摘要
目的 探讨超声乳化术中不同形式切口对视力和散光的影响。方法 １１０例１１０只眼白内障随机分为５．５ｍ ｍ 直线式或眉状巩膜隧道切口。除创口形状外，每例都做相同的手术，裸眼视力和散光分析至术后３ｍ ｏ。结果 术后１ｗ ｋ 和３ｍ ｏ 视力≥０．５者，在直线切口组分别为３４ 眼（６４．３％ ）和４６眼（８２．２％ ），在眉状切口组分别为３５ 眼（６４．９％ ）和４４ 眼（８１．５％ ），２组差异无显著性（Ｐ＞ ０．１０）；２组“反规则”的角膜散光在术后３ｍ ｏ 分别为－ ０．３０±０．７５Ｄ和－ ０．３０±０．７０Ｄ，差异也不显著（Ｐ＞ ０．１０）。结论 超声乳化术中，５．５ｍ ｍ 直线式或眉状不同的巩膜隧道切口对患者术后视力和角膜散光并无明显的影响。
Objective To evaluate the impact of different incisions on visual acuity and astigmatism in phacoemulsification. Methods One hundred and ten eyes of 110 patients with cataract were randomly assigned to either a 5.5mm straight or frown shaped scleral tunnel incision procedure. Identical surgical methods were used in all cases with different incisions. Data on uncorrected visual acuity and induced astigmatism had been analyzed for three months after the surgeries. Results At the 1st week and the 3rd month, postoperative visual acuity showed 0.5 or better in 34 eyes (64.3%) and 46 eyes(82.2%)in the group of straight incision, and 35 eyes(64.9%) and 44 eyes(81.5%) in the group of frown shaped incision respectively. The difference was not significant (P>0.10). The 'against the rule”corneal astigmatism in both groups at the third month showed -0.30± 0.75 D and -0.30±0.70D respectively. The difference was not significant either(P> 0.10 ). Conclusion Different shapes of incisions mentioned above do not affect postoperative visual acuity and corneal astigmatism significantly.
