Purpose

To evaluate ocular biometric parameters according to age and axial length measured by swept-source optical coherence tomography biometer in patients undergoing cataract surgery

Setting

Department of Ophthalmology, Seoul National University Hospital (SNUH), Seoul, Korea

Methods

This study included 5273 eyes of 5273 Korean patients who underwent ocular biometry by IOLMaster 700 for cataract surgery at SNUH from November 2019 to December 2021. Age, sex and ocular biometric values including axial length (AL), standard corneal power (K), posterior corneal power (PK), total corneal power (TK), standard keratometric astigmatism (KA), posterior corneal astigmatism (PCA), total corneal astigmatism (TCA), central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), white-to-white distance (WTW), angle alpha and angle kappa were reviewed. Correlation between age, axial length and other ocular biometric values was analyzed by Pearson’s correlation analysis.

Results

The mean ± SD age was 66.1 ± 12.8 years and 62% were female. Age showed negative correlation with ACD (r=-0.357), AL (r=-0.344), WTW (r=-0.250), CCT (r=-0.121) and PK (r=-0.054), and positive correlation with LT (r=0.484), angle alpha (r=0.194), TK (r=0.137), K (r=0.129), TK-K (r=0.110) and angle kappa (r=0.071). With age, KA and TCA changed from with-the-rule (WTR) to against-the-rule (ATR) astigmatism. PCA was ATR regardless of age, but the magnitude of astigmatism decreased with age. AL showed positive correlation with ACD (r=0.503), PK (r=0.339), WTW (r=0.285), TK-K (r=0.075) and CCT (r=0.071), and negative correlation with K (r=-0.342), TK (r=-0.334), LT (r=-0.288), angle alpha (r=-0.220) and angle kappa (r=-0.040).

Conclusions

In Korean patients with cataract, age showed a significant correlation in the order of LT, ACD and AL. With age, TKA changes from WTR to ATR, which is mainly affected by changes in AK. AL showed a significant correlation in the order of ACD, K, PK, and TK.
