Objective. Research objective is to assess the excimer laser photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) in ametropia correction in patients with pseudophakia.  Methods. It was conducted the analysis of refractive surgery after lens extraction and intraocular lens implantation in 38 patients 20–81 years with secondary ametropia on pseudophakic eyes: PRK performed on 10, LASIK – 44 eyes. Analysis of visual acuity and corneal parameters was carried out after 1, 2 and 3 months after surgery. Results. By the end of the observation period in patients after PRK and LASIK has stabilized performance in visual acuity without correction and with correction. Stable refractive effect was observed after LASIK arrived after a month, and after PRK after 2 months. Conclusions. The use of excimer laser technology in the secondary ametropia after lens extraction with intraocular lens implantation is safe and fairly predictable method for correcting visual acuity.
