The article presents a clinical case of the intraocular lens power calculation and cataract phacoemulsification in a patient after anterior radial keratotomy. Features of conducting such patients are inadequate measurement accuracy of the corneal refractive power operated by standard keratometry, difficulties in measuring the axial length of the eye, absence of accurate formula for intraocular lens power calculation, the choice of surgical approach and the reduction of the endothelial cells density in the long term after the anterior radial keratotomy. Measurement of the refractive power of the cornea by means of modern scanning corneal topography, the axial length of the eye by non-contact laser interferometers, the application of the third generation formulas with amendment for the intraocular lens power calculation allowed us to avoid hyperopic refractive error in the postoperative period. Individual approach to the choice of surgical approach depends on the width of the «safety zone» between the edges of the tunnel and keratotomy scars. Considering scars convergence to the center of the cornea prevents scar dehiscence during cataract phacoemulsification. The use of endothelium protection measures allowed to minimize the cell loss.

Key words: anterior radial keratotomy, cataract, phacoemulsification.
