Clinical observation of 152 myopic children wearing ordinary lens,progressive lens and non-focal glasses

Objective:To observe the influence of general concave lens,progressive addition lenses and no corrective lens on the refractive change of children and adolescents. Methods:152 cases of out-patients myopic children(304 eyes) from March 2007 to December 2008 whose myopia extend 0.50 to 2.0 DS,excluding other eye diseases except refractive errors,was treated with 0.5% tropicamide mydriatic to detect refractive optometry. Next day the cases were randomly divided into 3 groups:53 cases(106 eyes) who wear normal concave lens of 1.0 corrected visual acuity;51 cases(102 eyes) who wear progressive multifocal lenses of +1.5D addition;48 cases(96 eyes) who do not wear the correct lens. And reviewed the refractive optometry 6 months and 12 months after the referral. Results:3 times refraction results showed that there was no significant difference between groups(all P0.05) . Conclusion:The concave lens or progressive multifocal lens could not slow down the development of myopia in children and adolescents.
