Correlations of nuclear density measured using long-range swept-source optical coherence tomography image combined with ImageJ software (NDSS-OCT), nuclear density measured using Pentacam Nuclear Stage function (NDPNS), respectively, with Lens Opacities Classification System III (LOCS III) nuclear grading scores, including nuclear opalescence (NO) and nuclear colour (NC) and logarithmic minimal angle resolution (logMAR) best-corrected visual acuity (BCVA)
| Correlation coefficients | NO | NC | BCVA (logMAR) | NDSS-OCT |
| NDSS-OCT | 0.831 | 0.873 | 0.655 | – |
| NDPNS | 0.830 | 0.759 | 0.519 | 0.891 |
All correlations were analysed using the Spearman's correlation analysis. All p values were <0.001.
