To evaluate the lens thickness, anterior cortex space, nucleus thickness, and posterior cortex space in cataractous eyes and compare them with those in eyes of younger patients with clear lenses.
Private practice, Lynwood, California, USA.
Retrospective observational study.
The study evaluated a group of cataractous eyes and compared them with a group of eyes of younger patients with clear lenses. All measurements were performed with a biometer (Lenstar LS 900).
The cataractous group (200 eyes) had a greater mean lens thickness (4.65 mm ± 0.41 [SD]) than the control group (80 eyes) (4.09 ± 0.33 mm). The mean measured values for the cataractous groups and control groups were 0.84 ± 0.21 mm and 0.35 ± 0.11 mm for anterior cortex space, 3.31 ± 0.25 mm and 3.27 ± 0.27 mm for mean nucleus thickness, and 0.51 ± 0.16 mm and 0.48 ± 0.13 mm for mean posterior cortex space, respectively. Anterior cortex space, nucleus thickness, and posterior cortex space correlated positively with lens thickness (r
= 0.69, r
= 0.69, and r
= 0.59, respectively). Lens thickness, anterior cortex space, nucleus thickness, and posterior cortex space showed a weak inverse correlation with axial length (r
= 0.06, r
= 0.08, r
= 0.10, and r
= 0.10, respectively) and an inverse correlation with anterior chamber depth (r
= 0.57, r
= 0.43, r
= 0.42, and r
= 0.22, respectively). Lens thickness showed a positive correlation with age (r
= 0.28), as did the anterior cortex space (r
= 0.32) and posterior cortex space (r
= 0.26), but nucleus thickness did not show a positive correlation (r
Lens thickness increased with age and with cataract formation and was mostly attributable to an increase in the anterior cortex space.
