Cont Lens Anterior Eye. 2024 Dec;47(6):102310. doi: 10.1016/j.clae.2024.102310. Epub 2024 Sep 14.
Introduced around the turn of the 21st century, silicone hydrogel contact lenses alleviated hypoxic anterior eye complications due to their high oxygen transmissibility. The purpose of this work is to update earlier surveys by describing international trends in silicone hydrogel daily wear contact lens fitting between 2000 and 2023.
An annual contact lens prescribing survey was sent to eye care practitioners in up to 71 countries between 2000 and 2023. Data relating to 260,144 daily wear soft contact lens fits undertaken in 20 countries returning reliable longitudinal data were analysed in respect of silicone hydrogel daily wear contact lens fitting.
There has been a dramatic increase in silicone hydrogel daily wear lens fits (p < 0.0001), increasing from 2.8 % of all daily wear soft lens fits in 2000 to 73.7 % in 2023. Of all daily wear soft contact lenses prescribed to males, 44.6 % were silicone hydrogel lenses, compared with 43.5 % for females (p = 0.0146). The mean age of those wearing silicone hydrogel daily wear lenses was 32.0 ± 14.5 years, compared to 30.4 ± 13.6 years for those wearing daily wear hydrogel lenses (p < 0.0001). Between 2019-2023, the average percentage of fits was - (a) material type: silicone hydrogel - 73 %; mid-water content hydrogels - 13 %; high water content hydrogels - 9 %; and low water content hydrogels - 5 %, and (b) lens design: spherical - 44 %, toric - 32 %, multifocal - 17 %, monovision - 4 %, and 'other' - 3 %.
The dramatic increase in silicone hydrogel contact lens prescribing for daily wear has been commensurate with the introduction of multiple lens brands and an ongoing expansion of lens designs, parameters and replacement frequency options. The balance between silicone hydrogel and hydrogel lens prescribing is perhaps starting to approach an equilibrium.
硅水凝胶隐形眼镜于 21 世纪初问世，由于其高透氧性，缓解了缺氧性眼前节并发症。本研究旨在通过描述 2000 年至 2023 年期间硅水凝胶日戴隐形眼镜的国际趋势，更新之前的调查结果。
在 2000 年至 2023 年期间，我们向多达 71 个国家的眼保健从业者发送了年度隐形眼镜处方调查。对 20 个国家返回可靠纵向数据的 260144 例日戴软性隐形眼镜拟合进行了分析，这些国家的数据涉及硅水凝胶日戴隐形眼镜的拟合。
硅水凝胶日戴隐形眼镜的适配量（p<0.0001）显著增加，从 2000 年所有日戴软性隐形眼镜的 2.8%增加到 2023 年的 73.7%。在所有男性日戴软性隐形眼镜中，44.6%为硅水凝胶镜片，女性为 43.5%（p=0.0146）。佩戴硅水凝胶日戴隐形眼镜的患者平均年龄为 32.0±14.5 岁，而佩戴日戴水凝胶隐形眼镜的患者平均年龄为 30.4±13.6 岁（p<0.0001）。在 2019-2023 年期间，平均拟合百分比为 -（a）材料类型：硅水凝胶-73%；中含水量水凝胶-13%；高含水量水凝胶-9%；低含水量水凝胶-5%，和（b）镜片设计：球形-44%，散光-32%，多焦点-17%，单视-4%，和“其他”-3%。
硅水凝胶隐形眼镜的日戴处方量显著增加，这与多种镜片品牌的推出以及镜片设计、参数和更换频率选择的不断扩展是一致的。硅水凝胶和水凝胶镜片处方之间的平衡可能开始接近平衡。
