Surgical burs designed for abrasion of the cornea. They typically consist of a shank of steel or other hard metal with a well-differentiated diamond sphere at its working tip, a proximal end to fit into the rotary device, and a neck that connects the shank to the working part. Corneal abrasion burs are used to polish corneal scratches and/or the pterygium bed after surgical removal and/or abrasion of lid margin lesions. These burs are intended for use with a special slow-rotation electrically powered ophthalmic device (e.g., an ophthalmic electric spud).
