Spatial contrast sensitivity (SCS) was analyzed using mesopic (light off 10 candel/m2) and intensive illumination (light on 20,000 candel/m2) and corneal higher-order aberrations (CHOA) in 29 children with high-grade unilateral hypermetropia complicated by severe and moderate amblyopia after LASIK, Epi-LASIK, and intra-LASIK surgery. The values were comparable in the groups following 6 months under the intensive illumination and mesopic conditions at low and moderate frequencies. Under mesopic conditions, at high spatial frequencies, the values of SCS, as compared with the baseline values of 0.32 log units, the values of SCS were 0.34 log units after LASIKC (p > 0.05), 0.86 log units after intra-LASIK (p < 0.001), and 1.09 log units (p < 0.001). CHOA increased by 2.7 times after LASIK, by 1.45 times after intra-LASIK and epi-LASIK The operations showed an average of 1.5-fold improvement in children as compared with the baseline values. |
