A retrospective study included 30 cataract cases (30 eyes) with history of vitrectomy. Phacoemulsifica-tion or small incision non-phacoemulsification was performed with vitreous irrigation of 23G TSV. Observe the visual acuities, intraoperative and postoperative complications. Posterior capsule rupture intraoperatively occurred in one patient with phacoemulsification. Three patients suffered intraocular hypotension postoperatively, including one with choroidal detachment, and the other two probably with leakage from incisions. However,the intraocular pressure rised to normal after treatment. Corneal edema and aqueous flare postoperatively occurred in four patients with hard nucleus cataract and three patients with diabetic retinopathy. There were no serious complications occurred in all patients, such as sclera collapse, nucleus sinking into vitreous chamber and bleeding in epichoroidal space. The visual acuities were improved after operation in twenty-eight patients.
