A 3-year study on the effect of RGP contact lenses on myopic children.

Abstract

Recent studies in the West have shown that rigid gas-permeable (RGP) contact lenses can control the progress of myopia in children. These studies were done on Caucasian children, whose myopias are less rapidly progressive than those which we see in Singaporean children. This three-year study was started in 1993, with the following objectives: 1. To verify whether RGP contact lenses can control the progress of myopia in Singaporean children. 2. If so, to investigate the mechanism by which the lenses control myopia; whether by corneal flattening or by reducing the growth of the axial length. 3. If so, to assess if the effects are permanent, by discontinuing lens wear.
