Analysis of preoperative ocular optical parameters in patients with cataract

Table 2 Comparison of higher-order aberrations in the anterior corneal surface of right eyes across different age groups

Age group (years)	Anterior surface (μm)	Posterior surface (μm)	Total cornea (μm)
20–40	0.189	−0.146	0.146
41–60	0.282	−0.139	0.252
61–80	0.341	−0.119	0.338
Over 80	0.354	−0.108	0.362
Spearman’s correlation coefficient	0.50	0.43	0.57
P	<0.001	<0.001	<0.001

Note: Data were tested for normality using the Kolmogorov–Smirnov test. Since the data followed a normal distribution (p > 0.05 for all variables), analysis of variance (ANOVA) was applied for group comparisons
