Contact lens fittings in a hospital-based practice are different from those in private practices because of specialised conditions. Few studies have been published on material preferences of such wearers, especially in long-term wearers. The aim of this study is to document contact lens prescribing trends in a hospital-based practice among long-term lens wearers and to identify their demographic profile.
Subjects reporting to a contact lens clinic of a tertiary eye-care centre in India from 1 January 2014 to 31 December 2014, with a minimum of five years of lens wear, were included in the study. Data were collected retrospectively from the electronic medical charts of these subjects.
Three hundred and sixty subjects were included in the study. The average duration of contact lens wear among the subjects was 9 ± 5 years (range: 5-35 years). The average age of the subjects was 31.38 ± 11.75 years (age range: 5-78 years). Hydrogel material and soft spherical type were preferred by most of the soft lens wearers (53 per cent). Eighty per cent of subjects followed hand hygiene and cleaning regimen practices.
The preference for monthly replacement lenses and silicone hydrogel material increased over the years. Regular after-care consultations could enforce the need for compliance with hand hygiene and cleaning regimens among lens wearers.
由于特殊情况，医院配镜与私人诊所配镜有所不同。关于这类佩戴者的材料偏好，尤其是长期佩戴者的材料偏好，鲜有研究发表。本研究旨在记录一家医院配镜诊所中，长期佩戴隐形眼镜者的配镜趋势，并确定他们的人口统计学特征。
纳入2014年1月1日至2014年12月31日期间，前往印度一家三级眼科护理中心的隐形眼镜诊所就诊，且至少佩戴隐形眼镜五年的受试者。数据从这些受试者的电子病历中回顾性收集。
360名受试者纳入研究。受试者佩戴隐形眼镜的平均时长为9±5年（范围：5至35年）。受试者的平均年龄为31.38±11.75岁（年龄范围：5至78岁）。大多数软性隐形眼镜佩戴者（53%）偏好水凝胶材料和软性球面型。80%的受试者遵循手部卫生和清洁方案。
多年来，对月抛型镜片和硅水凝胶材料的偏好有所增加。定期的随访咨询可以强化隐形眼镜佩戴者对手部卫生和清洁方案的依从性需求。
