Analysis of ocular biometrics in cataract patients aged 40 and above in Suzhou, China.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Purpose: This cross-sectional study investigated the distribution of ocular biometric parameters in cataract patients aged ≥40 years from East China, with a specific focus on age- and sex-related differences and their correlations. Given the paucity of large-sample reference data for this population, we aimed to establish a localized framework to support precise surgical planning in refractive cataract surgery. Methods: This retrospective study consecutively enrolled patients aged ≥40 years who underwent cataract surgery at Lixiang Eye Hospital of Soochow University between January 2019 and September 2022. Axial length (AL), anterior chamber depth (ACD), corneal curvature (K1, K2), corneal astigmatism, intraocular lens (IOL) power, and intraocular pressure (IOP) were assessed. Non-parametric tests, Spearman correlation analyses, and multivariable linear regression were applied using SPSS 22.0 (IBM Corp.). Results: A total of 3,311 cataract patients (1,458 males, 1,853 females) were included. Female eyes had shorter AL and shallower ACD, but steeper corneal curvatures (K1, K2) compared to male eyes (all Conclusion: This study provides comprehensive, large-sample reference data on ocular biometric parameters for cataract patients in East China. We identify distinct age- and sex-specific patterns, particularly the non-linear age-related changes in corneal astigmatism and the sex-specific differences in astigmatism axis distribution. These findings offer actionable benchmarks for preoperative IOL selection, astigmatism management strategies, and patient counseling, thereby contributing to optimized refractive outcomes in cataract surgery.
