Summary
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.
Clinical Details
Official title: Comparison of Scheimpflug Photos of the Crystalline Lens in Patients Who Have Undergone Vitrectony Surgery and Controls

photographs will be taken for evaluation of level and progression of cataract development.
