AIM: To investigate the therapeutic effect of phacoemulsification with intraocular lens on uveitis complicated cataract. METHODS:Totally 32 cases (38 eyes) of uveitis complicated cataract were performed with phacoemusification,through separating adhesion with viscoelastic agents needle. You should make circular cut off along the pupillary margin with intracapsular shear if the pupil cannot expand. RESULTS:Visual acuity of 33 eyes(87%) were improved.The postoperative visual acuity was＞0.5 in 22 eyes,0.3-0.5 in 6 eyes,0.1-0.25 in 7 eyes, ＜0.1 in 3 eyes. There were no serious complications and no aggravation of old uveitis. Postoperative pupill was near circle. Some pupils recovered light response. No serious complication presented. CONCLUSION:Excision of the pupillary margin in phacoemulsification with small pupil is safe and effective. The related complications can be decreased by skillful manipulation.
