Intra-correlations between cataract density based on Scheimpflug image, phacodynamics, surgery duration, and endothelial cell loss after phacoemulsification
Purpose: To assess intra-correlations between lens density based-on Scheimpflug Imaging System, power used during surgery, surgery duration, and endothelial cell loss in eyes with nuclear cataract. Setting: Department of Ophthalmology, King Fahd Hospital of the University, Alkhobar, Saudi Arabia. De...

Setting: Department of Ophthalmology, King Fahd Hospital of the University, Alkhobar, Saudi Arabia. Design: Prospective cross-sectional observational study.

A strong correlation was observed between the degree of endothelial cell loss and phacodynamic parameters but not with the length of the procedure.
