Abstract

Abstract This study investigated the characteristics and location of the pigment layer of commercially available tinted contact lenses and evaluated ocular surface properties. The rub-off test and anterior segment Fourier-domain optical coherence tomography were used to analyze the pigment layer of the lenses. They also completed a rating questionnaire of subjective symptom perception after wearing. Among the four groups, there were significant differences in the ocular surface properties on day 3 (p < 0.05). Most of the ocular surface properties were significantly different between baseline and after being worn on day 1, day 3 and day 7 (p < 0.05), especially for tinted contact lenses with pigment layers on the lens surface. On initial wearing of the tinted contact lenses, contact between pigment layers on the surface of the lens and ocular tissues appeared to irritate the ocular surface more than non-pigment layers on the surface. Pigment-tinted soft contact lenses with lower oxygen permeability may cause worse ischemic signs on the ocular surface. However, the ocular surface adapted gradually and the symptoms decreased after wearing the tinted contact lens.

不同特征及色素位置的有色软性隐形眼镜眼表反应评价

摘要本研究调查了商用有色隐形眼镜色素层的特性和位置，并评估了眼表性能。采用摩擦试验和前段傅立叶域光学相干断层扫描对晶状体色素层进行分析。他们还完成了一份关于佩戴后主观症状感知的评分问卷。在四组中，第3天的眼表特性有显著差异（p < 0.05）。在基线和佩戴后的第1天、第3天和第7天，大多数眼表特性有显著差异（p < 0.05），特别是对于在镜片表面上具有颜料层的有色隐形眼镜。在初次佩戴有色隐形眼镜时，镜片表面的色素层和眼组织之间的接触似乎比表面的非色素层更刺激眼表面。氧气渗透性较低的色素色软性隐形眼镜可能会导致眼表缺血性症状恶化。然而，佩戴有色隐形眼镜后，眼表逐渐适应，症状减轻。
