[Results with automatic refraction (author's transl)]

Hundred eyes of young patients with an average age of 25 years were measured with two refraction methods: 1. subjectiv refraction and 2. automatic refraction with the "Dioptron". The results of refraction and visual acuity before and after cycloplegia were compared. As for the spherical aquivalents we found a very good correlation between both methods (r - 0,98). The "Dioptron" printed out stronger cylindric powers as were found with the subjectiv refraction. Furthermore it could be shown that the stronger the cylindric power the smaller the axial deviation between subjectiv and automatic refraction. We believe that the automatic refraction with "Dioptron" is a good screening method, which cannot replace fine subjective adjustments, but complements them by serving as a good starting point for the refractive procedure.
