This technology has been available for about three decades and was originally used by IBM to etch computer chips. In the early eighties this technology was applied to reshaping corneas and the FDA trials began. After having completed animal studies and the treatment of blind human eyes in the mid-eighties, the FDA allowed corneal surgeons to treat the first human sighted eyes in 1987. At a recent International Refractive Surgery meeting the investigator who performed the first excimer laser treatment on a person with healthy, normal eyes in the United States presented follow-up data. At this time the person is still 20/20 and is absolutely thrilled with her visual results.
