Silicone hydrogel contact lenses were introduced into the market in 1999. To assess prescribing trends of this lens type since then, up to 1000 survey forms were sent to contact lens fitters in Australia, Canada, Japan, the Netherlands, Norway, the UK and the USA each year between 2000 and 2008. Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the survey form. Analysis of returned forms revealed a rapid increase in the prescribing of silicone hydrogel lenses over the survey period. In 2008, silicone hydrogel lenses represented 36% of all soft lenses prescribed. The categorization of the majority of lenses prescribed as 'refits' is primarily attributed to the mass conversion of lens wearers from hydrogel to silicone hydrogel lenses. Silicone hydrogels may soon represent the majority of soft contact lenses prescribed.
硅水凝胶隐形眼镜于 1999 年投放市场。为了评估自那时以来这种镜片类型的开方趋势，2000 年至 2008 年间，每年向澳大利亚、加拿大、日本、荷兰、挪威、英国和美国的隐形眼镜配镜师发送了多达 1000 份调查问卷。从业者被要求记录在收到调查问卷后进行的前 10 次隐形眼镜适配或重新适配的数据。对返回表格的分析显示，在调查期间，硅水凝胶镜片的开方量迅速增加。2008 年，硅水凝胶镜片占所有软性镜片开方量的 36%。大多数镜片被归类为“重新适配”，这主要归因于隐形眼镜佩戴者从水凝胶向硅水凝胶镜片的大规模转换。硅水凝胶可能很快就会成为软性隐形眼镜的主要开方类型。
