People of M\u0101ori, Pacific and Indian ethnicities presented at a significantly younger age (66.4, 65.9 and 67.9\u2009years, respectively) than those of Caucasian and Asian ethnicities (76.4 and 71.3\u2009years, respectively, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001). Advanced cataract was more likely in Pacific peoples and M\u0101ori than Caucasians. The mean axial length was longest in Asian eyes (23.83\u2009\u00b1\u20091.52\u2009mm). The mean anterior chamber depth in the eyes of Pacific peoples (3.20\u2009\u00b1\u20090.39\u2009mm) was significantly greater than that of Caucasians (3.09\u2009\u00b1\u20090.42\u2009mm, <jats:italic>P<\/jats:italic>\u2009=\u20090.001) and Asians (3.05\u2009\u00b1\u20090.49\u2009mm, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001).
