At the ISRS 2009 Annual Meeting, Refractive Surgery Subspecialty Day, Rupal Shah, MD, reported six-month results evaluating the use of all-in-one femtosecond laser to treat myopia and myopic astigmatism without using an excimer laser.
The prospective clinical study included 250 eyes with myopia or myopic astigmatism, up to -10 D spherical equivalent, who were treated using a femtosecond laser to carve out a lenticule intrastromally. The lenticule is then extracted from the stroma after lifting a flap or through a small incision.
At six months, 97 percent of eyes were within 0.5 D of attempted correction, and 87 percent of eyes had a BCVA that was unchanged from, or better than, preop BCVA, while 83 percent had UCVA equivalent to preop BCVA. Refractions were stable, with a mean change of -0.16 between one week and six months postoperatively.
