PURPOSE: To study the relationship between objective metrics for quantifying crystalline @entity2092 with @entity227 and phacodynamics parameters in age-related nuclear @entity231 . METHODS: A total of 51 eyes (34 @entity1 ) with age-related nuclear @entity231 had phacoemulsification. The Dysfunctional Lens Index (0 to 10 points) was measured by a @entity16039 -tracing aberrometry (iTrace Visual Function Analyzer; Tracey Technologies, Houston, TX). The average lens density (0 to 100) was evaluated using a rotating Scheimpflug system (Pentacam HR; Oculus Optikger  te GmbH, Wetzlar, Germany), and the nuclear opalescence score was subjectively assessed using the Lens Opacities Classification System III (LOCS III). The different parameters for evaluating crystalline @entity2092 were correlated with preoperative corrected distance visual acuity (CDVA) and cumulative dissipated energy (CDE). RESULTS: There was a negative linear correlation between the Dysfunctional Lens Index and the LOCS III nuclear opalescence and Scheimpflug-measured average density (r =-0.728 and r = -0.771, respectively; both P < .01). The preoperative CDVA was correlated with the Scheimpflug-measured lens nuclear density value (r = 0.612, P < .01) and Dysfunctional Lens Index score A (r =-0.670, P < .01). The CDE was more strongly correlated with Dysfunctional Lens Index and Scheimpflug-derived average density (r =-0.744 and r = 0.700, respectively; both P < .01) than with LOCS III nuclear opalescence (r = 0.646, P < .01). CONCLUSIONS: The Dysfunctional Lens Index was correlated with the Scheimpflug-measured average density, subjective lens grading, and preoperative CDVA. This metric also presented the highest correlation with phacodynamics. Correlation with other clinical measures related to @entity227 and impairment are still needed.
