Krasutskyi V. Optimisation of subepithelial photorefractive keratectomy of myopia at different degrees.

The thesis studied the results of an improved method for correcting myopia subepithelial PRK (SPRK, LASEK) varying degrees (patent of Ukraine № 19350 of 15 December 2006). Improved method , SPRK compared with a standard, allows the early postoperative period is likely to reduce the intensity of 5,8±0,35 to 7,2±0,46 points (p<0,05) and duration of pain syndrome 29,2±0 75, against 32,2±1,1 hours (p<0,05), and reach the cornea reepithelization 4 day in 95,14±1,3% to 87,95±1,17% of eyes (p<0,05). In the late period - provides less expressive HDB, respectively, in subgroups with low degrees of myopia 0,16±0,12 and 0, 34±0,11, (p <0,05), medium-0,19±0,10 and 0,35±0,09, (p <0,05), and high-0,79±0,19 and 0,93±0,19, (p<0,05). "Haze" of cornea frequency decreased from 46,5% to 2,8% (p<0,05) after SPRK and improved from 57,2% to 7,8% (p<0,05) after a standard SPRK. In the remote period (2 years) "haze" of cornea frequency, respectively, 1,9±1,9% and 7,6±2,6% (p<0,05). In the subgroup with a high degree myopia regression refractional marked effect, respectively, to 2,42 diopters. and 3,53 diopters., (p<0,05), and USVA decreased to 0,32±0,03 and 0,21±0,09 (p<0,05). Improved SPRK performed improved method leads to a reduction of the recovery of visual functions in patients, most of which are in working age.
