Randomized Trial Comparing Prediction Accuracy of Two Swept Source Optical Coherence Tomography Biometers
Completed
Conditions studied: Cataract
In brief
To assess if the Alcon Argos Biometer utilizing the Barrett Universal II formula for IOL calculations can give a non-inferior outcome when compared to the Zeiss IOL master 700 utilizing the (PCA) with the Barrett Universal II (TK) formula, when comparing the (mean absolute prediction error of the predicted target spherical equivalencies).
