摘　　要：BACKGROUND AND OBJECTIVE: To compare two kinds of cataract removal methods com bined with pars plana vitrectomy and posterior chamber intraocular lens (PC-IOL ) implantation. PATIENTS AND METHODS: Cataract removal was performed by either p hacoemulsification or extra-capsular cataract extraction (ECCE) and followed by pars plana vitrectomy and PC-IOL implantation. Between May 1996 and June 2001, 31 and 22 patients with cataract and vitreoretinal disease were treated by phac oemulsification and ECCE, respectively, combined with pars plana vitrectomy and PC-IOL implantation. Preoperative demographic data and postoperative vision, as tigmatism change, and complications were analyzed. RESULTS: The mean age of pati ents in the phacoemulsification and ECCE groups was 62.5 and 63.4 years, respect ively. Diabetes mellitus was the most common underlying disease resulting in vit reous opacity. Vision improved in 87.1%of the phacoemulsification group and 59. 1%of the ECCE group. The change in astigmatism after surgery was 0.92 ±1.08 D (P=.001) in the ECCE group and 0.25 ±0.74 D (P=.087) in the phacoemulsification group. There were fewer postoperative complications, including recurrent vitreo us hemorrhage, increased intraocular pressure, and iris changes in the phacoemul sification group than in the ECCE group. CONCLUSION: Phacoemulsification and ECC E combined with pars plana vitrectomy and PC-IOL implantation are both effectiv e surgical methods to achieve better and more rapid visual rehabilitation for pa tients with combined cataract and vitreoretinal disease. In this study, phacoemu lsification combined with pars plana vitrectomy and PC-IOL implantation resulte d in greater improvement in vision, less astigmatism change, and fewer postopera tive complications.BACKGROUND AND OBJECTIVE: To compare two kinds of cataract removal methods com bined with pars plana vitrectomy and posterior chamber intraocular lens (PC-IOL ) implantation.
