Approval Order Statement 
Approval for the nidek ec-5000 excimer laser system for photorefractive keratectomy for moderate myopia with astigmatism. This device is intended for use in: 1) the reduction or elimination of myopia with astigmatism raning in severity from -1. 00 to -8. 00 diopters (d), in terms of manifest refraction spherical equivalent (mrse), with refractive astigmatism ranging in severity from -0. 5 to -4. 00 d cylinder by manifest refraction; due to cylinder coupling effects on sphere, the lower range of the intended use must be restricted in a step-wise fashion. A nomogram lookup table is provided for specific treatment combinations. 2) patients who have a stable history of both pretreatment myopic astigmatism (i. E. , magnitude of change in manifest refraction of <0. 5d per year in terms of mrse for at least one year proceeding treatment) and pretreatment astigmatism (i. E. , a magnitude of change of <0. 5d per year in cylinder for at least one year preceding treatment); and 3) patients who are over 21 years of age.
