Brief summary

Primary objective of this study is to evaluate the level of agreement of two keratometry modules, the IOLMaster and the Verion Reference Unit, in terms of keratometric values and IOL power calculation.

Detailed description

Participants were enrolled from the Cataract & Presbyopia Service of the University General Hospital of Alexandroupolis in a consecutive-if-eligible basis. Apart from keratometric values, IOL power calculations will be compared for 8 IOL models (Acrysof SN60WF, SN60AT, SN6ATx, TFNT00, TFNTx0, SV25T0, SV25Tx and Tecnis ZCB00) using 4 formulas (SRK/T, Holladay 1, Hoffer Q and Haigis).
