客观视觉质量分析系统测量人工晶体伪调节力的临床研究

Comparison of pseudoaccommodation measured by optical quality analysis system

目的运用双通道视觉质量分析系统(OQAS)测量白内障患者人工晶体植入术后的伪调节力,并与传统的主观检测手段进行对比,比较三种方法的差异性和一致性。方法于济南第二人民医院眼科门诊随机选择30例(30眼)年龄相关性白内障患者,手术植入同类型两袢单焦点非球面人工晶体,术后1个月用OQAS检查、离焦法、推进法测量每位白内障患者人工晶体植入术后的伪调节力。结果 OQAS检查、离焦法、推进法测得的人工晶体伪调节力平均值分别为2.34D、2.5D和2.93D;OQAS检查与离焦法差异无统计学意义,OQAS检查与推进法的测量值差异有统计学意义(P<0.05)。结论 OQAS检查测量的伪调节力相对较小,其测量结果与离焦法所测结果数值相近。

Objective To study pseudoaccommodation of different intraocular lenses with a double-pass system,and the results were compared with those by the defocus method and push-up method.Methods A total of 30 outpatients with age-related cataract were selected in this study.All the enrolled eyes were implanted with the same aspheric in-traocular lens.The pseudoaccommodation of each selected eye was measured by optical quality analysis system （OQAS）,defocus system and push-up method one month after the operation.Results The average pseudoaccommoda-tion by OQAS examination,defocus method and push-up method was 2.34D,2.5D and 2.93D,respectively.There’s no statistical difference between OQAS examination and defocus method（P〉0.05）.But there’s statistical difference between OQAS examination and push-up method（P 〈0.05）.Conclusion The pseudoaccommodation measured by OQAS was relatively small.The results measured by OQAS was in close agreement with that measured by defocus method.
