Introduction: To assess gender, age, and diabetic status-associated differences in the ocular biometric parameters and demographics among patients presented for cataract surgery in a hospital setting.
Methods: This retrospective cross-sectional study analysed 1007 eyes undergoing cataract surgery at Chattogram Lions Charitable Eye Institute and Hospital, Bangladesh, between November 2023 and November 2024. Biometric parameters, axial length (AL) and keratometry (K) were measured using the IOL Master 700. Demographic and systemic variables (age, sex, diabetes status) were obtained from medical records. Associations were assessed using t-tests, ANOVA, Pearson correlations, and multivariate regression.
Results: The mean age of the cataract patients was 60.9 ± 10.6 years; 53.1% were female. Mean AL was 23.13 ± 1.09 mm, mean K1 was 44.60 ± 1.70 D, and mean corneal astigmatism was 0.89 ± 0.52 D. Males had significantly longer AL than females (23.40 vs. 22.99 mm, p < 0.05). Diabetes was associated with shorter AL, particularly in females. Keratometry values correlated negatively with AL (r = –0.36, p < 0.001). Astigmatism increased with age (p < 0.05), with against-the-rule being more dominant in older and younger age groups. Females had significantly steeper corneas than males (mean difference 0.74 D, p < 0.05).
Conclusions: Gender, diabetes, and corneal curvature were significant predictors of axial length, whereas age strongly influenced the type of astigmatism. These findings have direct clinical implications for IOL power calculation and emphasize the importance of incorporating demographic and disease-specific considerations into cataract surgery planning.
