—Removal of cataracts that significantly impair vision and subsequent implantation of intraocular lenses are sometimes performed in diabetic patients who may need future vitreoretinal surgery. Even with uneventful cataract surgery and posterior chamber intraocular lens implantation, the progression of diabetic retinopathy and the development of anterior segment neovascularization have been reported.¹ Such diabetes-related problems frequently necessitate vitreoretinal surgery in the pseudophakic eye, including laser photocoagulation and pars plana vitrectomy. Based on theoretical concepts and clinical experience, we recommend that surgeons planning cataract surgery in patients with significant diabetic retinopathy consider using posterior chamber intraocular lenses with an optic diameter of 7 mm, no positioning holes, and a planoconvex configuration.

A 7-mm intraocular lens provides 36% more optic area than a 6-mm lens. Assuming adequate pupillary dilatation, this increased area provides the vitreoretinal specialist an easier view of the retinal periphery and better stereopsis than a smaller . . . [Full Text PDF of this Article]
