[Measurement of the power of artificial intraocular lenses].
Fifty five anterior chamber artificial lenses of the Hellgrebe model 2(35) and Fiodorov's (20) were verified from the angle of the power quoted by the producer. The measurement of the length of the frontal power were performed by means of a measurer 70 (Carl Zeiss, Jena, GDR) and by a specially designed plastic cuvette suitable for sterilization. The mean deviation amounted -1.42 dptr. for the Hellgrebe's 2 lens and 0.23 dptr. for Fiodorov's lens. The Hellgrebe type 2 lenses do not answer the international quality norms of tolerance +/- 0.25 dptr.
