目的　探讨前葡萄膜炎小瞳孔并发白内障行超声乳化吸出术的临床效果。方法　对 41例 43眼前葡萄膜炎小瞳孔并发白内障患者行超声乳化白内障摘除联合人工晶体植入术。采用三种方法扩大瞳孔 :① 19眼行机化膜剪除联合放射状瞳孔松解术 ;② 11眼行直接牵拉扩张瞳孔 ;③ 13眼单纯分离粘连 ,用粘弹剂扩张瞳孔。结果　术后瞳孔均保持 3～ 3 5mm圆形 ,无粘连 ,具有一定活动度。术后视力 :术后 1周≥ 0 5占 62 8% ,术后 1个月≥ 0 5占 69 9%。并发症 :后囊破裂 2眼 (4 7% ) ,角膜水肿 6眼 (13 9% ) ,3～ 5d水肿消失 ,虹膜睫状体炎 1眼 (2 3 % )。结论　超声乳化术治疗葡萄膜炎小瞳孔并发白内障是安全有效的 ,可获得良好的术后视力 ,且瞳孔圆形 ,是对眼内组织损伤最小的理想术式 Objective To investigate the clinical effect of phacoemulsification with small pupil of cataract and anterior uveitis. Methods 41 cases of 43 anterior uveitis with small pupil cataract patients underwent phacoemulsification cataract extraction combined with intraocular lens implantation. There are three ways to expand the pupil: ① 19 patients underwent mechanical debridement combined with radial pupil loosening; ② 11 eyes directly stretch the expansion of the pupil; ③ 13 separate adhesions alone, with the viscoelastic dilatation of the pupil. Results All pupils remained 3 ~ 3 5mm round, with no adhesions, with a certain degree of activity. Postoperative visual acuity: One week after surgery, 0 0 5 accounted for 62.8%, and one month after operation ≥ 0 5 accounted for 69 9%. Complications included 2 eyes (47%) with posterior capsular rupture, 6 eyes (13.9%) with corneal edema, 3 ~ 5 days edema and 1 iris ciliary body inflammation (23%). Conclusion Phacoemulsification for the treatment of small pupil uveitis complicated with cataract is safe and effective, can obtain good postoperative visual acuity, and pupil circle, is the ideal intraocular tissue injury minimal surgery
