- Primary Outcome Measures
Name Time Method The primary endpoint of this study is to compare the ocular biometry measurements captured by Elisar NOA and IOLMaster 500 device. The measured values will be compared with the limits indicated in the protocol.Timepoint: 12 weeks
- Secondary Outcome Measures
Name Time Method The secondary endpoint of this study is to compare the predicted refractive error for the calculated IOL power of each patient in both Elisar NOA and IOLMaster 500 where the difference in the error is not more than 1D.Timepoint: 12 weeks
