目的：观察扭动式超声乳化对白内障术后黄斑中心凹视网膜厚度及角膜的影响。 　　方法：采用常规式超声乳化和扭动式超声乳化进行白内障手术,选取术中无并发症发生的单纯性老年性白内障52例52眼,随机分入观察组(扭动式超声组,26眼)和对照组(常规超声组,26眼),于术后1,4,12 wk行光学相干断层成像术(OCT)测量黄斑中心凹视网膜厚度,术后1d裂隙灯观察角膜水肿情况。 　　结果：观察组和对照组黄斑中心厚度在术后1,4,12 wk时均较相应组术前值增加(P<0.05)；两组间在术后1wk时黄斑厚度增加差异明显(P<0.05),4,12wk时两组间无明显差异(P>0.05)。术后观察组对角膜水肿的影响较小(P<0.05)。 　　结论：扭动式超声乳化手术相对常规超声来说对眼角膜及黄斑中心凹视网膜的影响都较小,能有效地减轻术后反应。

AIM: To report the influences onfoveal thickness and corneal edema after torsional phacoemulsification. METHODS: Totally 52 patients ( 52 eyes ) with age-related cataract were randomly assigned to phacoemulsification using torsional mode ( 26 eyes ) or conventional ultrasound mode ( 26 eyes ) . The foveal thickness examined by optical coherence tomography (OCT) after surgery at 1, 4 and 12wk and corneal edema was examined by slit lamp after surgery at 1d. RESULTS: The postoperative averagefoveal thickness datas of the two groups, comparing with corresponding preoperative datas, were significantly augmented at 1, 4 and 12wk (P<0. 05);the difference of foveal thickness was obviously augmented at 1wk postoperatively (P<0. 05), was no obvious differences at 4 and 12wk(P>0. 05). The effects of corneal edema in torsional group were slighter (P<0. 05). CONCLUSION: The postoperative influences onfoveal thickness and corneal edema with torsional mode are slighter than that with ultrasound mode, and the postoperative reactions with torsional mode are efficiently reduced.
