Laser Keratoplasty: Refractive and Functional Results in Hypermetropic and Mixed Astigmatism Correction
The aim of the study is to determine the effectiveness of correction of a simple hypermetropic and mixed astigmatism by means of a laser thermokeratoplasty according to the technology developed on “OKO-1” device.
Materials and methods. There have been analyzed the results of treatment of 98 patients (169 eyes) with a simple (58 eyes) astigmatism and the patients with mixed astigmatism (111 eyes).
Results. A year after the operation there has been obtained the evidence of effectiveness of the technique suggested: a mean cylindrical refraction component has been reduced from –2,90±0,71 to –0,74±0,67 diopter (р<0,05), and a mean spherical component — from 1,79±0,83 to 1,08±0,11 diopter (р<0,05). Due to the increase of cornea refraction, visual activity has increased both in cases without correction and in those with glasses correction. And vision without correction after a laser thermokeratoplasty (0,64±0,07) has exceeded a mean visual activity before the operation (0,51±0,02) (p<0,05).
