简要总结
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.
详细描述
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.
