1. ZO a KC u 110 pacientů (110 očí s myopií v rozmezí od -0,25 dpt do -12,0 dptrozdělených podle výše myopie do 4 skupin) byly vyšetřeny vybranými metodamipřed a 12. měsíc po FRK. V kontrolní skupině bylo testováno 20 emetropů.2. Předoperační hodnoty KC a NKZO byly ve všech skupinách myopie, s výjimkouskupiny A, statisticky významně nižší (p

Overview
1. 110 myopes undergoiyng photorefractive keratectomy (PRK) with refractionfrom - 0,25 D to -12,0 D were divided into 4 groups: A: upto -2.75 D, B: -3.0 D to -5.75D, C: -6.0 D to -8,75 D and D: -9.0 D to -12,0 D. BCVA using the computerized methodwith Landolt rings and CS using an adjustment method with ascendent anddescendent approach to treshold contrast adaptation on a computerized systemof the Contrast sensitivity 8010 type were examined in patients before and 1 yearafter PRK. 20 emmetropes of the same median age were evaluated as a controlgroup.2. Preoperative BCVA and CS in myopes of all four groups was significantly lower(p
