The aim of this study was to evaluate the possibility of evaluation of optimal hyperopic correction based on visual evoked potential (VE P) examination results in children that do not cooperate. There are relatively few studies that evaluated the correlation between visual acuity and especially in young hyperopes. We examined 80 children (160 eyes) with hyperopia, divided into two groups: children that were cooperative during examination and children that could not cooperate with the examiner. Upon determination of the eye refractive state by other objective methods, the prescribed refraction was checked by following the change in VE P P100 wave amplitude and prescribed the correction for which these values were highest. The first VE P curve was recorded without any correction, then more VE P curves were recorded after increasing correction between +1.0 and +6.0 D, in the range found by retinoscopy, with 1 D step. The correction values that caused VE P curves with highest amplitude and shortest P100 wave latency were recorded. In conclusion, the VE P curve parameters were confirmed to depend on the refractive state of the eye.
