Abstract
Changes in the values of optical power of cornea in patients after photorefractive keratectomy (PRK) obtained by Fourier analysis of videotopographic picture of cornea were investigated. The authors compared changes of cornea surface (optical power) in patients with preoperation myopia up to 6 and more than 6 diopters.
Moreover, the changes of absolute values of corneal optical power were compared with the development of refraction of the optical system as a whole.
