Brief Summary
The purpose of this study is to determine if the keratometric functions of the VERION Image Guided System are comparable to those of established keratometric devices (IOLMaster 500, Pentacam HR, LenStar LS900). Calculated intraocular lenses (IOLs) are compared as a clinical consequence of the biometric measurement for IOLMaster 500, LenStar LS900 and VERION Image Guided System. In addition the comfort and duration of examination in the different devices is evaluated.
