Slit-lamp lens images, Pentacam and IOL-Master 700 images were collected in patients with dilated pupil before cataract surgery, and phacoemulsification parameters on the Centurion phacoemulsification machine (Alcon) screen were recorded. Spearman correlation analysis was used to analyze the correlation between lens nuclear density and phacoemulsification parameters based on SS-OCT and Scheimpflug techniques.
