The Preliminary Report of Epikeratophakia in the Treatment of Pediatric Aphakia after Traumatic Cataract Extraction

Purpose: To study the role of epikeratophakia in treating pediatric unilateral aphakia after traumatic cataract extraction.Methods: We performed epikeratophakia in 43 children to treat aphakia after traumatic cataract extraction, using the corneal lenses made by ourselves. The rehabilitation of the the postoperative vision and the prevention of amblyopia were observed with a mean follow-up period of 20 months.Results: All the lenses remained transparent. Postoperatively, 31 cases (72. 1%) achieved uncorrected visual acuities (V. A) over 0. 2, 32 cases (74. 4%) achieved corrected V. A over 0. 4. Most of the cases achieved the best preoperative corrected V. A with spectacles of less than 3 diopters. No severe complication occurred. Conclusion: Epikeratophakia is predictable with quality lens and correct surgical technique. The result suggests that the epikeratophakia is one of the best treatment for the pediatric aphakia especially for those who are not optimal for IOL implantation. Eye Science 1997 ;

表面角膜镜片术治疗小儿外伤性白内障术后无晶体眼的初步报告

用自制的同种材料的表面角膜镜片，对４３例（４３只眼）小儿外伤性白内障术后无晶体眼施行手术治疗，追踪时间平均２０个月，结果全部镜片透明愈合。有３１例（７２．１％）术后裸眼视力达０．２以上，３２例（７４．４％）矫正视力达０．４以上。大部分病例加戴３Ｄ以下的眼镜可达术前的矫正视力，无严重并发症。表明：表面角膜镜片术是治疗小儿外伤性白内障术后无晶体眼的最好办法之一，尤其适用于不能装人工晶体的病例。

表面角膜镜片术治疗儿童无晶体眼12例临床分析

采用计算机数据处理和自制冷冻车床加工角膜组织镜片，为１２例７～１４岁的单眼外伤性白内障患儿行表面角膜镜片术。经８～３２个月随访，平均屈光度增加１１．２１Ｄ；８例裸眼视力达４．２～４．４，≥４．５者４例；矫正视力达４．７者３例，≥４．８者９例，均较术前提高。一次手术成功率为９１．６７％（１１／１２），术后散光度平均增加２．５Ｄ。
