A technique to correct ametropia with phakic intraocular lenses (PIOL) was developed on the basis of the analysis of anatomic, clinical, and functional condition of 409 eyes of 274 patients with various types of refraction, and operations performed on 279 eyes with myopia or hyperopia followed tip for 2 to 10 years. Its algorithm is a step-by-step system including: patient selection based on a comprehensive clinical and functional examination with an obligatory ultrasound biomicroscopy and psychological testing; choice of PIOL design taking into account initial anatomic and functional parameters of the eye; simulation of the surgical effect using contact lenses allowing for calculation of the optimal PIOL power; choice of an adequate anesthesia method; direct PIOL implantation technique, which, when necessary, is combined with a simultaneous correction of astigmatism and strabismus; pre- and post-operation pleoptic treatment in cases of amblyopia of various degrees.
