method for laser correction of cornea shape

摘要

A method for laser correction of cornea shape comprises the moving of excimer laser beam with Gaussian radial distribution of energy density in transverse section. On the basis of ceratotopogram analysis a type of cornea surface steepness in the area for correction is determined. The moving of laser light-spot is carried out along spiral or circular trajectory, with a center in the highest point of area intended for correction.
