Abstract
An epithelial removal tool and epithelial surgical procedure emits light from a lower end of the removal tool to provide a fixation light, a point for the patient to focus on to prevent eye movement and avoid injury during ophthalmic surgery. The removal tool has a housing which secures one or more removal members in fixed position. The removal members are preferably provided by synthetic brush bristles. One or more optical fibers extend from an upper portion of the housing, through the brush bristles, and to the light region which provides a fixation point that is centrally located on the terminal end of the bristles and on the bottom of the removal tool. In some embodiments, rather than a brush the removal tool may be in solid form, preferably provided by a pliant member formed of a polymeric material which transmits sufficient light to provide a fixation point.
