ABSTRACT
Using Rodenstock's Refraktometer refractometry was done on 314 hyperopic children (3--14 years) first after treating with Atropine and some weeks later after Cyclopentolat-hydrochlorid. 53,1% of them showed higher hyperopia after Atropine than after Cyclopentolat, the maximum in difference was 1,75 dptr. In another group of children with Cyclopentolat-treating the residual accommodation was determined by four different methods (Refactometer, Apparatus of Schober, Phoropter in a distance of 5,0 and 0,4 mtrs). The results show a minimum of accommodation 45 minutes after application of the drops under special conditions. These conditions are reported as well as a method of correction of hypermetropia due to the values of refractometry or residual accommodation.
