Combined phacoemulsification, intraocular lens implantation, and vitrectomy for eyes with coexisting cataract and vitreoretinal pathology.

Anna-Maria Demetriades, John Gottsch, Robert H. Thomsen … (2003)

To report the preoperative, intraoperative, and postoperative outcomes of combining phacoemulsification and posterior chamber intraocular lens (IOL) implantation with pars plana vitrectomy in eyes with significant cataract and coexisting vitreoretinal pathology. Retrospective, consecutive, interventional case series. Charts of patients undergoing combined procedures at the Wilmer Ophthalmologic Institute between March 1995 and May 2000 were reviewed. In all, 122 eyes of 111 patients were identified. Patient ages ranged from 27 to 89 years (mean 65). Forty-three eyes had diabetic retinopathy; 11 had undergone vitrectomy previously. Macular pathology (hole, membrane, choridal neovascularization) was present in 69 eyes. The most common indications for surgery were diabetic vitreous hemorrhage, macular hole, epiretinal membrane, and retinal detachment. In all cases, phacoemulsification and IOL implantation were performed before vitreoretinal surgery. Preoperative vision ranged from 20/30 to light perception and postoperative vision ranged from 20/20 to no light perception. In 105 patients vision improved, in 7 there was no change, and in 10 vision decreased. Postoperative complications included opacification of the posterior capsule, increased intraocular pressure, corneal epithelial defects, vitreous hemorrhage, retinal detachment and iris capture by the IOL. Combined surgery is a reasonable alternative in selected patients. Techniques that may simplify surgery and reduce complications include: careful, limited, curvilinear capsulorhexis; in-the-bag placement of IOLs; use of IOLs with larger optics; suturing of cataract wounds before vitrectomy; use of miotics and avoidance of long-acting dilating drops in patients with intravitreal gas; and use of wide-field viewing systems.

Combining phacoemulsification with pars plana vitrectomy in patients with proliferative diabetic retinopathy: a series of 223 cases.

Lauren J. Lahey, Brian Kearney, Elizabeth Francis (2003)

To describe the results of combined phacoemulsification, insertion of posterior chamber intraocular lens (PCIOL), and pars plana vitrectomy for patients with retinal disorders resulting from diabetic retinopathy. Retrospective, consecutive, noncomparative, interventional case series. Two hundred twenty-three patients with vitreoretinal disorders secondary to diabetic retinopathy. A case series of 223 consecutive patients with retinal disorders resulting from diabetic retinopathy who underwent combined phacoemulsification, insertion of PCIOL, and pars plana vitrectomy. Vision, number of secondary procedures, and complications. Two hundred twenty-three patients (153 with vitreous hemorrhage, 58 with traction retinal detachment, and 12 with macular traction) underwent combined surgery. The average increase in vision was 4.3 Snellen lines. The average follow-up was 10 months. Retinal detachment occurred in 5% of patients who underwent surgery. Diabetic macular edema was found in 12% after combined surgery. Cystoid macular edema was found in 3%. Vitreous hemorrhage requiring another procedure occurred in 11%. Twenty-two patients (10%) required a repeat vitrectomy (12 for vitreous hemorrhage and 10 for retinal detachment). Combined phacoemulsification, insertion of PCIOL, posterior capsulectomy, and pars plana vitrectomy can be used to treat patients with complications resulting from proliferative diabetic retinopathy. Combined surgery may prevent a second operation for postvitrectomy cataract, allowing earlier visual rehabilitation.
