[The possibilities for optimizing the surgical prevention of the progression of myopia]. / Vozmozhnosti optimizatsii khirurgicheskoi profilaktiki progressirovaniia blizorukosti.

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.

[Scleral fortification in children at high risk of progressive myopia]. / Ukreplenie sklery u detei s povyshennym riskom progressirovaniia blizorukosti.

To improve scleroplasty efficacy in children at a high risk of postoperative progress of myopia the authors have developed a new surgical method involving increase of the transplant size and its preoperative treatment with a foamy composition intended for filling the body cavities. Experimental biomechanical and morphologic studies have demonstrated that such treatment improves the transplant elasticity and strength, provides its better adhesion and fixation to the sclera at the expense of excellent adhesive properties of the foamy composition, and intensifies revascularization and stabilization processes in the connective tissue. Such surgery was effectively performed in 46 patients.

[Mathematical analysis of the causes of unsatisfactory results of scleroplasty in progressive myopia]. / Matematicheskii analiz prichin neudovletvoritel'nykh rezul'tatov skleroplastiki pri progressiruiushchei blizorukosti.

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.

[An analysis of the late results of scleroplasty in progressive myopia]. / Analiz otdalennykh rezul'tatov skleroplastiki pri progressiruiushchei blizorukosti.

Analysis of remote (to 9 years) results after 256 sclera-enhancing operations in patients with progressive myopia, aged from 7 to 48 years, revealed stabilization of the process in 72% of patients, the dependence of the effect on the form of myopia and the patient's age. As to prognosis, early acquired myopia and the children age are less favourable. The number of surgical failures increases in remote terms; in some patients the effect can be transitory. Therefore, surgical results should be judged about minimum 3 years after operation. Comparative examination of the state of a complex "graft-sclera" by means of computer tomography in satisfactory and unsatisfactory surgical results has shown that myopia continues to progress, as a rule, in case of reduced scleral density and the absence of roentgenologic signs of the graft. The action of scleroplasty on the appearance and course of central chorioretinal dystrophies has been studied.
