Materials and Methods: In this study, 160 patients aged 7-73 years were divided into four groups according to age: Group 1 (7-18 years, n=33), Group 2 (19-44 years, n=39), Group 3 (45-60 years, n=60) and Group 4 (61-73 years, n=28). Central corneal thickness (CCT), anterior chamber depth (ACD), lens thickness (LT), and axial length (AL) measurements obtained by non-contact optical low coherence refractobiometry from 160 emmetropic eyes were analyzed.
Results: Gender distribution, mean spherical equivalent and CCT values were comparable across groups (p=0.192, p=0.124 and p=0.638, respectively). Mean ACD was higher in Group 1 (3.80±0.24 mm) than Group 2 (3.57±0.29 mm), Group 3 (3.52±0.37 mm) and Group 4 (3.50±0.43 mm), (p=0.001). Mean LT was lower in Group 1 (3.41±0.25 mm) than Group 2 (3.72±0.31 mm), Group 3 (4.04±0.43 mm) and Group 4 (4.20±0.43 mm). Also, it was lower in Group 2 than Group 3 and 4 (p <0.001). Mean AL was 23.35±0.70 mm in Group 1, 23.52±0.69 mm in Group 2, 23.59±0.84 mm in Group 3 and 24.03±0.72 mm in Group 4 with only difference between Group 1 and 4 (p=0.006).
Conclusion: ACD was lower while LT and AL were higher in emmetropic eyes of patients aged> 61 than those of children aged<18 years
