Purpose
To evaluate the relationship between the age, axial length, anterior chamber depth, corneal steepness and corneal thickness.

Methods
Medical records of 652 patients (652 eyes) who underwent cataract surgery at Kong Eye Center were reviewed. Data including age and ocular parameters including axial length, anterior chamber depth, corneal steepness and corneal thickness were collected and analyzed using univariate and multivariate analyses.

Results
Univariate analysis showed increased age has significant correlation with shorter axial length (P<0.001) and anterior chamber depth (P<0.001), increased corneal steepness (P<0.001) and thickness (P = 0.031). Increased corneal steepness has significant correlation with decreased axial length (P<0.001) and decreased anterior chamber depth (P<0.001). Multivariate analysis revealed that increased axial length has significant correlation with decreased corneal steepness (P<0.001) and increased anterior chamber depth (P<0.001). Although the association between age and corneal steepness was not significant (P = 0.132), increased age was significantly related to decreased anterior chamber depth (P<0.001), decreased axial length (<0.001) and increased thickness (P = 0.001).

Conclusion
Increased axial length has significant correlation with increased anterior chamber depth and decreased corneal steepness. Increased age has significant association with increased corneal thickness and decreased anterior chamber depth.
