Progressive myopia is a pressing problem of ophthalmology. Scleroplastic surgery is a pathogenetically validated method for treating this condition. The authors propose a new method for allotissue preservation, ensuring preservation of biological characteristics of tissues for any period without restriction, so that the material for transplantation were constantly available. A new shape of the graft is proposed: with a duplicature pouch and lateral incisions on one end, like a fur-tree. Such a design ensures a reliable position of the graft on scleral surface with an accent on the posterior pole and prevents pushing out of the graft from Tenon's space, which often occurs with common grafts. Transplants of a new shape were used in 2050 patients; the operation is easy to perform and its results are highly effective.

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.
