A Prospective Randomized Comparison of Fellow Eyes Undergoing LASIK or PRK With a Wavefront-guided Excimer Laser Versus a Wavefront-optimized Excimer Laser
Subjects with myopia, hyperopia and astigmatism are being randomized to be treated in one eye
with a wavefront-guided excimer laser and their fellow eye treated with a wavefront-optimized
excimer laser.
with a wavefront-guided excimer laser and their fellow eye treated with a wavefront-optimized
excimer laser.
Subjects with myopia, hyperopia and astigmatism are being randomized by ocular dominance to
be treated with either PRK or LASIK. One eye will be treated with a wavefront-guided excimer
laser and the fellow eye will be treated with a wavefront optimized excimer laser.
