Comparison of Scheimpflug Photos of the Crystalline Lens in Patients Who Have Undergone Vitrectomy Surgery and Controls

Completed

Conditions studied: Nuclear Sclerotic Cataract

In brief

Progression of nuclear sclerotic cataract after pars plana vitrectomy has been recognized for many years The mechanism for the rapid progression of nuclear sclerotic cataract remains unclear. The objective of this trial is to evaluate and compare the level and progression of cataract advancement in controls versus eyes that have undergone 20-gauge pars plana vitrectomy and 25-gauge pars plana vitrectomy.
