The AlgerBrush II is used by ophthalmologists, ER physicians and, optometrists who are trained and licensed to remove foreign bodies from the eye of a patient. Rust rings are normally caused by a ferrous foreign body accidentally striking the cornea or sclera of the patient. When the foreign body (usually a spark produced by a grinding wheel or welding torch) strikes the eye it will, when combined with the moisture in the eye, cause the development of rust rings. The AlgerBrush II is used for the expressed purpose of removing these rust rings from the eye. The AlgerBrush II has a very low torque motor powered by a single AA battery. The burr in this rotary instrument essentially “brushes” the rust ring from the cornea or sclera leaving a smooth surface which in turn heals much faster and cleaner than with other instruments which may be used for this purpose. The AlgerBrush II has been CE marked since 1998. In combination with the diamond burr option it is also used as an adjunct to pterygium procedures as well as by veterinarians for treatment of recurrent corneal ulcers.
