Long-term effects of hydrophilic contact lenses on myopia.

Myopic patients aged 14 to 19 years were divided randomly into two groups: those that wore contact lenses full time and those that wore spectacles only as age-matched controls. These two groups were analyzed statistically for any difference in the rate of progression of myopia. Refraction records were screened and analyzed using the unpaired Student's t test. We found no statistically significant difference between the two groups. There appears to be no effect of soft contact lens wear on the progression of myopia.
