Orthokeratology lenses, also known as ortho-k, are rigid gas-permeable contact lenses that are worn overnight to temporarily reshape the cornea and correct vision. They are primarily used to correct myopia, but can also be used to treat farsightedness and astigmatism.
The principle of orthokeratological lenses is based on changing the curvature of the cornea during sleep, which improves vision during the day without the need for glasses or contact lenses. The effects of orthokeratology lenses are temporary and reversible, meaning that the cornea will return to its original shape if lens wear is discontinued.
Orthokeratological lenses are particularly popular with people who do not want to wear glasses or contact lenses during the day, as well as athletes and people whose professions or hobbies make wearing glasses or contact lenses difficult. They can also be an interesting alternative to refractive surgery for people who are not good candidates for this type of procedure.
If you are interested in orthokeratology lenses, consult an eye care professional to learn more about how they work and determine if they are right for your needs. Regular fitting and monitoring are essential to ensure the effectiveness and safety of orthokeratology lenses.
