Central Toxic Keratopathy
Central toxic keratopathy (CTK) describes a rare, acute, non-inflammatory complication most associated with excimer laser ablation surgery (e.g., laser assisted in situ keratomileusis (LASIK) or photorefractive keratopathy (PTK) surgery). However, idiopathic cases have been reported and an association with contact lens use has been made. Potential cases have been associated with selective laser trabeculoplasty and topical anesthetic use as well. Fraenkel and colleagues first described CTK in 1989 as being inflammatory in nature but the condition has subsequently been recognized as a non-inflammatory process.
