ortokeratológia

Ortoqueratologia, often abbreviated as Ortho-K, is a non-surgical vision correction method that involves wearing specially designed rigid gas permeable contact lenses overnight. These lenses are worn while sleeping and gently reshape the cornea, the front surface of the eye. The reshaping temporarily corrects refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

When the wearer removes the lenses in the morning, they can see clearly throughout the day without the need for glasses or conventional contact lenses. The effects of Ortho-K are reversible; if lens wear is discontinued, the eye will gradually return to its original shape and refractive error. This reversibility makes Ortho-K an appealing option for individuals who dislike wearing glasses or daytime contact lenses, or for those who are not candidates for refractive surgery.

The fitting process for Ortho-K lenses is highly individualized, requiring precise measurements of the eye. An eye care professional carefully designs the lenses to achieve the desired visual outcome. Regular follow-up appointments are necessary to monitor eye health and the effectiveness of the treatment. While Ortho-K can provide freedom from vision correction devices during the day, it is crucial for wearers to maintain proper hygiene and follow their eye doctor's instructions to prevent potential eye infections or complications.
