Purposes: To evaluate the effect of phacoemulsification in the patients with uveitis,secondary glaucoma and complicated cataract.Methods: Phacoemulsification and implantation of a foldable intraocular len wasperformed in 12 patients(13 eyes) with uveitis, secondary glaucoma and complicatedcataract. The complications, intraocular pressures (IOP), and visual acuity wereobserved postoperatively.Results: No severe complication was found in the patients postoperatively or within theoperation procedure. The visual acuity was improved after the operation ( P < 0. 05) .The intraocular pressures and/or the number of antiglaucoma medications reduced in 3months of the follow-up time.Conclusion: phacoemulsification is the best way to treat the patients with secondaryglaucoma and complicated cataract caused by uveitis.
