New studies are proving how different designs for orthokeratology molds can impact nearsighted progression.
For adults it may be best to create a design that maximizes the central treatment area. This usually results in better night vision for driving. However, in children a smaller central treatment zone is preferred. Studies are finding that the smaller area aids in slowing the progression of myopia. Most young children benefit by remaining stable at a lower degree of nearsightedness. This benefit continues in to the adult years, help reduce the risks associated with higher myopia. An Orthokeratologist treats children with molds to both, improve current vision and slow or stop the progression.
