title: Endothelial cell counts following pars plana vitrectomy in pseudophakic and aphakic eyes.
abstract: In 13 pseudophakic eyes, endothelial cell counts remained stable following pars plana vitrectomy. The posterior chamber pseudophakos apparently had a protective effect on the corneal endothelium, even though the posterior lens capsule was removed during surgery. By contrast, in nine aphakic eyes, a statistically significant (p greater than .05) cell loss of 7.6% occurred after pars plana vitrectomy. We conclude that vitrectomy therefore poses an increased risk to the cornea in aphakic, but not in pseudophakic eyes.
