Purpose

To determine whether the adaption of neophytes to rigid gas permeable lenses (GPs) could be accelerated by changing their diameter or surface lubricity.

Methods

This was a 2 part prospective double-masked randomised wear study. An GP lens (Roflufocon D material, 9.6 mm diameter) with and without a Hydrapeg plasma coating surface was worn by 119 neophytes (21.1 ± 3.5 years; 77% female) on separate occasions. A further 114 neophytes (average age 20.1 ± 1.0 years; 72% female) wore the uncoated lens with a 9.6 mm diameter lens in one randomly allocated eye and 10.1 mm (n = 51) or 10.6 mm (n = 63) in the other with a basecurve compensation keeping the fit equivalent. Lens fit and corneal staining was assessed after 20 min, and comfort and bulbar redness were assessed at the time of lens application and after 5, 10, 15, and 20 min. Participants also reported their ease of application and removal on a 5 point scale.

Results

Plasma coated GP lenses or increasing diameter did not improve comfort (p = 0.673, p > 0.05) or bulbar redness (p = 0.805, p > 0.05) during a 20 min adaptation period in neophytes. In both cohorts, comfort improved and bulbar redness reduced with time (p < 0.001). Corneal staining, ease of insertion application and ease of removal did not differ with GP coating application or GP diameter (p > 0.05).

Conclusion

Changing GP diameter or surface lubricity is not beneficial to the adaption of healthy neophytes

大直径和等离子涂层对新生儿透气性隐形眼镜配件初始适应的影响。

目的

确定是否可以通过改变直径或表面润滑性来加速新手对刚性透气镜片 (GP) 的适应。

方法

这是一项由 2 部分组成的前瞻性双面罩随机佩戴研究。有和没有 Hydrapeg 等离子涂层表面的 GP 镜片（Roflufocon D 材料，直径 9.6 毫米）由 119 名新手（21.1 ± 3.5 岁；77% 女性）在不同场合佩戴。另有 114 名新手（平均年龄 20.1 ± 1.0 岁；72% 女性）佩戴无涂层镜片，其中一只随机分配的眼睛佩戴直径为 9.6 毫米的镜片，另一只眼睛佩戴直径为 10.1 毫米（n = 51）或 10.6 毫米（n = 63）的镜片使用基曲线补偿保持拟合等效。20 分钟后评估镜片贴合度和角膜染色，并在佩戴镜片时和 5、10、15 和 20 分钟后评估舒适度和球部发红情况。参与者还报告了他们在 5 分制上应用和移除的难易程度。

结果

在新手的 20 分钟适应期内，等离子涂层 GP 镜片或增加直径并没有改善舒适度（p = 0.673，p > 0.05）或球部发红（p = 0.805，p > 0.05）。在两个队列中，随着时间的推移，舒适度得到改善，球部发红减少（p < 0.001）。角膜染色、插入应用的难易度和移除的难易度与 GP 涂层应用或 GP 直径没有区别 ( p > 0.05)。

结论

改变GP直径或表面润滑性不利于健康新手的适应
