A number of studies regarding the effect of orthokeratology (OK) on myopia progression have been published and shown that it can slow myopia progression in school-aged children. Recently, OK has been considered to be one of the most effective optical treatments for myopia control. This article reviewed the peer-reviewed literature on the efficacy of OK for myopia control. Although it cannot halt myopia progression completely, the inhibitory effect on axial elongation for 2 years has been reported to be from 32% to 63%, as compared with single-vision spectacles and contact lenses. In addition, the efficacy and acceptable safety have been confirmed even in several long-term studies up to 10 years. However, the possibility of a rebound phenomenon in myopia progression after OK discontinuation remains unknown. It is also unclear how long the treatment should be continued to attain the maximum benefit in each patient. In the near future, further research including assessment of rebound phenomenon should be conducted with longer follow-up periods in more diverse populations.
