目的：比较WaveScan和OPD-Scan Ⅲ像差仪在测量屈光不正度数方面与主觉验光结果之间的差异。 　　方法：选取2013-01/12来我院激光治疗中心进行近视矫正的患者76例152眼,所有患者先后采用综合验光仪( NIDEK, RT-5100)进行主觉验光, WaveScan ( AMO Company, USA )和 OPD - Scan Ⅲ像差仪( Nidek Technologies,Japan)进行客观验光检查。对这三种方法验光结果的球镜、柱镜及轴位进行统计学分析与比较。 　　结果：WaveScan验光的球镜度数较主觉验光结果偏低,差值0.13±0.30D (t=3.753, P<0.001),柱镜结果偏高0.13±0.43D(t=3.664, P<0.001)。 OPD-Scan Ⅲ与主觉验光球镜、柱镜及等效球镜之间的差异均无统计学意义( P>0.05)。 WaveScan 与主觉验光轴位度数平均相差5.87o±6.19o,OPD-ScanⅢ与主觉验光平均相差3.82o±3.95o,两者之间的差异有统计学意义( t=2.817, P=0.006)。 　　结论：WaveScan与主觉验光球镜及柱镜结果之间有差异, OPD-Scan Ⅲ作为最新的综合设备,在验光度数上有较高的准确性。

AIM:To compare the refractive errors measured by the VISX WaveScan, OPD - Scan Ⅲ and the subjective refraction. METHODS: Seventy - six patients ( 152 eyes ) were recruited from January 2013 to December 2013. All patients were measured with subjective refraction by the phoropter (NIDEK, RT-5100), objective refraction by the WaveScan ( AMO Company, USA) , OPD-ScanⅢ ( Nidek Technologies, Japan). The sphere, cylinder, axis of the three methods were compared and analyzed. RESULTS: The sphere measured by WaveScan was lower than that by subjective refraction, the difference was 0. 13±0. 30D (t=3. 753, P<0. 001). For cylinder, the difference was 0. 13±0. 43D (t=3. 664, P<0. 001). There was no significance for sphere, cylinder, and spherical equivalent between OPD - Scan Ⅲ and subjective refraction (P>0. 05). The value of the difference between WaveScan and subjective refraction was 5. 87o±6. 19o for the axis and the difference between OPD-Scan Ⅲ and subjective refraction was 3. 82o±3. 95o. There was statistic significance (t=2. 817, P=0. 006). CONCLUSION: For sphere and cylinder, WaveScan generated some deviation relative to subjective refraction. The Nidek OPD-ScanⅢ gives more accurate measures of objective refraction when compared with subjective refraction.
