We prospectively evaluated the NOVAWET-Perception multifocal contact lens for comfort and performance.
We fit 28 presbyopic patients with this multifocal contact lens. This multifocal rigid gas permeable lens has a multiaspheric back surface and multiple eccentricity values, allowing for a natural field of vision at all angles. Patients were evaluated prior to inclusion in the study and then at 1,3, and 9 months. Evaluations included slit lamp examination, visual acuity, contrast sensitivity, and completion of a questionnaire regarding comfort and overall satisfaction.
At the end of the study, 14 of 28 patients (50%) were successfully wearing the NOVAWET-Perception lenses. Of these, 12 (86%) achieved J2 or better near vision and 13 (93%) achieved 20/25 or better distance vision. Fourteen patients failed to complete the study.
We believe the NOVALENS multifocal contact lens is a viable option for the correction of many presbyopic patients.
我们前瞻性地评估了NOVAWET-Perception多焦点隐形眼镜的舒适度和性能。
我们为28名老花眼患者验配了这种多焦点隐形眼镜。这种多焦点硬性透气性隐形眼镜具有多球面后表面和多个偏心率值，可在各个角度提供自然视野。在纳入研究之前以及之后的1、3和9个月对患者进行评估。评估内容包括裂隙灯检查、视力、对比敏感度以及完成一份关于舒适度和总体满意度的问卷。
在研究结束时，28名患者中有14名（50%）成功佩戴了NOVAWET-Perception镜片。其中，12名（86%）患者近视力达到J2或更好，13名（93%）患者远视力达到20/25或更好。14名患者未能完成研究。
我们认为NOVALENS多焦点隐形眼镜是矫正许多老花眼患者的一个可行选择。
