AIM:To explore the effective surgical treatment of iritis complicated with cataract pupil adhesion.METHODS:Totally 21 cases(27 eyes) with iritis complicated with cataract and pupil adhesion were collected, all pupil diameter <4mm after tropicamide eye drops dilating the pupil. There were visual acuity of light perception to 0.2 and optical positioning uncertainty 1 case (1 eye), corneal old KP (+) 15 eyes, aqueous flare (-), pupil extensive posterior adhesions 3 eyes, occlusion of pupil 2 eyes and iris bombe high intraocular pressure 2 eyes. After separating the adhesions iris, tweezers tearing the pupil area or edge of the pupil machine membrane, fiber iris retractors dilated the pupils and conventional phacoemulsification were carried out. The postoperative reaction and visual acuity were observed.RESULTS:Visual acuity of postoperative 1 month, 25 eyes all improved compared with preoperation (93%), better than 0.5 in 16 eyes(59%), 0.3 to 0.5 in 5 eyes(19%), 0.1 to 0.3 in 3 eyes(11%), worse than 0.1 in 2 eyes, no change in 1 eye(complicated with optic nerve atrophy). Postoperative pupil was almost physiological round in 20 eyes (74%), irregular in 7 eyes (26%). There were 6 eyes (22%) pupil diameter> 7mm, 2 eyes(7%) of glare.CONCLUSION: Phacoemulsification combined with microscopic iris retractors dilating pupil can successfully completed iritis complicated with cataract pupil adhesion. Postoperative visual acuity and visual function significantly improve. It is an effective treatment. 
