  Purpose

It is planned to implant the intraocular lenses XL Stabi ZO and Invent ZO into the eyes of patients for whom a cataract operation is medically indicated. The lenses are marketed and CE certified. Their implantation is clinical routine.

In the trial the accuracy of prediction of target refraction and the difference between calculated and measured contrast vision will be examined for both lens types.
