Mathematical statistics-based analysis of the results of 256 surgeries, carried out in 219 patients with high progressive myopia, has revealed a number of factors significant for effective outcomes and failures of the operations. Among prognostically favorable factors are the school and congenital forms of myopia, young or adult age of the patients, a moderate progress of myopia (up to 1 diopter yearly), a noninherited pattern of myopia or a dominant type of inheritance, absence of somatic diseases. The factors that predict a possible unfavorable outcome are early acquired myopia, patients' childhood age, high rate of myopia progress, the recessive type of inheritance, concomitant diseases. The contribution of every factor to the result has been determined. The analysis has helped single out the group of patients at risk of an unfavorable result of surgery.
