Abstract

Background: This study was conducted to investigate ocular biometry parameters in cataract surgery candidates in northern Tehran, Iran using OA-2000 biometry device. Methods: In this cross-sectional study, values of ocular biometry parameters, including axial length (AL), anterior chamber depth (ACD), mean corneal curvature (mean K), lens thickness (LT), corneal astigmatism (CA), and white-to-white (WTW) of 818 eyes with cataracts, were measured using the OA-2000 biometry device (Tomey, Nagoya, Japan). The participants were divided into six age subgroups, in 10-year intervals. Finally, the values of the biometry parameters were calculated, and the trend of changes was examined for both age and sex subgroups. Results: The mean± standard deviation (SD) of age of the participants was 63. 82 ± 13. 25 years. Mean ± SD of biometry parameters were as follows: AL, 23. 36 ± 1. 55 mm; ACD, 3. 09 ± 0. 40 mm; LT, 4. 45 ± 0. 55 mm; mean K, 44. 51 ± 1. 72 D; CA, 1. 06 ± 0. 94 D; and WTW, 11. 81 ± 0. 45 mm. Most of the parameters showed significant age-related changes in the total population. There was an increase in LT (P < 0. 001) and mean K (P = 0. 001), as well as a decrease in AL (P < 0. 001) and ACD (P < 0. 001) with age. Moreover, AL had a negative negligible correlation with LT (r =-0. 24, P < 0. 001) and mean K (r =-026, P < 0. 001), as well as a weak positive correlation with ACD (r = 0. 44, P < 0. 001). Conclusions: Our study revealed that the mean values of most biometric parameters varied across age and sex subgroups. Moreover, most of the parameters showed significant age-related changes in the total population.
