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.
从制造商标注的屈光度角度对55枚Hellgrebe 2型（35枚）和Fiodorov型（20枚）前房人工晶状体进行了验证。前表面屈光度的测量使用70型测量仪（卡尔·蔡司，耶拿，民主德国）以及一个专门设计的适合消毒的塑料比色皿进行。Hellgrebe 2型晶状体的平均偏差为-1.42屈光度，Fiodorov型晶状体的平均偏差为0.23屈光度。Hellgrebe 2型晶状体不符合国际公差质量标准±0.25屈光度。
