The primary goal of this study was to evaluate if there is a difference in frequency and in completeness of eyeblinks (type of eyeblink) in rigid gas permeable (GP) lens wearers experiencing 3- and 9-o'clock staining compared with GP lens wearers without substantial staining and nonlens wearers.
The study involved 26 nonlens wearers and 55 GP contact lens wearers, with and without 3- and 9-o'clock staining. Every eyeblink over a 5-min period was categorized as a complete eyeblink, incomplete eyeblink, or an eyeblink attempt. In addition, type of lens fit (interpalpebral vs. lid attachment), lens-to-cornea fit (flat vs. steep), spherical equivalent of the refraction, and corneal coverage (on-eye lens diameter) were analyzed.
No difference in overall eyeblink frequency was found between nonlens wearers (group I, n = 26), GP lens wearers with less than grade 1 corneal staining (group II, n = 25) and GP lens wearers with grade 1 or more corneal staining (group III, n = 30). Fewer complete eyeblinks, more incomplete eyeblinks and more eyeblink attempts were seen in group III than in group I or II (p < 0.01, p = 0.03, p < 0.01, respectively). Fewer complete eyeblinks and more eyeblink attempts (p < 0.01 for both) were found in interpalpebral lens fits than in lid attachment fits. Fewer complete eyeblinks (p = 0.02) and more incomplete eyeblinks (p = 0.03) were found with lenses rated as large or optimal in size than with lenses rated as small.
GP lens wearers experiencing 3- and 9-o'clock staining showed a different eyeblink frequency for individual types of eyeblinks, but not for overall eyeblinks. Fewer complete eyeblinks, more incomplete eyeblinks, and more eyeblink attempts were observed in GP wearers with 3- and 9-o'clock staining compared with wearers with minimal staining and nonwearers. In addition, some individual contact lens variables were associated with more incomplete eyeblinks.
本研究的主要目的是评估与无明显染色的硬性透气性（GP）隐形眼镜佩戴者及非隐形眼镜佩戴者相比，出现3点和9点染色的GP隐形眼镜佩戴者的眨眼频率和眨眼完整性（眨眼类型）是否存在差异。
该研究纳入了26名非隐形眼镜佩戴者以及55名有或无3点和9点染色的GP隐形眼镜佩戴者。在5分钟内的每次眨眼被分类为完整眨眼、不完整眨眼或眨眼尝试。此外，还分析了镜片适配类型（睑裂间适配与眼睑附着适配）、镜片与角膜的适配情况（平坦与陡峭）、等效球镜度以及角膜覆盖范围（眼上镜片直径）。
在非隐形眼镜佩戴者（I组，n = 26）、角膜染色小于1级的GP隐形眼镜佩戴者（II组，n = 25）和角膜染色为1级或更高的GP隐形眼镜佩戴者（III组，n = 30）之间，总体眨眼频率未发现差异。与I组或II组相比，III组的完整眨眼次数更少，不完整眨眼次数更多，眨眼尝试次数更多（分别为p < 0.01、p = 0.03、p < 0.01）。睑裂间镜片适配的完整眨眼次数少于眼睑附着适配，眨眼尝试次数更多（两者均为p < 0.01）。尺寸评定为大或最佳的镜片相比尺寸评定为小的镜片，完整眨眼次数更少（p = 0.02），不完整眨眼次数更多（p = 0.03）。
出现3点和9点染色的GP隐形眼镜佩戴者在不同类型眨眼的频率上表现出差异，但总体眨眼频率无差异。与染色轻微的佩戴者和非佩戴者相比，出现3点和9点染色的GP隐形眼镜佩戴者的完整眨眼次数更少，不完整眨眼次数更多，眨眼尝试次数更多。此外，一些个体隐形眼镜变量与更多的不完整眨眼有关。
