ROCHESTER, N.Y., Feb. 27 -- Bausch & Lomb announced that the US Food and Drug Administration has approved the Bausch & Lomb Technolas 217A Excimer Laser System for use in the correction of hyperopia (farsightedness). With this additional approval, Bausch & Lomb said, the system now offers surgeons a full-treatment range from myopia (nearsightedness) up to -12.00 diopters, with or without astigmatism, to hyperopia up to +4.00 diopters, with or without astigmatism, which would make LASIK surgery available to more patients.
