【摘要】 目的 评价经角巩膜隧道切口的白内障超声乳化摘除及折叠式人工晶体植入手术的方法和疗效。方法 在上方角巩缘做3.2 mm梯形隧道切口，对103例(110只眼)老年性、并发性、先天性和外伤性白内障行超声乳化摘除，并植入HEMA折叠式人工晶体。结果 术后1天裸眼或球镜矫正视力≥0.5者占90.0％；术后1周，1个月和3个月视力≥1.0者分别为42.5％，63.7％，68.0％。术后1周平均散光为（1.00±0.68）D，仅比术前增加0.07D(P＞0.05)。术后1个月和3个月平均散光分别为（0.91±0.55）D和（0.83±0.57）D，与术前亦无统计学差异(P＞0.05)。与巩膜隧道切口组和透明角膜隧道切口组散光比较，结果基本相同。结论 提示角巩缘隧道切口的超声乳化和折叠式人工晶体植入，与巩膜隧道切口和透明角膜切口一样具有术后早期恢复和稳定眼屈光状态及视力的优点，但同时能克服巩膜和角膜隧道切口手术的不足之处。

【Abstract】 Objective To advance and evaluate the technique and therapeutic effects of phacoemulsification with foldable intraocular lens implantation through a limbus tunnel incision.Methods The surgery was performed through a 3.2 limbus tunnel incision on 110 eyes of 103 patients with senile, complicated, congenital and traumatic cataracts.Results Postoperatively, the visual acuities with spherical correction or without correction were 0.5 or better in 90.0% of the eyes at one day , and 1.0 or better in 42.5%, 63.7% and 68.0% at one week, one month and three months respectively. The mean postoperative astigmatism was (1.00±0.68) D at one week and only 0.07D more than the mean preoperative one (P＞0.05). There was also no statistical difference between the mean preoperative astigmatism and postoperative astigmatism at one and three months, which were respectively (0.91±0.55) D and (0.83±0.57) D. The mean postoperative astigmatism was almost the same as compared between the scleral tunnel incision and clear corneal incision groups.ConclusionThe phacoemulsification with foldable intraocular lens implantation through a limbus tunnel incision can reduce postoperative astigmatism and shorten the period of visual rehabilitation as the operation through a scleral tunnel or a clear corneal incision, and in the mean time the former method can overcome the shortages of the latter two methods.

自Fine（1992）报告透明角膜切口的白内障超声乳化手术新技术后，因其不仅具有与巩膜隧道切口一样的术后散光小、视力恢复快等优点，而且手术更为便捷，故受到国内外广泛的接受和应用，从而使超声乳化手术进入规模化手术时代［1-4］。但透明角膜切口因无结膜瓣覆盖，存在潜在感染的可能性一直倍受关注；另外，手术时发生玻璃体溢出需要扩大切口时，缝线暴露等缺点也不能忽视［5］。我们通过对比和实践了巩膜和角膜切口的超声乳化手术后，于1997年9月提出并开展了角巩缘隧道切口的白内障超声乳化摘除及折叠式人工晶体植入手术，现将初步结果和经验介绍如下。
