目的 探讨巩膜隧道切口行儿童白内障摘除人工晶体植入术的效果及优点。方法 分别行角巩膜缘梯形切口和巩膜隧道切口 ,对 4 6例 ( 59眼 )儿童外伤性白内障、先天性白内障行白内障摘除人工晶体植入。结果 术后 1周行角巩膜缘梯形切口者和行巩膜隧道切口者矫正视力≥ 0 5者分别占 3 1 % ,76 7% ,术后两周平均散光度分别为 4 2 5± 1 2 5D ,1 50± 0 75D。结论 提示巩膜隧道切口的儿童白内障摘除人工晶体植入术有视力恢复快、散光轻及并发症少的优点。
Objective To investigate the effect and advantages of scleral tunnel incision in children with cataract extraction and intraocular lens implantation. Methods trapezoidal limbus trapezoidal incision and scleral tunnel incision, respectively, 46 cases (59 eyes) children with traumatic cataract and congenital cataract were treated with cataract extraction and intraocular lens implantation. Results One week after operation, the corrected visual acuity ≥ 0 5 was 3.1% and 76.7% respectively in trapezoidal and trabeculectomy patients, and the average postoperative two weeks astigmatism was 42.5 ± 1 2 5D, 1 50 ± 0 75D. Conclusion The scleral tunnel incision pediatric cataract extraction with intraocular lens implantation has the advantages of rapid visual recovery, less astigmatism and fewer complications.
