Die Katarakt (grauer Star) ist heutzutage einer der häufigsten Gründe für vermindertes Sehvermögen und tritt mit zunehmendem Alter bei den meisten Menschen auf. Sie ist zudem weltweit die häufigste Ursache für Erblindung.
Betroffene realisieren oft nicht, dass sie an einer Katarakt erkrankt sind, bis sich ihre Sehqualität drastisch verschlechtert und ihr Alltagsleben dadurch erschwert wird. Unbehandelt kann sie sogar zur vollständigen Erblindung führen. Glücklicherweise kann eine Katarakt heutzutage leicht und effektiv mit einem sicheren Routineverfahren behandelt werden. Die Entfernung der getrübten Augenlinse und das Einsetzen einer Intraokularlinse (IOL) werden derzeit weltweit über 20 Millionen Mal im Jahr durchgeführt.1 Erfahren Sie mehr über moderne Technologien zur Behandlung von Katarakt.
