AB Background: Due to the increasing use of contact lenses (CL) and the interest in ocular and body size relationships, this study aimed to compare measurements from two biometers (contact ultrasonic EchoScan US-800 and non-contact optical Lenstar LS900) with and without CL and to explore the relationship between ocular and body biometric parameters.Design and Methods: This cross-sectional study measured ocular biometry using two biometers along with their body height and right foot length in 50 participants. Differences between biometry data from the two devices were compared and correlations between ocular and body biometric values were analyzed.Results: All parameters showed interbiometric differences (p≤0.030), except crystalline lens thickness during CL wear (p=0.159). Comparing measurements with and without CL, differences were observed in axial length (p<0.001), vitreous length measured by optical biometer (p=0.016), and anterior chamber depth by ultrasonic biometer (p<0.016). Lens thickness remained unaffected (p≥0.190). Body height and foot length were correlated with anterior chamber depth, vitreous length, and axial length (p≤0.019, r≥0.330). Most biometric parameters were correlated among them using both devices (p≤0.037, r≥0.296).Conclusions: These biometers are not interchangeable and CL affects measurements. Body height and foot length correlate with ocular dimensions, and most ocular biometric values correlate positively.
