OBJECTIVE To evaluate the effectiveness and safety of combining phacoemulsification (PEA), pars plana vitrectomy (PPV), and intraocular lens (IOL) implantation. METHODS Combined operations of PEA and PPV were performed in 76 eyes of 54 patients with cataract complicated by proliferative diabetic retinopathy (PDR). The mean follow-up period was 24.4 months. Gas tamponade was employed in 15 eyes. IOLs were implanted during surgery. RESULTS Visual acuity improved by 2 lines or more in 59 eyes (78%). Forty-seven eyes (77%) without tamponade and 12 eyes (80%) with tamponade had improved visual acuity. Postoperative complications included fibrin reaction in 8 eyes (10%), posterior synechia of the iris in 11 eyes (14%), and recurrence of retinal detachment in 8 eyes (10%). The incidence of these complications and of additional operations was higher in eyes that required tamponade, which corresponded with the severity of each case and the complexity of the surgical procedures. CONCLUSIONS Although further studies are indicated, this study suggests that the combined operation of PPV, PEA, and IOL implantation is safe and effective for patients with PDR. The choice of IOL may be correlated with postoperative complications.

D012163	Retinal Detachment	Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery.

D002386	Cataract	Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence).
