Abstract
BACKGROUND AND OBJECTIVE: To evaluate the effectiveness and safety of combining phacoemulsification (PEA), pars plana vitrectomy (PPV), and intraocular lens (IOL) implantation. PATIENTS AND 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.
