N2 - The aim of the present study was to measure gait velocity in cataract and simulated patients. The study was performed on 239 cataract patients, 115 age-matched subjects, and 11 simulated patients. We measured gait velocity and analyzed gait using a three-dimensional motion analysis system. Mean gait velocity before and 2 and 7 months after cataract surgery was 0.91 ± 0.19, 1.04 ± 0.21, and 1.06 ± 0.21 m/s, respectively, for males and 0.84 ± 0.22, 0.91 ± 0.24, and 0.92 ± 0.25 m/s, respectively, for females. The increase after surgery was significant in both groups at 7 months (P < 0.05). Gait velocity was significantly slower in cataract patients compared with controls before surgery, but no longer different after surgery. In simulated patients, mean velocity was 87.0 ± 11.4% of normal vision with a 3° visual field and 92.4 ± 12.3% of normal when counting fingers. Initial velocity was 89.1 ± 14.6% of normal vision with a 3° visual field and 92.7 ± 11.6% of normal when counting fingers. There was a significant difference between normal and impaired visual function (P < 0.05). The results demonstrate the close relationship between visual function and gait in cataract patients and simulated patients.
