Обзор
The purpose of the study is to quantify the effectiveness of Coopervision MiSight contact lenses in slowing the rate of myopia progression in university students.
Подробное описание
MiSight contact lenses have been shown to be a safe and effective way of managing myopia progression in children aged 8-12 years. However, myopic progression is not limited to children of this age group and MiSight lenses have also been shown to be effective in older children aged 11-16 years. There is evidence that progression also occurs in university students. The researchers are therefore investigating the effectiveness of this intervention in a group of UK-based University students.
