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\u2009\u00b1\u20090.19, 1.04\u2009\u00b1\u20090.21 and 1.06\u2009\u00b1\u20090.21\u2009m\/s, respectively, for males and 0.84\u2009\u00b1\u20090.22, 0.91\u2009\u00b1\u20090.24 and 0.92\u2009\u00b1\u20090.25\u2009m\/s, respectively, for females. The increase after surgery was significant in both groups at 7 months (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05). 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\u2009\u00b1\u200911.4% of normal vision with a 3\u00b0 visual field and 92.4\u2009\u00b1\u200912.3% of normal when counting fingers. Initial velocity was 89.1\u2009\u00b1\u200914.6% of normal vision with a 3\u00b0 visual field and 92.7\u2009\u00b1\u200911.6% of normal when counting fingers. There was a significant difference between normal and impaired visual function (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.05).
