or older with -0.25 to -13.0 D of myopia whose refractive change for one year prior to
treatment is within =0.25 D for low myopia (5 -7.0 D MRSE) or within ± 0.25D for high
myopia (> -7.0 D MRSE).
The clinical indication was expanded in Supplement 1to
include PRK treatment of myopic astigmatism (-1.00 to -8.00 D MRSE with -0.5 Io -4.00
D cylinder). Supplement 6 (approved September 4, 2001) flirther expanded the clinical
indication to include laser assisted in-situ keratomilicusis (LASIK) for the treatment of
myopic astigmatism (-0.25 to -14.00 D MRSE with up to -6.00 D astigmatism) using an
