Postvitrectomy keratopathy.
Twenty-six of 75 eyes undergoing pars plana vitrectomy developed significant corneal complications requiring treatment. Slow or nonhealing epithelial abrasions, recurrent corneal erosion, and microcystoid and striate keratitis were among the most frequent problems. Significant predisposing factors included diabetes, surgical trauma such as epithelial debridement and prolonged operative time, aphakia, and postoperative glaucoma or hyphema. Corneal complications may be minimized with careful preoperative and operative precautions.
