MYOPIA CONTROL: SUPPORTING RESEARCH
1) Pharmacological agents (low-dose atropine eyedrops) offer most effective myopia control

High-dose, moderate-dose and low-dose atropine showed the best control of myopia progression, according to a study recently published in Ophthalmology.
In their meta-analysis of 30 randomized control trials, Huang and colleagues also concluded that pirenzepine, orthokeratology, peripheral defocus modifying contact lenses, cyclopentolate and prismatic bifocal spectacle lenses showed moderate effects in myopia progression.
Progressive-addition spectacle lenses, bifocal spectacle lenses, peripheral defocus modifying spectacle lenses and more outdoor activities resulted in weak effects, according to the researchers. Gas-permeable contact lenses, soft contact lenses, undercorrected single vision spectacle lenses and timolol were ineffective.
The researchers concluded that low-dose atropine, pirenzepine and soft contact lenses with myopia control features are the best options for managing myopia progression.
2) The estimated prevalence of myopia (nearsightedness) in people between 12 to 54 years of age has increased from 25% in 1971 to 42% in 2004.

3) Multifocal soft contact lenses with distance-focus center and near-focus periphery have been shown to decrease the rate of myopia increase by 40-50%.

4) Daily use of Atropine eyedrops at dosages as low as 0.01% have the ability to slow myopia by 70 % or more without significant pupil dilation or blurred vision, and the effect persists after stopping treatment.
