自动电脑验光仪与伟仑双目视力筛查仪在近视筛查中的应用效果比较

Comparison of the Application Effect of Automatic Computer Optometry and Weilun Binocular Vision Screening Instrument in Myopia Screening

目的:探究自动电脑验光仪与伟仑双目视力筛查仪在近视筛查中的应用效果。方法:选取2021年6月~2022年9月本院门诊进行近视筛查纳入的80例疑似近视者(160只眼睛)为研究对象,患者分别接受自动电脑验光仪、伟仑双目视力筛查仪检查,并在散瞳后再次进行上述检查,以散瞳后的检影验光检查为对照组,以自动电脑验光仪的检测结果为研究组1,以伟仑双目视力筛查仪的检测结果为研究组2。评估两种方法的近视检出率及其在自然瞳孔下的验光情况与散瞳后的剪影验光情况。结果:三组近视检出人数无明显差异(P>0.05);散瞳后研究组1与对照组测得的柱镜值、轴向无明显差异(P>0.05),球镜值存在显著差异;研究组1散瞳后与散瞳前测得的柱镜值、轴向无明显差异(P>0.05),球镜值有明显差异(P<0.05);散瞳后研究组2与对照组测得的球镜值、柱镜值、轴向均无明显差异(P>0.05);研究组2散瞳后与散瞳前测得的轴向及柱镜值均无明显差异(P>0.05),球镜值有明显差异但相较于研究组1差异更小(P<0.05)。结论:自动电脑验光仪、伟伦双目视力筛查仪筛查结果均能为临床筛查近视提供有效依据,但伟伦双目视力筛查仪的结果更为准确。

Objective:To explore the application effect of automatic autorefrintor and Weilun binocular vision screening instrument in myopia screening.Methods:From June 2021 to September 2022,80 patients(160 eyes)with suspected myopia were selected for myopia screening in the outpatient department of our hospital as the research object.The patients were examined by automatic autorefrintor and Weilu binocular vision screening instrument,and the above examinations were performed again after mydriasis.The test results of automatic autorefrintor were used as study group 1,and the test results of Weilu binocular vision screener were used as study group 2.The detection rate of myopia and its refraction under natural pupil and silhouette refraction after mydriasis were evaluated.Results:There was no significant difference in the number of myopia among the three groups(P>0.05).After mydriasis,there was no significant difference in cylinder value and axis between the study group 1 and the control group(P>0.05),but there was a significant difference in spherical value.In study group 1,there was no significant difference in cylinder and axis between before and after mydriasis(P>0.05),but there was significant difference in spherical refraction(P<0.05).After mydriasis,there was no significant difference in spherical,cylindrical and axial values between the study group 2 and the control group(P>0.05).There was no significant difference in the axial and cylindrical refraction values between the two groups(P>0.05),but the spherical refraction values in the study group 2 were significantly different than those in the study group 1(P<0.05).Conclusion:The results of automatic autorefrintor and Weilun binocular vision screening instrument can provide effective evidence for clinical myopia screening,but the results of Weilun binocular vision screening instrument are more accurate.
