What is orthokeratology?
Orthokeratology is a vision correction treatment that reshapes your cornea while you sleep so that you have perfect vision during the day. No glasses, no contacts, no surgery. Orthokeratology is also sometimes caled "corneal reshaping", "corneal molding", "overnight vision correction" or "ortho-K". Orthokeratology is most effective for near sightedness and astigmatism. Lens designs for farsightedness are under development.
Not only does orthokeratology give you clear vision, it also slows or stops the progression of myopia, making it a popular choice for patients who find that their eye-glasses prescription is increasing every time they go to the eye doctor. Myopia progression can be very dangerous (it could lead to blindness) and any treatment that slows or stops the process is welcome.
Orthokeratology is very popular with people who are active in sports, especially swimming, people who don't like the discomfort of contact lenses and people who are tired of wearing glasses. It is also a good option for people who are not good candidates for laser eye surgery or who just don't like the idea of having elective surgery on their eyes.
The patient will wear custom designed rigid, oxygen hyperpermeable lens retainers while she sleeps (the retainers are very comfortable) and remove them in the morning. Sometimes there is a trial and error process to get the fit perfect and to ensure maximum effectiveness and comfort. During sleep, the retainer reshapes the cornea of the eye resulting in 20/20 vision upon waking. The retainer lenses must be worn every night and sometimes less frequently depending on how a particular patient's cornea responds to the retainer lens.
A doctor needs to initiate and supervise orthokeratology treatment to ensure the cornea is measured properly and accurately, that the lenses are doing their job properly, that the eyes are adapting well to the lenses and that there is no risk of damage is being done. Doctor supervised orthokeratology has proven to be very safe and effective.
