[The classification, causes and clinical manifestations of the complications from specialized laser keratomileusis in the correction of myopia and hypermetropia].

Complications of specialized laser keratomileusis (LASIK) are analyzed in 1667 patients with 1.0-19.5 diopter myopia and hypermetropia of +2.25-10.0 diopters. LASIK was carried out by the standard method using Hansatome TM 230 HT device and eximer laser Nidek EC-5000. Classification of LASIK complications depending on the mechanism of exposure and stage at which they manifest is offered. Such complications as inadequate adaptation of the corneal flap (0.7%), lensodonesis (0.1%), viral keratitis (0.05%), turned-under edge of a flap (0.4%), stromal "feedback" pouch are described for the first time. Causes of complications are enumerated and analyzed and methods for their correction are described. The authors claim that the type and incidence of LASIK complications are largely determined by the experience of the surgeon and quality of equipment. Use of new lasers and new keratomes will rule out many complications.
