Age-related Cataract Clinical Trial
Official title:
Dysfunctional Lens Index Serves as a Novel Surgery Decision Maker for Age-related Cataracts
To study the correlations among the dysfunctional lens index (DLI), Lens Opacities Classification System III (LOCS III) nuclear opalescence grading score, preoperative corrected distance visual acuity (CDVA), the objective scatter index (OSI) and Scheimpflug based average lens density in age-related cataracts. To investigate the potential of the DLI as a novel surgery decision maker via the Operating Characteristic (ROC) curve analysis.
