Study Details

Brief summary:

The purpose of this study is to evaluate and compare the potential refractive outcomes using the Argos 1.5 biometer in the surgical planning for cataract extraction to that obtained from IOLMaster 700. Both devices are used as standard of care in surgical planning optimization for patients undergoing cataract surgery.
