Forty one patients aged 29 to 82 years were subjected to cataract extraction in ambulatory conditions. Fifty eyes were operated, among them 33 with implantation of a posterior chamber artificial lens. In cases of a lack of opacities in the cortex layers their structure was loosened before the operation by a YAG laser. The lens was extracted mainly by phacoemulsification. The ambulatory procedure did not result in any undesirable consequences. The profits of operation performed in such a way were stressed. Attention was called to the fact that by prudent qualification of patients and a careful selection of surgical methods the risk of this kind of treatment is not greater than in stationary conditions.

[A stereoscopic device for simultaneous imaging of the fundus oculi].

A stereoscopic countershaft worked out by the authors is cooperating with stereoophthalmoscope model 110. The element of the binocular with its original lenses used in the countershaft was supplemented with prisms which rectify the distance of the geometrical centres of the pictures on the frame of a 35 mm film. A vertical central screen prevents the half-pictures to overlap. The length of the optical path beyond the stereoophthalmoscope amounts 130 mm. Simultaneous stereograms of the eye fundus received by means of this construction are characterized by a transversal enlargement 1.3 X, 1.65X and 3.3X.

[Simultaneous stereograms of the fundus oculi].

Stereophotograms and stereoangiograms of the fundus in selected pathological conditions are presented. The simultaneous performance of fundus stereograms are devoid of drawbacks and faults encountered in stereoscopic pictures registered in double time. A major consistency of the half-pictures results from an identical utilization of the focal depth and an uniform illumination in one exposure. In the fluorographic examination this method is a method of choice in the registration of a spatial picture throughout the examination.
