A number of optical and pharmacological modalities have been widely investigated for restriction of myopia progression [2, 3]. Clinical trials on spectacles, rigid gas permeable contact lenses, progressive addition lenses, and soft contact lenses have revealed little or no long-term efficacy of these interventions in myopia control [4, 5]. Both tropicamide combined with bifocals and timolol have also failed to show a significant effect on slowing myopia progression [6, 7]. Two randomized controlled trials on pirenzepine revealed encouraging findings; however, research has not been continued for this agent [8–10]. Contradictory evidence exists regarding the effect of undercorrection on myopia progression. Two randomized controlled trials reported that undercorrection enhances myopia development [11, 12]. Recent evidence shows that undercorrection restricts myopia progression compared to full correction in already myopic children, which is in line with former findings from animal studies . Acupuncture has also been investigated for myopia control, but insufficient evidence exists regarding its appropriateness for clinical use .
