[Twenty-two year's experience with intraocular lenses (author's transl)].

The employment of the intraocular lens is an acceptable procedure in selected cases. It has great optical and practical advantages over conventional treatment. In the evaluation of suitable cases, clinical considerations, indications and contraindications are of major importance. The extraction of the opaque cataractous lens from the human eye is an eternally new, ever exciting operation which always has challenged the skill of the ophthalmic surgeon. It is not easy and it always involves a risk. The additional demands of technique incurrent in the insertion of the intraocular pupillary lens render the operation still more difficult and increase the risks. The results presented and the advantages achieved justify, in my opinion, the use of an intraocular lens in selected cases of cataract extraction.
