摘要
目的:比较WaveScan和OPD-ScanⅢ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-5 100)进行主觉验光,WaveScan(AMO Company,USA)和OPD-ScanⅢ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-ScanⅢ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5.87°±6.19°,OPD-ScanⅢ与主觉验光平均相差3.82°±3.95°,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-ScanⅢ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.
