Accuracy of Topography Guided Automatic Marking of the Intraocular Lens (IOL) -Axis
Sponsor: Frank Bochmann
Summary
In cataract surgery, the opaque lens is replaced by an artificial intraocular lens. The procedure also allows for correction of an refractive error such as myopia, hyperopia or astigmatism. In case of correction of an astigmatism, the axis intraocular lens has to be alligned to the axis of the corneal astigmatism. There are serveral options, the intendet position of the axis can be marked on the cornea, either manually using ink and a special caliper or with an automatic laser device. The aim of this study is to assess the accuracy of topography guided automatic marking of the intended IOL-axis in toric IOL-implantation in femtosecond laser assisted cataract surgery (FLACS)

Marking of the intended axis of IOL-Implantation manually with an ink and marking device on the surface of the eye
The marking of the intended implantation axis of the interocular lens will be marked in all patients with topography guided in the corneal stroma with laser and in addition manually with a caliper and ink on the corneal surface
