Abstract：
OBJECTIVE: Extended wear has long been considered as the ultimate contact lens modality in terms of user convenience. The purpose of this work is to update earlier surveys by describing international trends in extended wear soft lens fitting between 2000 and 2023, inclusive.
METHODS: 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 282,142 soft contact lens fits undertaken in 20 countries returning reliable longitudinal data were analysed in respect of extended wear soft lens fitting.
RESULTS: Over the duration of the work there was a very small decrease in the prescribing of extended wear soft lenses (p < 0.0001). More detailed inspection shows that prescribing of these lenses steadily increased from 5.8 % of all soft lens fits in 2000 to 11.6 % in 2007, then steadily decreased to 5.2 % in 2023. Of all soft contact lenses prescribed to males, 9.2 % were fitted for extended wear, compared with 6.7 % for females (p < 0.0001). The mean age of extended wear soft lens wearers at fitting was 34.7 ± 14.7 years, compared to 31.1. ± 14.10 years for daily soft lens wearers (p < 0.0001). Analysis of 1,948 recent extended wear soft lens fits (2019-2023, inclusive), in terms of material type, revealed that, on average, 86 % and 14 % of extended wear soft lenses were fitted using silicone hydrogel and hydrogel materials, respectively.
CONCLUSIONS: A modest increase in extended wear soft lens prescribing from 2000 to 2007 corresponded with the introduction of high oxygen transmissibility silicone hydrogel lenses. However, prescribing of this lens type declined thereafter, probably due to ongoing concerns over their increased rate of microbial keratitis, resulting in a prescribing rate in 2023 (5.2%) that was little different to that observed in 2000 (5.8%).

摘要：
目的：就用户便利性而言，延长佩戴一直被认为是最终的隐形眼镜方式。这项工作的目的是通过描述2000年至2023年之间的长期佩戴软镜片配件的国际趋势来更新早期的调查。
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282,142个软性隐形眼镜配镜的数据，这些数据返回了可靠的纵向数据，以进行长期配戴软性眼镜配镜。
结果：在整个工作过程中，长期佩戴软性镜片的处方量下降很小（p<0.0001）。更详细的检查表明，这些镜片的处方从2000年所有软性镜片的5.8％稳步增加到2007年的11.6％，然后在2023年稳步下降到5.2％。在所有男性处方的软性隐形眼镜中，9.2%适合长期磨损，女性为6.7%(p<0.0001)。长期佩戴软镜配戴者的平均年龄为34.7±14.7岁，与31.1相比。每日软镜佩戴者±14.10年(p<0.0001)。最近1,948个延长佩戴软镜合装（含2019-2023年）的分析，就材料类型而言，透露，平均而言,86％和14％的长期佩戴软镜使用硅水凝胶和水凝胶材料，分别。
结论:从2000年至2007年处方的延长佩戴软性镜片的适度增加与高透氧性硅酮水凝胶镜片的引入相对应。然而,此后，这种镜片类型的处方下降了，可能是由于对微生物角膜炎发病率增加的持续担忧，导致2023年的处方率（5.2％）与2000年的处方率（5.8％）几乎没有差异。
