Clinical Trial Summary

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.

Description:

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.

• Be aged 18-21 years at the start of the study
• Show evidence of recent myopia progression prior to commencement of Stage 2 of the study.
• Have read the patient information sheet and be happy to sign the consent forms
