While you may not have heard about it until recently, ortho-K and myopia control has been recognized and studied for many years. Both doctors and patients should be interested in the safety and effectiveness of any treatment. The studies below describe the research that has gone into understanding myopia and how is can be treated, prevented from progressing and even temporarily reversed.
