Assessment of Age-related Cataract using Scheimpflug Imaging System and its Correlation with Phacoemulsification Parameters [PDF]

Journal of Clinical and Diagnostic Research, 2020
Introduction: Phacoemulsification has become the preferred treatment for cataract removal throughout the world. Therefore, it is important to assess cataract pre-operatively which could lead to a better organised and customised operative plan.
