Purpose

Investigate changes in optical properties of contact lenses materials (transmittance and reflectance) and lens care solutions (absorption and fluorescence) resulting from its interaction.

Methods

From an experimental study, triplicate measurements of transmittance and reflectance of five contact lenses (Senofilcon A, Lotrafilcon B, Balafilcon A, Comfilcon A, and Omafilcon A), as well as UV-vis absorption and fluorescence of four lens care solutions (LCS) (ReNu MultiPlus, Biotrue, OPTI-FREE PureMoist, and AOSept Plus), were evaluated before and after 8 h, one day and one week in storage. The outcomes were provided by Shimadzu UV3101-PC UV–vis-NIR spectrophotometer equipped with an integrating sphere, between 200−700 nm, and SPEX-Fluorolog 2 FL3-22 spectrofluorometer.

Results

All variables exhibited statistically significant differences over time. Comfilcon A showed the lowest ultraviolet radiation (UVR) A & B attenuation. Balafilcon A and Lotrafilcon B displayed a slight suppression of UVR. Senofilcon A was effective in UVR protection and showed less effect on the fluorescence of lens care solutions. Overall, the reflectance decreased after storage (p < 0.05). AOSept Plus absorbance and fluorescence demonstrated lower interactions than multipurpose solutions (MPS), and Lotrafilcon B induced more remarkable changes in optical properties of LCS than the other materials.

Conclusion

The findings suggest that optical variables of lens care solutions and contact lenses changed mutually after storage, probably associated with biochemical and biophysical interactions between components and the release of some polymer compounds. These findings can provide additional information about the interaction of CL materials and LCS in clinical behavior.

隐形眼镜和镜片护理液之间的相互作用：对光学特性的影响

目的

研究隐形眼镜材料（透射率和反射率）和镜片护理液（吸收和荧光）的光学特性因相互作用而发生的变化。

方法

在一项实验研究中，对五种隐形眼镜（Senofilcon A、Lotrafilcon B、Balafilcon A、Comfilcon A 和 Omafilcon A）的透射率和反射率进行三次测量，以及四种镜片护理液 (LCS) 的紫外-可见吸收和荧光（ReNu MultiPlus、Biotrue、OPTI-FREE PureMoist 和 AOSept Plus）在储存 8 小时、1 天和 1 周之前和之后进行评估。结果由配备积分球的 Shimadzu UV3101-PC UV-vis-NIR 分光光度计和 SPEX-Fluorolog 2 FL3-22 分光光度计提供，在 200-700 nm 之间。

结果

随着时间的推移，所有变量都表现出统计学上的显着差异。Comfilcon A 显示出最低的紫外线辐射 (UVR) A 和 B 衰减。Balafilcon A 和 Lotrafilcon B 显示出对 UVR 的轻微抑制。Senofilcon A 对 UVR 保护有效，对镜片护理液的荧光影响较小。总体而言，储存后反射率下降（p < 0.05）。AOSept Plus 吸光度和荧光显示出比多用途溶液 (MPS) 更低的相互作用，并且与其他材料相比，Lotrafilcon B 在 LCS 的光学特性方面引起了更显着的变化。

结论

研究结果表明，镜片护理液和隐形眼镜的光学变量在储存后相互变化，可能与成分之间的生化和生物物理相互作用以及某些高分子化合物的释放有关。这些发现可以提供关于 CL 材料和 LCS 在临床行为中相互作用的额外信息。
