This tool has a very low torque motor powered by a single AA battery (included). The tip (burr) in this rotary instrument is used as a “brush” rather than a drill and the rust ring is thus “brushed” from the cornea or sclera leaving a smooth surface which in turn heals much faster compared to other instruments which may be used for this purpose. The tip and chuck are made from stainless steel and can be autoclaved. Do not autoclave the handle!
You can purchase replacement tips (burrs) for the Algerbrush from Gulden.
