Abstract
Purpose:
To evaluate the relationship between age, axial length (AL), anterior chamber depth (ACD) and corneal steepness (K) in adult Korean population.
Methods:
Medical records of 800 patients (800 eyes) who underwent cataract surgery were reviewed retrospectively. The univariate and multivariate analysis of ocular biometric data including AL, ACD and K were conducted according to age.
Results:
The univariate analysis showed increase in age has significant correlation with decrease in AL (P<0.001), ACD (P<0.001) and steeper K (P<0.001). The K value has a negative correlation with AL (P<0.001). In multivariate analysis, increase in age showed a significant association with decrease in AL (P<0.001) and ACD (P<0.001), while association between age and K was not significant (P = 0.398). The negative correlation between AL and K remained significant in multivariate analysis (P<0.001).
Conclusions:
Increase in age had significant association with decrease in AL and ACD. The AL and K had negative correlation. The mechanisms underlying these phenomena are discussed.
