ALGERBRUSH II is used by ophthalmologists, ER physicians, and optometrists who are trained and licensed to remove foreign bodies and rust rings from the eye of a patient. The Algerbrush rotary instrument uses a very low torque motor powered by a single AA battery to "brush" rather than drill the rust ring leaving a smooth surface on the cornea or sclera. This promotes healing much faster than with other instruments.

Carbide burrs (for corneal rust ring removal) are available in 1mm or .5mm diameter (the .5mm is by far the most common for the AlgerBrush).
