PURPOSE: To study the distribution of ocular biometric parameters utilizing a swept-source
optical coherence tomography (SS-OCT) biometer in adult candidates for cataract surgery.
Design: A retrospective cross-sectional study
METHODS: SETTING: A single-center analysis of consecutive eyes measured with the IOLMaster 700 SS-OCT biometer at a large tertiary medical center between February 2018 and June 2020.
RESULTS: 3836 eyes of 3836 patients were included in the study. The mean age was 72.3±12.8 years and 53% were females. The mean biometric values were: total corneal power (44.17±1.70D), total corneal astigmatism (TCA) (1.11±0.87D), mean posterior keratometry (- 5.87±0.26D), posterior corneal astigmatism (-0.26±0.15D), axial length (AL) (23.95±1.66mm), anterior chamber depth (ACD) (3.18±0.42mm), lens thickness (LT) (4.49±0.47mm); white-towhite distance (WTW) (11.92±0.44mm), central corneal thickness (CCT) (0.54 ± 0.04mm), angle alpha (0.49±0.17mm), and angle kappa (0.34±0.17mm). There were sex-related differences in all biometric parameters with the exception of LT (P=.440), angle kappa (P=.216), and corneal astigmatism (P=.103). Biometric parameters demonstrated correlations between AL, WTW distance, ACD, and LT (P<.001). Age correlated with all parameters (P<.001), with the exception of CCT and posterior keratometry. Angle alpha and angle kappa magnitudes also correlated (P<.001). The prevalence of patients with TCA ≥0.75D, 1.0D and 1.5D were 59.1%, 43.4% and22.6%,respectively.
CONCLUSIONS: Age significantly correlated with most of the biometric parameters and significant differences between sexes were noted. Furthermore, the high prevalence of TCA and relatively large angle alpha and angle kappa magnitudes were noted among subjects. These data can be relevant in planning local and national health economics.
