Purpose: To measure ocular biometry and its correlates in an adult population. Materials and Methods: The measured biometric data included central corneal thickness (CCT), corneal power (K), anterior chamber depth (ACD), lens thickness (LT), vitreous chamber depth (VCD), axial length (AL), and spherical refractive error (SER) in 162 adult eyes. Results: The mean CCT was 506.7 ± 39.2 μm, mean K was: K1 = 42.50 ± 2.00 D, K2 = 43.50 ± 2.44 D, the mean AL was 24.2 ± 1.3 mm, ACD had a mean of 3.5 ± 0.6 mm, LT (mean of 3.9 ± 0.8 mm), VCD (mean of 16.4 ± 1.39 mm), and SER ranged from -10.00 D – +8.00 D. There were no significant correlations between the CCT and SER (r = 0.06, P = 0.44), LT (r = 0.06, P = 0.59), ACD (r = −0.12, P = 0.12), AL (r = −0.02, P = 0.98), and VCD (r = −0.05, P = 0.68). Pearson's correlation coefficient tests showed that AL was significantly positively correlated with ACD (r = 0.4, P < 0.001) and VCD (r = 0.73, P < 0.001) and negatively correlated with LT (r = −0.22, P < 0.05). A significant negative weak correlation was found between LT and ACD values (r = −0.22, P < 0.05). Conclusion: A thin CCT was observed among an adult Ghanaian population. CCT was found to be independent of AL. Correlation among ocular biometry showed that AL positively correlated with ACD and negatively correlated with LT.
