To review contact lens prescribing trends in Japan between 2003 and 2016.
An annual survey of contact lens prescribing trends was conducted each year between 2003 and 2016. Japanese ophthalmologists were asked to provide information relating to ten consecutive contact lens fittings between January and March every year.
Over the 14 years of the annual survey, data from a total of 64,122 contact lens fits were returned by ophthalmologists. The mean age (±SD) of lens wearers was 30 ± 13 years, and 68% were female. The proportion of rigid lens fits decreased over time, from 35.4% in 2003 to 14.7% in 2016. Across this period, daily disposable lens fits increased, representing 46% in 2016. The proportion of toric lenses and multifocal lenses gradually increased, from 6.6% and 1.9% to 12.3% and 5.8%, respectively. Silicone hydrogel material use grew from 0% to 43.2%, while mid and low water content lens materials declined from 54.1% and 28.2% to 36.1% and 8.3%, respectively. Multi-purpose lens care solutions dominated the market over the 14 year survey period.
This survey has revealed prescribing trends and preferences in Japan over the past 14 years, with the main changes observed being a decrease in rigid lens use and an increase in the use of silicone hydrogel materials and daily disposable lenses.
回顾2003年至2016年日本的隐形眼镜处方趋势。
在2003年至2016年期间，每年进行一次隐形眼镜处方趋势年度调查。要求日本眼科医生提供每年1月至3月期间连续十次隐形眼镜验配的相关信息。
在为期14年的年度调查中，眼科医生共返回了64122例隐形眼镜验配数据。隐形眼镜佩戴者的平均年龄（±标准差）为30±13岁，其中68%为女性。硬性镜片验配的比例随时间下降，从2003年的35.4%降至2016年的14.7%。在此期间，日抛型镜片验配量增加，2016年占46%。散光镜片和多焦点镜片的比例逐渐上升，分别从6.6%和1.9%升至12.3%和5.8%。硅水凝胶材料的使用从0%增至43.2%，而中、低含水量镜片材料则分别从54.1%和28.2%降至36.1%和8.3%。在为期14年的调查期内，多功能镜片护理液主导市场。
本次调查揭示了日本过去14年的处方趋势和偏好，观察到的主要变化是硬性镜片使用减少，硅水凝胶材料和日抛型镜片的使用增加。
