Longterm results after phacovitrectomy and foldable intraocular lens implantation

Purpose: This study aimed to evaluate the longterm results of phacovitrectomy and foldable intraocular lens (IOL) implantation in eyes with significant cataract and co‐existing vitreoretinal diseases. Methods: We carried out a retrospective study of 186 eyes of 149 patients with various vitreoretinal abnormalities and visually significant cataracts. Vitreoretinal surgery was combined with phacoemulsification and foldable IOL implantation. Main outcome measures were visual acuity (VA), preoperative data, and intraoperative and postoperative complications. Results: The most common indications for surgery were non‐diabetic vitreous haemorrhage and proliferative diabetic retinopathy. Preoperative vision ranged from 0.6 to light perception; postoperative vision ranged from 1.2 to no light perception. Postoperatively, in 162 eyes (87.1%) VA improved by ≥ 3 lines on the decimal chart. In 14 eyes (7.5%), vision remained within 3 lines of preoperative levels and in 10 eyes (5.3%), vision had decreased by the last follow‐up. Postoperative complications included elevated intraocular pressure and posterior capsule opacification, corneal edema, macular edema, fibrinous reaction, vitreous hemorrhage, corneal epithelial defects, anterior chamber hyphema, choroidal detachment, persistent macular hole, posterior synechiae, recurrent retinal detachment, rubeosis iridis, neovascular glaucoma. Conclusions: Combined vitreoretinal surgery and phacoemulsification with foldable IOL implantation is safe and effective in treating vitreoretinal abnormalities co‐existing with cataract. Based on extensive experience with the combined procedure, we suggest that combined surgery is recommended in selected patients with simultaneous vitreoretinal pathological changes and cataract.

Combined clear corneal phacoemulsification, vitreoretinal surgery, and intraocular lens implantation.

PURPOSE: To evaluate the technical feasibility, outcome, and incidence of complications after combined clear corneal phacoemulsification with intraocular lens (IOL) implantation and vitreoretinal surgery. SETTING: Department of Ophthalmology, Giessen, Germany. METHODS: The results of combined cataract and vitreoretinal surgery in 38 eyes (36 patients) were retrospectively analyzed. All patients had clinically significant lens opacities and vitreoretinal pathology requiring pars plana vitrectomy. Thirty-seven IOLs were implanted in the capsular bag, and 1 was sulcus fixated. RESULTS: Postoperatively, visual acuity improved in 20 eyes (52.6%), was unchanged in 16 (42.1%), and was worse in 2 (5.3%). Postoperative complications consisted of anterior chamber fibrin exudation (3 eyes), hyphema (2 eyes), vitreous hemorrhage (1 eye), posterior capsule opacification (16 eyes), neovascular glaucoma (2 eyes), proliferative vitreoretinopathy and redetachment (1 eye), and retinal redetachment after silicone oil removal (1 eye). CONCLUSION: Compared with 2 separate operations in patients with significant lens opacities and vitreoretinal pathology, combined cataract and vitreoretinal surgery provided more rapid visual rehabilitation. The visual outcome and complications depended primarily on underlying posterior segment pathology and were not related to the combined procedure technique.     

Anterior segment complications after phacoemu-lsification combined vitrectomy and foldable intraocular lens implantation

AIM: To evaluate the anterior segment complications of phacovitrectomy and foldable intraocular lens (IOL) implantation in eyes with significant cataract and co-existing vitreoretinal diseases. METHODS: This retrospective study was consisted of 285 eyes of 238 patients with various vitreoretinal abnormalities and visually significant cataracts. Vitreoretinal surgery was combined with phacoemulsification and foldable IOL implantation. Main outcome measures were visual acuity, the preoperative data, and the anterior segment complications at postoperative 6 to 72 months. RESULTS: The most common indications for surgery were non-diabetic vitreous hemorrhage, proliferative diabetic retinopathy. Preoperative vision ranged from 20/30 to light perception and postoperative vision ranged from 20/20 to no light perception. Postoperatively, in 245 eyes (85.9%), visual acuity improved by 3 lines or more on the Snellen chart. In 24 eyes (8.4%), vision remained within 3 lines of preoperative levels and in 16 eyes (5.6%), vision had decreased at the last follow-up. The most common anterior segment pathological change was PCO in 50 eyes (17.5%), the second was corneal edema in 32 eyes (11.2%) and the third was elevated IOP in 31 eyes (10.8%). CONCLUSION: The combined vitreoretinal surgery and phacoemulsification with foldable IOL implantation is safe and effective.

PURPOSE: To evaluate the effectiveness, technical feasibility and incidence of complications after combining pars plana vitrectomy, phacoemulsification and intraocular lens implantation. MATERIAL AND METHODS: The results of combined vitreoretinal and cataract surgery in 100 eyes of 96 patients were retrospectively and prospectively analyzed. The mean follow-up period was 8.4 months.

Indications for vitreoretinal surgery included: persistent vitreous haemorrhage (28 eyes), vitreous hemorrhage combined with tractional retinal detachment (50 eyes), tractional retinal detachment without vitreous haemorrhage caused by proliferative diabetic retinopathy (7 eyes), rheumatogenous retinal detachment with proliferative vitreoretinopathy (10 eyes) and dislocated crystalline lens in the vitreous (5 eyes). RESULTS: Postoperatively, best corrected visual acuity improved in 81 eyes (81%)- by two lines or more in 31 eyes (31%) - by less than two lines in 50 eyes (50%). In 14 eyes (14%) visual acuity was unchanged and was worse in 5 cases (5%). Postoperative complications included fibrin reaction, posterior synechias of the iris, vitreous hemorrhage, neovascular glaucoma, posterior capsule opacification, redetachment of retina. CONCLUSIONS: Our cases confirm previous study, that performing phacoemulsification, IOL implantation and vitrectomy in one operation is safe and allows visual recovery with good technical results.

Combined pars plana vitrectomy and cataract surgery: outcome of phacoemulsification versus manual extracapsular cataract extraction through a sclerocorneal tunnel.

BACKGROUND AND OBJECTIVE: To compare the results of combined pars plana vitrectomy and cataract extraction with intraocular lens implantation by phacoemulsification versus manual extracapsular cataract extraction through a sclerocorneal tunnel. PATIENTS AND METHODS: Retrospective chart review of all patients who underwent combined pars plana vitrectomy with intraocular lens implantation and phacoemulsification or extracapsular cataract extraction through a sclerocorneal tunnel between March 1992 and July 2002. RESULTS: Fifty-four eyes of 51 patients were evaluated. Mean age was 69.68 +/- 9.11 years, and mean follow-up was 9 months. Phacoemulsification was performed in 35 cases (64%) and manual extraction in 19 cases (36%). Visual acuity improved from mean logarithm of the minimal angle of resolution 1.69 +/- 0.54 before surgery to 1.22 +/- 0.76 after surgery. There was a greater improvement of visual acuity in the phacoemulsification group (0.59 +/- 0.67) than in the extracapsular cataract extraction group (0.22 +/- 0.68) (P = .06). Final visual acuity was correlated to the vitreoretinal pathology. Ultrasound biomicroscopy showed well-positioned foldable or rigid intraocular lens in the bag or in the sulcus. CONCLUSION: Combined cataract extraction by phacoemulsification or extracapsular cataract extraction through sclerocorneal tunnel and pars plana vitrectomy are safe and effective procedures.
