摘　　要：目的评价Zywave波前像差仪在近视屈光不正测量中的临床应用价值。方法选择2010年8月至2011年2月在本院拟行近视屈光不正矫正术的患者197例(394眼),根据患者在睫状肌麻痹前电脑验光的球镜度数分成一般度数组(<-6.00D)、高度数组(-6.00～-9.00D)和超高度数组(>-9.00D)3组。对同一眼的球镜度数、散光度数和散光轴向分别用电脑验光仪、Zywave波前像差仪和综合验光仪三种检查方法测量,所得结果行统计学分析。结果一般度数组:电脑验光、Zywave波前像差仪、综合验光仪3种方法测得的球镜度数分别为(-4.05±1.41)D、(-3.90±1.44)D、(-4.06±1.33)D,散光度数分别为(-1.74±0.88)D、(-1.59±0.71)D、(-1.53±0.69)D,散光轴向分别为(85.98±43.88)°、(99.18±45.21)°、(94.02±45.98)°,3种方法测量结果之间比较,差异均无统计学意义(均为P>0.05)。高度数组:电脑验光、Zywave波前像差仪和综合验光仪3种方法测得的球镜度数分别为(-7.51±0.83)D、(-7.80±0.76)D、(-7.54±0.79)D,散光度数分别为(-1.64±1.17)D、(-1.92±1.01)D、(-1.74±1.00)D,散光轴向分别为(79.90±43.15)°、(96.07±50.56)°、(81.31±46.98)°,3种方法测量结果之间比较,差异均无统计学意义(均为P>0.05)。超高度数组:电脑验光、Zywave波前像差仪、综合验光仪3种方法测得的球镜度数分别为(-12.01±1.81)D、(-11.78±1.81)D、(-12.60±1.78)D,散光度数分别为(-1.56±0.88)D、(-1.85±1.01)D、(-2.16±0.80)D,散光轴向分别为(93.80±34.23)°、(106.70±35.55)°、(95.20±29.47)°,3种方法测量结果之间比较,球镜度数及散光轴向差异均无统计学意义(均为P>0.05),而散光度数间差异有统计学意义(P<0.05)。结论 Zywave波前像差仪测量近视屈光不正有较高的准确性,在临床应用中有一定的参考价值。Objective To evaluate the value of Zywave wavefront analyzer in measurement of myopic ametropia. Methods One hundred and ninety-seven patients （394 eyes） with myopic ametropia in our hospital from August 2010 to February 2011 were divided into 3 groups based on the spherical degree before cycloplegia by comput- er optometry： General myopia group （ 〈 - 6.00 D）, high myopia group （ from - 6.00 D to - 9.00 D） and hypermyopia group （ 〉 - 9.00 D）. The spherical degree, astigmatism degree and axis in the same eye were measured by computer optometry,Zywave wave- front analyzer, integrated refractometer, the results were statistical analyzed. Results In general myopia group, the spherical degrees measured by computer optometry, Zy- wave wavefront analyzer,integrated refractometer were （ - 4.05 ± 1.41 ） D, （ - 3.9± 1.44） D and （ - 4.06± 1.33 ） D, astigmatism degrees were （ - 1.7±0.88 ） D, （ - 1.59±0.71）D and （ - 1.53 ±0.69） D,and the axis of astigmatism were （85.98 ±43.88）°, （99.18±45.21 ）° and （94.02 ± 45.98 ）°~ ,there was no statistical difference among three methods （ all P 〉 0.05 ）. In high myopia group, the spherical degrees measured by com- puter optometry, Zywave wavefront analyzer, integrated refractometer were （ - 7.51 ± 0.83 ） D, （ - 7.80 ± 0.76） D and （ - 7.54± 0.79） D, astigmatism degrees were （ - 1.64 ± 1.17）D,（ -1.92 ±1.01）D and （ -1.74 ± 1.00）D,and the axis of astigmatism were （79.90 ±43. 15）°, （96.07 ＋50.56）° and （81.31±46.98）°,there was no statistical difference among three methods （ all P 〉 0.05 ）. In hypermyopia group, the spherical degrees measured by computer optometry, Zywave wavefront analyzer, integrated refrac- tometer were （ - 12.01 ± 1.81 ） D, （ - 11.78 ± 1.81 ） D and （ - 12.60± 1.78 ） D, astigma- tism degrees were （ - 1.56 ± 0.88） D, （ - 1.85 ± 1.01 ） D and （ - 2.16 ± 0.80） D, and the axis of astigmatism were （93.80 ± 34.23 ）°, �
