[The prognostic value of the laser-interference-fringe-test with cataract patients (author's transl)].

The retinal visual acuity of 198 cataractous eyes was tested with interference-fringes and compared with the post-operative visual acuity. A new method of creating interference-fringes was used. The interference-fringe technique showed its special clinical value with immature cataracts. It is of certain value also with premature cataracts. With mature and hypermature cataracts no results of clinical value could be obtained. The method seems to have its value with congenital and juvenile cataracts.
