Comparative Analysis of Pre- and post-operative Best Corrected Visual Acuity (BCVA) and Percentage of Improvement Across Age Groups. The dual-axis graph presents Best Corrected Visual Acuity (BCVA) measured in LogMAR before (blue bars) and after (orange bars) cataract surgery, alongside the percentage of visual acuity improvement (red line), across five distinct age groups. The left vertical axis corresponds to the BCVA values, with lower scores indicating better visual acuity. The right vertical axis denotes the percentage of BCVA improvement, with higher values representing greater visual recovery. Error bars indicate the standard deviation (SD) within each age group, providing a measure of variability around the mean BCVA scores. Statistical significance between consecutive age groups, following Bonferroni correction for multiple comparison, is marked by the respective p-value, illustrating the differential impact of surgery on visual outcomes by age.
