Popis: AIM: To analyze the correlations among parameters from iTrace visual function analyzer, Pentacam 3D anterior segment analysis system and lens opacities classification system(LOCS)Ⅲ in the assessment of lens opacity of age-related cataract(ARC)patients.METHODS: A prospective cross-sectional study. A total of 104 ARC patients(104 eyes)in the department of ophthalmology of our hospital from May to August, 2021 were included. The cataracts of patients were graded based on LOCSⅢ using a slit-lamp. Opacity map grade(OMG)and dysfunctional lens index(DLI)were obtained by iTrace. Pentacam nucleus staging(PNS)and Scheimpflug images of lenses were acquired by Pentacam. The regional integrated density(IntDen)of Scheimpflug images was obtained by ImageJ. The normality and correlations of parameters were analyzed by SPSS 26.0.RESULTS: All the parameters were normally distributed except 3mm IntDen and IntDen of 6mm posterior subcapsular region. PNS positively correlated with nuclear color(NC)and nuclear opalescence(NO)(r=0.521, 0.440, all P
