To quantitatively assess visual performance and patient satisfaction during photochromic contact lens (CL) wear in an indoor environment.
This observational study comprised 82 eyes of 41 healthy subjects (mean age ± standard deviation, 21.7 ± 0.7 years) who had no ophthalmic diseases except for refractive errors at Kitasato University in 2021. We prospectively compared visual acuity, kinetic visual acuity, functional (time-dependent) visual acuity, the maintaining rate of visual acuity, the response time, contrast sensitivity function, higher-order aberrations, and patient satisfaction score for overall vision in such subjects during photochromic and non-photochromic CL wear in such an environment.
The kinetic visual acuity at 30 km/h was 0.32 ± 0.21 and 0.41 ± 0.24 in the photochromic and non-photochromic CL groups, respectively (p = 0.008). The kinetic visual acuity at 60 km/h was 0.32 ± 0.21 and 0.41 ± 0.24, respectively (p = 0.034). The functional visual acuity was 0.00 ± 0.21 and 0.05 ± 0.25, respectively (p = 0.030). The average response time was 1.19 ± 0.15 s and 1.23 ± 0.15 s, respectively (p = 0.029). The patient satisfaction score for overall visual performance was 4.22 ± 0.11 and 3.59 ± 0.68, respectively (p < 0.001). Otherwise, we found no significant differences in visual acuity, the maintaining rate, higher-order aberrations, or contrast sensitivity function (p = 0.116, p = 0.053, p = 0.371, or p = 0.943). We found no apparent complications such as ocular discomfort, superficial punctate keratitis, conjunctival injection, or infectious keratitis during the observation period.
According to our experience, the photochromic CL showed good visual quality, especially in terms of kinetic and functional visual acuities and subsequent high patient satisfaction, even in an indoor environment, suggesting its viability of visual correction not only in daily activities but also in indoor sports activities.
定量评估室内环境中光致变色隐形眼镜（CL）佩戴期间的视觉性能和患者满意度。
这项观察性研究纳入了2021年在北里大学的41名健康受试者（平均年龄±标准差，21.7±0.7岁）的82只眼睛，这些受试者除屈光不正外无眼部疾病。我们前瞻性地比较了这些受试者在光致变色和非光致变色CL佩戴期间的视力、动态视力、功能性（时间依赖性）视力、视力维持率、反应时间、对比敏感度函数、高阶像差以及总体视觉的患者满意度得分。
光致变色CL组和非光致变色CL组在30km/h时的动态视力分别为0.32±0.21和0.41±0.24（p = 0.008）。在60km/h时的动态视力分别为0.32±0.21和0.41±0.24（p = 0.034）。功能性视力分别为0.00±0.21和0.05±0.25（p = 0.030）。平均反应时间分别为1.19±0.15秒和1.23±0.15秒（p = 0.029）。总体视觉性能的患者满意度得分分别为4.22±0.11和3.59±0.68（p < 0.001）。否则，我们发现视力、维持率、高阶像差或对比敏感度函数方面无显著差异（p = 0.116、p = 0.053、p = 0.371或p = 0.943）。在观察期内未发现明显并发症，如眼部不适、浅层点状角膜炎、结膜充血或感染性角膜炎。
根据我们的经验，光致变色CL显示出良好的视觉质量，尤其是在动态和功能性视力方面，以及随后较高的患者满意度，即使在室内环境中也是如此，这表明其不仅在日常活动中，而且在室内体育活动中进行视力矫正的可行性。
