Corneal and conjunctival changes after posterior segment surgery.

Significant corneal compromise can occur subsequent to vitreoretinal surgery, especially in diabetic corneas. Associated factors include the operating lens systems used, irrigating solutions, preoperative lens and anterior capsule status, and the use of adjunctive agents such as intraocular gasses or silicone oil. Corneal, conjunctival, and ocular surface complications can also occur after scleral buckling procedures, often related to buckle extrusion or infection.
