To investigate the phacoemulsification treatment after vitrectomy combined with silicone oil tamponade. METHODS:Totally 102 cases (102 eyes) of cataract after vitrectomy combined with silicone oil tamponade during 2007-11/2011-11 were retrospectively analysed, 3 to 9 (mean 6.1) months after the vitreous surgery. Vitreous cavity infusion was used. The patients were first treated with phacoemulsification, anterior chamber injection of viscoat and silicone oil replacement, and then with intraocular lens implantation and circular posterior capsulotomy.Intraoperative and postoperative complications, postoperative vision and so on were observed. RESULTS:Four weeks after operation, visual acuity had varying degrees of improvement in 97 eyes and no improvement in 5 eyes among the 102 eyes of 102 cases; posterior capsular rupture occurred in 2 cases, no lens nucleus falling into vitreous body or choroidal detachment occurred. CONCLUSION: Phacoemulsification,silicone oil removal, intraocular lens implantation and circular posterior capsulotomy for complicated cataract after vitrectomy combined with silicone oil tamponade can effectively reduce intraoperative and postoperative complications, and meanwhile avoid the risks arising from the secondary operation.
