In refractive surgery the removal of the natural lens followed by implantation of an artificial intraocular lens has been an established method to treat refractive errors. The term "clear lens exchange" separates this approach from cataract surgery, where a cloudy lens has to be removed. With regard to currently available intraocular lens technologies, there is a wide range to correct myopia, hyperopia as well as astigmatism. Trifocal or extended depth-of-focus lenses (EDOF) even with a toric component offer the patients a potential benefit to further address presbyopia, respectively. Furthermore, the surgery in combination with Femtosecond laser-assistance offers more precision to this highly elective approach.This article provides an overview about currently available procedures and implants to correct presbyopia and refractive errors. A thorough evaluation of risk and benefit for each patient group is given with regard to recent guidelines of the German Commission for Refractive Surgery (KRC).
Die operative Entfernung der eigenen Linse mit anschließender Implantation einer Kunstlinse ist ein etabliertes Verfahren in der refraktiven Chirurgie. Der Artikel beschreibt die unterschiedlichen Verfahren und Intraokularlinsensysteme unter Berücksichtigung der aktuellen Empfehlungen der Kommission für Refraktive Chirurgie. Auf die Komplikationsmöglichkeiten der einzelnen Techniken und Intraokularlinsen wird in den Unterabschnitten hingewiesen.
