Abstract

Purpose

To evaluate the relation between ocular biometry and anthropometric parameters in Korean adults with cataracts.

Methods

The preoperative medical data of 150 eyes (150 patients) who underwent cataract surgery from November 2015 to March 2016. Anthropometric parameters include height, weight and body mass index (BMI). Ocular biometry includes axial length, anterior chamber depth, corneal curvature, lens thickness and central corneal thickness. The relation between ocular biometry and anthropometric parameters was evaluated using linear regression analysis.

Results

The mean age was 67.44 ± 10.83 years. The mean height, weight and BMI were 157.24 ± 9.16 cm, 60.50 ± 10.18 kg and 24.47 ± 3.59 kg/m². The mean axial length, anterior chamber depth, corneal curvature, lens thickness and central corneal thickness were 23.51 ± 0.80 mm, 3.23 ± 0.42 mm, 44.49 ± 1.33 diopter, 4.44 ± 0.42 mm and 534.64 ± 31.90 μ m. The height showed a significant positive relationship with axial length and anterior chamber depth and a significant negative relationship with average corneal curvature. However, there was no significant relationship with the central corneal thickness or lens thickness. The weight showed significant positive relationship with axial length. BMI was not related to any anthropometric parameters. Age showed a significant positive relationship with average corneal curvature and lens thickness and a negative relationship with height and anterior chamber depth.

Conclusions

As height increases, the axial length and the anterior chamber depth increase and the corneal curvature become flatter. As age increases, the anterior chamber depth becomes shallower, the corneal curvature becomes steeper and the lens thickness increases.
