There have been significant advancements in toric soft contact lens design and manufacturing technology, and increased product availability, over the past half a century. The purpose of this work is to update earlier surveys by describing international trends in toric soft lens fitting between 2000 and 2023, inclusive.
An annual contact lens prescribing survey was sent to eye care practitioners in up to 71 countries between 2000 and 2023, inclusive. Data relating to 220,934 standard soft daily wear single vision lens fits undertaken in 20 countries returning reliable longitudinal data were analysed in respect of toric soft lens fitting.
Overall, toric soft lens prescribing almost doubled over the time-course of this survey, from 24.4 % of standard soft daily wear single vision lens fits in 2000 to 46.2 % in 2023 (p < 0.0001). There were significant differences between countries in toric soft lens prescribing (p < 0.0001). Of all standard soft daily wear single vision contact lenses prescribed to males, 32.0 % were toric soft lenses, compared with 28.7 % for females (p < 0.0001). The mean age of toric soft lens wearers was 30.5 ± 12.5 years, compared to 27.9. ± 12.1 years for spherical soft lens wearers (p < 0.0001). Analysis of 13,582 recent toric soft lens fits (2019-2023, inclusive), in terms of material type and replacement frequency, revealed the following proportions: reusable silicone hydrogel - 51 %; daily disposable silicone hydrogel - 27 %; daily disposable hydrogel - 12 %; and reusable hydrogel - 10 %.
There has been a substantial increase in toric soft lens fitting throughout the 24 years of this survey, to a point whereby almost all clinically significant astigmatism is being corrected among those wearing standard soft daily wear single vision lenses.
在过去的半个世纪里，散光软镜设计和制造技术取得了重大进展，产品供应也有所增加。本研究旨在更新以往的研究，描述 2000 年至 2023 年期间全球范围内散光软镜的适配趋势。
在 2000 年至 2023 年期间，向 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 个国家返回的 220934 例有可靠纵向数据的标准软日戴单视隐形眼镜适配情况进行了分析，这些国家共进行了 220934 例标准软日戴单视隐形眼镜适配，涉及散光软镜适配。
总体而言，在这项研究期间，散光软镜的处方量几乎翻了一番，从 2000 年的标准软日戴单视隐形眼镜适配的 24.4%增加到 2023 年的 46.2%（p<0.0001）。各国在散光软镜处方方面存在显著差异（p<0.0001）。在所有男性标准软日戴单视隐形眼镜中，32.0%为散光软镜，而女性为 28.7%（p<0.0001）。散光软镜佩戴者的平均年龄为 30.5±12.5 岁，而球形软镜佩戴者为 27.9±12.1 岁（p<0.0001）。对 2019 年至 2023 年（共 13582 例）最近的散光软镜适配进行分析，根据材料类型和更换频率，发现以下比例：可重复使用硅水凝胶-51%；日抛硅水凝胶-27%；日抛水凝胶-12%；和可重复使用水凝胶-10%。
在这项研究的 24 年期间，散光软镜的适配量大幅增加，几乎所有需要矫正的临床显著散光都在佩戴标准软日戴单视隐形眼镜的人群中得到了矫正。
