NCT05052242

Brief Summary

Purpose: To investigate agreement between 2 swept source OCT biometers, IOL M.aster700 and Anterion, in various ocular biometry and intraocular lens (IOL) calculations of primary angle-closure disease (PACD). Methods: This was a prospective study conducted in a tertiary eye care centre involving biometric measurements obtained with 2 devices in phakic eye with diagnosis of PACD. Mean difference and intraclass correlation coefficient (ICC) with confidence limits were assessed, and calculations of estimated residual refraction of the IOL were analysed using Barrett's formula.
