To characterize toric contact lens prescribing worldwide.
Up to 1,000 survey forms were sent to contact lens fitters in up to 39 countries between January and March every year for 5 consecutive years (2007-2011). Practitioners were asked to record data relating to the first 10 contact lens fits or refits performed after receiving the survey form. Only data for toric and spherical soft lens fits were analyzed. Survey data collected since 1996 were also analyzed for 7 nations to assess toric lens fitting trends since that time.
Data were collected in relation to 21,150 toric fits (25%) and 62,150 spherical fits (75%). Toric prescribing ranged from 6% of lenses in Russia to 48% in Portugal. Compared with spherical fittings, toric fittings can be characterized as follows: older age (29.8 ± 11.4 years vs. 27.6 ± 10.8 years for spherical lenses); men are overrepresented (38% vs. 34%); greater proportion of new fits (39% vs. 32%); use of silicone hydrogel lenses (49% vs. 39%); and lower proportion of daily disposable lenses (14% vs. 28%). There has been a continuous increase in toric lens prescribing between 1996 and 2011. The proportion of toric lens fits was positively related to the gross domestic product at purchasing power parity per capita for year 2011 (r = 0.21; P=0.004).
At the present time, in the majority of countries surveyed, toric soft contact lens prescribing falls short of that required to correct clinically significant astigmatism (≥ 0.75 diopters) in all lens wearers.
描述全球散光软性角膜接触镜的处方情况。
在每年的 1 月至 3 月间，连续 5 年（2007-2011 年）向 39 个国家/地区的接触镜验配师发放了多达 1000 份调查问卷。要求从业者记录在收到调查问卷后进行的前 10 例软性角膜接触镜适配或更换的相关数据。仅对散光和球性软性角膜接触镜的适配数据进行分析。还分析了自 1996 年以来收集的调查数据，以评估自那时以来散光软性角膜接触镜的适配趋势。
共收集到 21150 例散光软性角膜接触镜适配（25%）和 62150 例球性软性角膜接触镜适配（75%）的数据。散光软性角膜接触镜的处方比例范围从俄罗斯的 6%到葡萄牙的 48%。与球性软性角膜接触镜相比，散光软性角膜接触镜可被描述为以下特征：年龄较大（29.8 ± 11.4 岁比球性镜片 27.6 ± 10.8 岁）；男性占比较大（38%比 34%）；新适配的比例较高（39%比 32%）；硅水凝胶镜片的使用率较高（49%比 39%）；日戴型镜片的使用率较低（14%比 28%）。1996 年至 2011 年，散光软性角膜接触镜的处方量持续增加。2011 年的散光软性角膜接触镜适配比例与按购买力平价计算的人均国内生产总值呈正相关（r = 0.21；P = 0.004）。
目前，在所调查的大多数国家/地区，软性散光角膜接触镜的处方量不足以矫正所有戴镜者的临床显著散光（≥0.75 屈光度）。
