Orthokeratology (ortho-k) is a non-surgical method for the temporary correction of myopia (nearsightedness), hyperopia (farsightedness), and astigmatism using specially designed gas-permeable contact lenses that are worn overnight.
Ortho-k lenses work by gently reshaping the cornea while the wearer sleeps, correcting vision for the next day. These lenses are typically removed upon waking, and the wearer can enjoy clear vision throughout the day without needing glasses or contacts.
The lenses need to be worn consistently to maintain their effect, and the cornea will gradually return to its original shape if ortho-k is discontinued. Ortho-k is not a permanent solution for vision correction, but it can provide a temporary solution for people who do not want to wear glasses or contacts during the day.
In addition to providing temporary vision correction, orthokeratology has also been shown to potentially slow down the progression of myopia in children. Ortho-k lenses have been shown to potentially slow down the progression of myopia in children by reducing the elongation of the eyeball that is associated with myopia progression.
Ortho-k lenses are a great option for active people who may have difficulty with glasses or traditional contact lenses. They can also be a good choice for children who are too young for refractive surgery.
It's important to note that ortho-k lenses should be prescribed and monitored by an eye care professional to ensure proper fit and eye health. If you're interested in learning more about ortho-k or determining if it may be right for you or your child, be sure to consult with an eye care professional.
