Surgical results of pars plana vitrectomy combined with SICS: To evaluate the technical feasibility, safety, outcome, and incidence of complications after combined clear corneal small incision cataract surgery (SICS) with intraocular lens (IOL) implantation and vitreoretinal surgery. METHODS: Combined operations of SICS and PPV were performed on 52 eyes of 52 patients with cataract and vitreo retinal diseases. RESULTS: 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: 6/12 or better (9 eyes), 6/24 to 6/60 (24 eyes), 3/60 (5 eyes), 1/60 (10 eyes), and fingers counting (FC) to light perception (LP) (4 eyes). In 38 eyes BCVA was 6/36 or better, and in 9 eyes it was 6/12 or better postoperatively. Postoperative complications included posterior capsular opacification (7 eyes); secondary glaucoma (1 eye); and retinal detachment (2 eyes). INTRODUCTION: Cataract is frequently associated with vitreoretinal pathology such as Vitreous hemorrhage, retinal detachment, proliferative vitreoretinal disease, especially in patients with diabetes mellitus, ocular trauma and elderly population. The cataract can be removed together with vitrectomy or later on in a separate surgical procedure. The primary indication for the primary removal of cataract and vitrectomy is significant lens opacification that diminishes visualization of the posterior segment and hinders the operations. The methods for removal of cataracts include lensectomy, extracapsular Cataract extraction, and small incision cataract surgery. Lensectomy is the removal of the cataract during a vitrectomy procedure. It is performed either with a vitrectomy probe, or a vectis. The lens is usually removed completely, with its anterior and posterior capsule. Extracapsular cataract extraction is performed through an 8-mm corneal, or corneoscleral, incision. The anterior lens capsule is removed, and the nucleus is mechanically expressed through the incision. Intraocular lens is implanted in the capsular bag. The incision must be sutured at the end of the procedure. Small incision cataract surgery is performed through a 6mm corneal incision. The nucleus of the lens is extracted with lens vectis. A foldable intraocular lens is implanted in the capsular bag. The incision requires no suturing at the end of the procedure. Small incision cataract surgery has many advantages over lensectomy and extracapsular cataract extraction. Smaller incision induces less astigmatism, makes the globe more stable, and decreases the possibility of a wound leak. Postoperative rehabilitation is also faster (Scharwey et al., 1999). In the current study, we retrospectively analyzed a consecutive series of 52 eyes in which vitreoretinal surgery was combined with clear corneal small incision cataract surgery .
