Otherwise known as corneal reshaping or corneal refractive therapy (CRT), orthokeratology allows people with mild to moderate nearsightedness to achieve 20/20 vision without needing to wear corrective lenses during the day. This makes it a great choice for people who don’t want the hassle of glasses or contact lenses and plan on having laser vision correction in the future for permanent results.
Orthokeratology, ortho-k for short, is a non-surgical method used to treat nearsightedness (myopia). Ortho-k lenses are rigid, gas-permeable lenses that are worn overnight to physically correct the curvature of the cornea resulting in light focusing onto the retina.
This allows patients to see clearly without using glasses or contacts during the day. It is also used to slow down the progression of nearsightedness, which puts patients at a higher risk for developing eye disease in the future.
Myopia is an elongation of the eye that causes objects that are farther away to appear blurry. Some other signs of myopia are frequent squinting or blinking, headaches, sitting closer to the television or computer, and holding books or tablets very close when reading.
Ortho-k lenses are custom-made for patients using high-definition scans of the eye. They are designed to physically press against the elongation and distortion of the cornea, pushing it into the correct shape for effective vision correction.
Depending on the amount of vision correction needed, people who use ortho-k lenses experience dramatic results in about a week or two. Those with greater distortion and higher prescriptions take longer to experience results compared to those with only slightly myopic corneal shapes.
The best candidates for orthokeratology are children age 8-12 with progressive myopia. However, there are no age restrictions. It is a highly successful option for most teenagers and adults below the age of 40.
Orthokeratology can treat prescriptions up to -6.00 with low to moderate astigmatism. It is a great option for children that play sports as they do not have to wear glasses or contact lenses during the day.
