Surgery for post-vitrectomy cataract

Abstract

Background Cataract formation or acceleration can occur after intraocular surgery, especially following vitrectomy, a surgical technique for removing the vitreous which is used in the treatment of disorders that affect the posterior segment of the eye. The underlying problem that led to vitrectomy may limit the benefit from cataract surgery. Objectives The objective of this review was to evaluate the effectiveness and safety of surgery for post-vitrectomy cataract with respect to visual acuity, quality of life, and other outcomes. Search methods We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (

Biochemical analysis of the living human vitreous

“…Despite a seemingly exponential increase in the number of vitrectomies being performed annually, there has been a stark deficiency of research undertaken to determine whether all perioperative parameters are being optimized to enhance the visual outcomes for each patient. On the other hand, it is concerning that the formation or progression of nuclear sclerotic cataract has become an expected outcome following a vitrectomy, especially since these cataracts often lead patients to experience visual impairment significant enough to necessitate subsequent cataract surgery . Until now, one of the basic scientific principles of a vitrectomy appears to have been overlooked: The solution being removed from the eye is fundamentally different from the solution which is used as a replacement.…”

Comparative study of femtosecond laser‐assisted cataract surgery and conventional phacoemulsification in vitrectomized eyes

“…Cataract development is the most commonly recognized sequelae of vitreoretinal surgery with reported incidence after pars plana vitrectomy varying between 12.5% and 80% . The exact aetiology behind this phenomena is not known, with several different theories being postulated .…”
