ABSTRACT:
A laser beam pattern modulator includes a light-transmissive, light-refractive element for rotating and/or linearly displacing the beam such that the refracted beam remains parallel to the incident beam and has the capacity: (a) to minimize a substantial quantity of irregularities in the treatment pattern from hot spots and cold spots in the laser beam; (b) to enlarge and blend the edges of the treatment patterns formed by the beam; and (c) to form an enlarged, multi-zone, aspheric, myopic, hyperopic or astigmatic treatment patterns. A method for treating corneal tissue with laser light, particularly excimer laser light, includes directing a beam of excimer laser light such as a broad beam with variable spot size through a beam modulator such as an anglable, rotatable quartz flat.
