Corneal Reshaping Therapy (CRT), aka Orthokeratology, is a process where myopia (nearsightedness) and mild astigmatism can be temporarily corrected by wearing specially designed rigid extend wear gas permeable lenses during sleep. The goal to achieve normal vision during the day without the use of corrective spectacles or other contacts is generally achieved. Due to the combinations of individual's anatomies and the corresponding prescriptions, the process typically takes a range of a few days to a few weeks. Several office visits are involved and possibly several lens changes may occur. However, the initial global fee discussed during the initial consultation will not change once the process has started.
This treatment is applicable to both children and adults, where other than maturity and willingness of the patient, there is no age limit. At Vision Care Center, we find that the age of 7 years old tends to be our youngest successful patient. There is no upper age limit. The amount of spectacle correction is generally the limiting factor.
CRT has shown to help maintain the current level of myopia from its probable continuation to escalate with proper maintenance of the lens. This has proven true for the majority of out CRT population. Other factors such as general binocular dysfunction can limit its success to stabilize the Rx.
Insurances may or may not cover this process, although those with contact lens allowances typically pay towards the maximum benefits for their plan.
