To evaluate the technical feasibility, safety, outcome, and incidence of complications after combined clear corneal phacoemulsification (PEA) with intraocular lens (IOL) implantation and vitreoretinal surgery.
Combined operations of PEA and PPV were performed on 52 eyes of 52 patients with cataract and vitreoretinal diseases.
The mean follow-up time was (10.3+/-2.8) months. Postoperatively, visual acuity improved in 46 eyes (88.5%); was unchanged in 6 eyes (11.5%). The best-corrected visual acuities (BCVAs) were the following: 20/40 or better (9 eyes), 20/50 to 20/100 (24 eyes), 20/200 (5 eyes), 20/400 (10 eyes), and fingers counting (FC) to light perception (LP) (4 eyes). In 38 eyes BCVA was 20/200 or better, and in 9 eyes it was 20/40 or better postoperatively. Postoperative complications included posterior capsual opacification (7 eyes); secondary glaucoma (1 eye); and retinal detachment (2 eyes).
Although further studies are indicated, our study suggests that the combined operation of PPV, PEA and IOL implantation is safe and effective for patients. The visual outcome and complications depended primarily on underlying posterior segment pathology and were not related to the combined procedure technique.

    ABSTRACT: Objective: To determine the outcomes of early vitrectomy and endolaser photocoagulation effects during phacoemulsification in cataractous eyes with diabetic retinopathy. Study Design: Descriptive study. Place and Duration of Study: Ophthalmology Department Unit-II, DUHS, Civil Hospital, Karachi, and Al-Noor Eye Clinic, Karachi, from February 2009 to December 2010. Methodology: Consecutive 54 patients with 7-15 years duration of type II diabetes with severe non-proliferative diabetic retinopathy (NPDR) and early proliferative diabetic retinopathy (PDR) who had cataract grade I and II underwent vitrectomy, endolaser photocoagulation and phacoemulsification with IOL implantation. Best corrected visual acuity was main outcomes measure assessed till 6 months follow-up. Results: Out of 54 eyes, 32 patients were females and 22 were males. Majority 47 (87%) eyes gained significant (p < 0.001) improvement of best corrected visual acuity of four lines or better while 5 (9.3%) eyes retained stable visual acuity. In only 2 eyes, vision declined to 3/60 or less. Conclusion: Early vitrectomy with phacoemulsification in severe NPDR and early PDR patients, if assisted or augmented with endolaser photocoagulation, maximizes, early visual rehabilitation with less morbidity and may retard progression of retinopathy.
