title: [The advance and regression of the cataract operation].
abstract: In modern cataract surgery the introduction of akinesia, the corneal incision, the intracapsular extraction with forceps or cryo-stick, the zonulolysis and measures against complications and the optic correction of unilateral cataract with contact lenses can be seen as definite advances. Critically seen, the use of the operating microscope for senile cataract is not necessary, as the binocular loupe is fully sufficient. In the same way the selective use of zonulolysis - but not after the age of 55 - and of the cryo-stick - only on a stretched lans capsule is advised. Also the artificial pupillary lens is not recommended because of the excellent functional results of the contact lens. The same argument applies to emulsification of the crystalline lens. Also, from our experience, the routine use of antibiotics is not necessary. As well as the actual operation methods, including premedication, the methods used to avoid complications are finally and thoroughly discussed.
