Band keratopathy is characterized by the appearance of an opaque white band of variable density across the central cornea, formed by the precipitation of calcium salts on the corneal surface (directly under the epithelium).
This form of corneal degeneration can result from a variety of causes, either systemic or local, with visual acuity decreasing in proportion to the intensity of the deposition (see the image below). (See Etiology.)

Superficial debridement generally restores vision and comfort for most patients with band keratopathy, although failure to manage the source of the condition often leads to recurrence. (See Prognosis, Treatment, and Medication.)
