success rate was 88%; the average change in keratometry in the patients with successful grafts was 14.82 +/- 2.0 diopters. In the 13 patients eligible for visual acuity tabulation, preoperative acuities ranged from light perception to 20/200, and postoperative acuities ranged from hand motions to 20/30. Ten (77%) had acuities of 20/80 or better. Poor results in three patients with less than 20/200 acuities were likely the results of non-compliance with amblyopia therapy. Present work indicates that in cases of traumatic cataract, the epikeratophakia procedure facilitates amblyopia therapy and decreases the astigmatism in scarred and irregular corneas.
表层角膜镜片术为患有先天性或外伤性白内障的儿童无晶状体眼提供了永久性的光学矫正；将表层角膜镜片术移植物缝合到角膜上，消除了这些年幼且通常不合作的患者中隐形眼镜或眼镜佩戴不依从的问题，并为瘢痕化和不规则的角膜提供了结构支持。18名6岁以下儿童在摘除外伤性白内障后接受了表层角膜镜片术以矫正无晶状体眼。移植物成功率为88%；移植物成功的患者角膜曲率计平均变化为14.82±2.0屈光度。在13名符合视力制表条件的患者中，术前视力从光感至20/200不等，术后视力从手动至20/30不等。10名（77%）患者的视力达到20/80或更好。3名视力低于20/200的患者效果不佳，可能是由于不依从弱视治疗所致。目前的研究表明，在外伤性白内障病例中，表层角膜镜片术有助于弱视治疗，并减少瘢痕化和不规则角膜中的散光。
