The study discusses the refractive operations performed by means of classical surgery. Presented are briefly the keratophakia, epikeratophakia and keratomileusis; largely presented are: radial keratotomy, transversal keratotomy and Ruiz' operation. The two last methods are used for correction of astigmatism. The presented problems are illustrated by personal material.
