Part-time Versus Full-time Spectacles for Myopia Control (ParMA Study)

Myopia Clinical Trial

Official title:
Part-time Versus Full-time Spectacles for Myopia Control (ParMA Study)

Clinical Trial Summary

The purpose is to assess the effect of part-time compared to full-time spectacle use in juvenile myopia control.

Clinical Trial Description

A prospective, randomized, controlled clinical trial was designed for assessing the effect of single-vision spectacles on myopic progression. 30 myopic subjects, aged 6-16 years old, with a spherical equivalent refraction between -0.50D and -6.00D, were recruited. A random number table was used to allocate participants into either a) part-time use of single-vision spectacles, or b) full-time use of single-vision spectacles. Part-time use was for 4-6 hours a day, 7 days a week for a year. Clinical assessment included follow-up at 6 months and at 12 months upon allocation. The primary outcomes were a) change in spherical equivalent refraction (SER) measured by cycloplegic autorefraction, and b) change in axial eye length (AL). The secondary outcomes were a) change in choroidal thickness (ChT), and b) assessment of the subjective tolerance. ;
