目的:刚性隐形眼镜在隐形眼镜实践中具有重要作用。这项工作的目的是通过描述2000年至2023年之间刚性镜头配件的全球趋势来更新早期调查。
方法:在2000年至2023年期间,向多达71个国家的眼部护理从业者发送了年度隐形眼镜处方调查。分析了在20个国家/地区进行的342,500个拟合数据,这些数据返回了可靠的纵向数据,定义为使用刚性材料制造的隐形眼镜的任何设计的配合。
结果:总体而言,刚性镜片处方随着时间的推移略有增加,从2000年的14.2%到2023年的15.2%(p<0.0001)。然而,事后分析显示,随时间的变化最好描述为2000年至2012年之间的下降,随后稳步上升.各国之间刚性镜片处方存在显著差异(p<0.0001)。男性佩戴刚性镜片的百分比之间的差异,占所有隐形眼镜的比例(12.7%),女性(12.0%)显著(p<0.0001),虽然没有临床意义。刚性镜片配戴者的试戴年龄比柔性镜片配戴者大(38.7岁vs31.3岁,分别)(p<0.0001)。目前(2019-2023)规定的5,994种刚性镜片配合物的分析分为:角膜球-30%;巩膜和角膜巩膜-28%;角膜近视控制/角膜塑形术-21%;和角膜复合体(包括复曲面,多焦和单视)-16%。
结论:在本世纪第二个十年中,刚性镜片的拟合度略有增加。这种增加显然是由于刚性镜片的“重新利用”,随着巩膜/角膜巩膜和近视控制/角膜塑形镜的发展,镜片适合基本上取代了传统的球面角膜镜片适合。
OBJECTIVE: Rigid contact lenses have an important role in contact lens practice. The purpose of this work is to update earlier surveys by describing global trends in rigid lens fitting between 2000-2023.
METHODS: An annual contact lens prescribing survey was sent to eye care practitioners in up to 71 countries between 2000 and 2023. Data relating to 342,500 fits undertaken in 20 countries returning reliable longitudinal data were analysed in respect of rigid lens fitting, defined as the fitting of any design of a contact lens manufactured in a rigid material.
RESULTS: Overall, rigid lens prescribing increased slightly over time, from 14.2 % of lens fits in 2000 to 15.2 % in 2023 (p < 0.0001). However, post-hoc analysis shows that the change over time is best described as a decline between 2000 and 2012, followed by a steady increase subsequently. There were significant differences in rigid lens prescribing between countries (p < 0.0001). The difference between the percentage of males fitted with rigid lenses, as a proportion of all contact lenses (12.7 %), and females (12.0 %) is significant (p < 0.0001), although not clinically meaningful. Rigid lens wearers are older at fitting than soft lens wearers (38.7 vs 31.3 years, respectively) (p < 0.0001). Analysis of 5,994 rigid lens fits prescribed currently (2019-2023) were categorised as:
corneal sphere - 30 %; scleral and corneo-scleral - 28 %;
corneal myopia control/orthokeratology - 21 %; and
corneal complex (including toric, multifocal and monovision) - 16 %.
CONCLUSIONS: There has been a slight increase in rigid lens fitting during the second decade of this century. This increase is apparently due to a \'repurposing\' of rigid lenses, with the growth of scleral/corneo-scleral and myopia control/orthokeratology lens fits essentially replacing conventional spherical
corneal lens fits.
