Forty patients were selected to participate in a double-masked comparative study of the Seiko Plax 3 (P-3) and Varilux 2 progressive addition lenses. The study was designed to determine patient preference for either lens design. The patients wore each lens for 1 month. Following each period, a questionnaire relating to the patient's impressions of the lenses was completed. After both wearing periods, the patient's preference was determined. The results show that 89.7% of the patients preferred the Seiko lens over the Varilux. Further, 82.4% chose the Seiko lens and 44.1% chose the Varilux lens over their habitual multifocal design. The results of this study show that, in addition to a preference for the Seiko P-3 design, both progressive addition lenses are viable alternatives to the conventional multifocal lens.
四十名患者被选中参与精工Plax 3(P - 3)和万里路2渐进多焦点镜片的双盲对比研究。该研究旨在确定患者对这两种镜片设计的偏好。患者每种镜片佩戴1个月。在每个佩戴期结束后,完成一份关于患者对镜片印象的问卷。在两个佩戴期结束后,确定患者的偏好。结果显示,89.7%的患者更喜欢精工镜片而非万里路镜片。此外,与他们惯用的多焦点设计相比,82.4%的患者选择了精工镜片,44.1%的患者选择了万里路镜片。这项研究的结果表明,除了对精工P - 3设计有偏好外,这两种渐进多焦点镜片都是传统多焦点镜片的可行替代品。
