3.2mm及5.5mm巩膜隧道切口白内障超声乳化术的临床观察

CLINICAL OBSERVATION OF PHACOEMULSIFICATION THROUGH 3.2mm AND 5.5mm SCLERAL TUNNEL INCISION

为评价和比较 ２ 种小切口白内障超声乳化术的临床效果，对 ２ 组 １０７ 例白内障患者施行白内障超声乳化摘除，通过 ３２ｍ ｍ 切口植入硅凝胶折叠式人工晶体和 ５５ｍ ｍ 切口植入 Ｐ Ｍ Ｍ Ａ 硬性人工晶体。结果：３２ｍ ｍ 组术后早期裸眼视力明显优于 ５５ｍ ｍ 组（ Ｐ＜ ０．０５）；角膜散光明显小于 ５５ｍ ｍ 组（ Ｐ＜０．０５）；３ 个月后两组差异无显著性（ Ｐ＞ ０．０５）。两组并发症基本相同，发生率均较低。提示两种小切口白内障超声乳化术均可获得满意的临床效果，但 ３２ｍ ｍ 切口术后散光小，视力恢复快。

To evaluate and compare the clinical results of two scleral tunnel incisions phacoemulsification, 122 eyes of 107 patients with cataract were divided into two groups: phacoemulsification followed by silicone foldable IOLs implantation through 3.2mm incision and PMMA IOLs implantion through 5.5mm incistion. The results showed that eyes in the 3.2mm incision group displayed significantly better uncorrected visual acuity (P<0.05) and less astigmatism (P<0.05)in the early postoperative period. But there were no significant differences in both uncorrected visual acuity and astigmatism three months after surgery (P>0.05). Complications in the two groups were few and comparable. It implied that both procedures of the two scleral tunnel incision offered satisfactory clinical results, but 3.2mm incision surgery allowed singificantly earlier recovery of visual acuity and less corneal astigmation.
