方法：将319例393眼白内障患者根据眼轴长度分为非高度近视白内障组198例237眼及高度近视白内障组121例156眼，用A型超声生物测量眼轴长度及晶状体厚度。

结果：非高度近视白内障组及高度近视白内障组在手术年龄(t=3.614，P=0.000)、晶状体厚度(t=-3.081，P=0.002)方面均有统计学差异。高度近视白内障患者手术年龄小于非高度近视白内障患者，晶状体厚度厚于非高度近视白内障患者。非高度近视白内障组手术年龄与眼轴长度无明显相关性(r=-0.081，P=0.214)，手术年龄与晶状体厚度呈正相关(r=0.178，P=0.006)，眼轴长度与晶状体厚度无明显相关性(r=-0.050，P=0.442)。高度近视白内障组手术年龄与眼轴长度呈负相关(r=-0.211，P=0.008)，手术年龄与晶状体厚度无明显相关性(r=0.078，P=0.332)，眼轴长度与晶状体厚度呈正相关(r=0.207，P=0.010)。

结论：非高度近视白内障患者随着年龄的增长，白内障逐渐加重，眼轴长度的差异未影响白内障手术年龄。高度近视白内障患者人群中，年龄的差异并未影响白内障严重程度，眼轴越长，白内障的手术年龄越小。

METHODS: A total of 319 patients(393 eyes)were divided into non-high myopia cataract group(198 patients, 237 eyes)and high myopia cataract group(121 patients, 156 eyes)according to the axial length. Axial length and lens thickness were measured with A-mode ultrasound biometry.

RESULTS: There were statistical difference in operation age(t=3.614, P=0.000), lens thickness(t=-3.081, P=0.002)between the non-high myopia cataract group and high myopia cataract group. The operation age of high myopia cataract group was younger than that of non-high myopia cataract group. The lens thickness in high myopia cataract group was thicker than that in non-high myopia cataract group. There was no significant correlation between age and axial length in the non-high myopia cataract group(r=-0.081, P=0.214). Age and lens thickness had positive correlation in the non-high myopia cataract group(r=0.178, P=0.006). Axial length and lens thickness had no significant correlation in the non-high myopia cataract group(r=-0.050, P=0.442). There was a negative correlation between age and lens thickness in the high myopia cataract group(r=-0.211, P=0.008). Age and lens thickness had no significant correlation in the high myopia cataract group(r=0.078, P=0.332). Axial length and lens thickness had positive correlation in the high myopia cataract group(r=0.207, P=0.010).

CONCLUSION: For the non-high myopia cataract patients, the cataract aggravate as the age increase. The operation age will not change as the axial length change. For the high myopia cataract patients, the cataract will not aggravate as the age increase, and the longer of the axial length, the younger of the operation age.
