目的：比较前房内注入肾上腺素联合利多卡因和应用瞳孔扩张器两种方式处置虹膜松驰综合征（IFIS）的有效性。方法43例（43只眼）发生IFIS患者中，25例采用前房内注入0．1％肾上腺素联合0．5％利多卡因处置，18例采用瞳孔扩张器处置，观察虹膜涌动、瞳孔缩小及虹膜脱出的改善程度。结果25例IFIS患者采用前房内注入0．1％肾上腺素联合0．5％利多卡因处置，仅9例（36．0％）恢复瞳孔扩张状态，其中11例虹膜脱出者中仅2例（18．2％）未再发生虹膜脱出；18例IFIS患者采用瞳孔扩张器处置，均恢复瞳孔扩张状态（100．0％），其中8例虹膜脱出者仅1例（12．5％）术中未再发生虹膜脱出。结论前房内注入肾上腺素联合利多卡因不能有效阻止IFIS的发生，对手术操作帮助不大；瞳孔扩张器能有效阻止虹膜涌动及瞳孔缩小，降低手术难度，但不能有效防止虹膜脱出，应特别注意。

Objective To compare the effects of anterior chamber injection of lidocaine 0.1% and epinephrine 0.5%( ILE) versus conventional pupil dilator on intraoperative floppy iris syndrome ( IFIS) .Methods Two methods were employed to manage 43 eyes presented with IFIS .Twenty-five of 43 eyes were treated with ILE and 18 of 43 eyes were man-aged with pupil dilator .Presence of pupil constriction , billowing iris and iris prolapse was compared between the two groups of patients.Results In 25 eyes treated with ILE, nine (36.0%) showed sustained pupillary dilatation .There were 11 eyes presented with iris prolapse in this group , and iris restored in only 2 eyes (18.2%).In contrast, in 18 eyes managed with pupil dilator , all maintained pupil dilation during the surgery .There were 8 eyes presented with iris prolapse , and iris restored in only one (12.5%) eye.Conclusions ILE is ineffective in most IFIS cases .Pupil dilator is the most reliable means of maintaining a safe pupil diameter during cataract surgery .However, pupil dilator could not prevent iris prolapse .
