Our purpose is to evaluate the binocular contrast sensitivity function (CSF) in a presbyopic population and compare the results obtained with four different simultaneous-vision center-near multifocal contact lens (MCL) designs for distance vision under two illumination conditions. Additionally, chromatic CSF (red-green and blue-yellow) was evaluated. A randomized crossover pilot study was conducted. Four daily disposable lens designs, based on simultaneous-vision and center-near correction, were compared. The achromatic contrast sensitivity function (CSF) was measured binocularly using the CSV1000e test under two lighting conditions: room light on and off. Chromatic CSF was measured using the OptoPad-CSF test. Comparison of achromatic results with room lighting showed a statistically significant difference only for 3 cpd ( = 0.03) between the baseline visit (with spectacles) and all MCLs. Comparison of achromatic results without room lighting showed no statistically significant differences between the baseline and all MCLs for any spatial frequency ( > 0.05 in all cases). Comparison of CSF-T results showed a statistically significant difference only for 4 cpd ( = 0.002). Comparison of CSF-D results showed no statistically significant difference for all frequencies ( > 0.05 in all cases). The MCL designs analyzed provided satisfactory achromatic contrast sensitivity results for distance vision, similar to those obtained with spectacles, with no remarkable differences between designs. Chromatic contrast sensitivity for the red-green and blue-yellow mechanisms revealed some differences from the baseline that should be further investigated in future studies.
我们的目的是评估老视人群的双眼对比敏感度函数（CSF），并比较在两种照明条件下，使用四种不同的同时视近用多焦点隐形眼镜（MCL）设计进行远视力矫正时所获得的结果。此外，还评估了彩色CSF（红-绿和蓝-黄）。开展了一项随机交叉试点研究。比较了基于同时视和中心近用矫正的四种日抛型隐形眼镜设计。在两种光照条件下（室内灯开启和关闭），使用CSV1000e测试双眼测量消色差对比敏感度函数（CSF）。使用OptoPad-CSF测试测量彩色CSF。在室内照明条件下，消色差结果的比较显示，仅在3 cpd时（ = 0.03），基线访视（佩戴眼镜）与所有MCL之间存在统计学显著差异。在无室内照明条件下，消色差结果的比较显示，对于任何空间频率，基线与所有MCL之间均无统计学显著差异（所有情况下均 > 0.05）。CSF-T结果的比较显示，仅在4 cpd时存在统计学显著差异（ = 0.002）。CSF-D结果的比较显示，所有频率均无统计学显著差异（所有情况下均 > 0.05）。所分析的MCL设计为远视力提供了令人满意的消色差对比敏感度结果，类似于佩戴眼镜时获得的结果，各设计之间无显著差异。红-绿和蓝-黄机制的彩色对比敏感度显示出与基线的一些差异，应在未来研究中进一步调查。
