[Retinometer examinations in cataract patients (author's transl)]

Using the retinometer after Rassow and Wolf (Rodenstock) retinal visual acuity was determined preoperatively in 71 patients with senile cataract. In general the measured value corresponded with postoperative visual acuity. In 26 of the 71 cases, however, there was a discrepancy of more than 50% between the two measurements. This discrepancy was found in patients with clear ocular media almost as frequently (42 of 126 eyes).
