Singapore Myopia Treatment Study: Asian RGP Contact Lens
Myopia is the commonest vision disorder in humans. The prevalence of myopia is 25–75% depending on demographics, age, and level of education. Correction of myopic refractive error is effected by the use of spectacles, rigid or soft contact lenses, and refractive surgery. Of these modalities, only rigid lenses have been reported to have an effect on stabilizing the progressive nature of early-onset myopia. A randomized, controlled clinical trial to test this hypothesis is being conducted on 300 progressive myopes between the ages of 8 and 11 years in Singapore.
