ortokläätsed

Ortokläätsed, also known as orthokeratology lenses or ortho-k, are specially designed rigid gas permeable contact lenses that are worn overnight. They are used to temporarily correct refractive errors, primarily myopia (nearsightedness) and astigmatism. The lenses gently reshape the cornea of the eye while the wearer sleeps. When the lenses are removed in the morning, the reshaped cornea allows light to focus correctly on the retina, resulting in clear vision throughout the day without the need for glasses or conventional contact lenses.

The orthokeratology process involves an initial fitting with a specialized eye care professional who measures the curvature of the patient's cornea. Based on these measurements, a custom-designed set of ortho-k lenses is created. Patients wear these lenses each night, and over a period of days or weeks, the cornea gradually adjusts to the desired shape. Regular follow-up appointments are necessary to monitor the effectiveness of the treatment and make any necessary adjustments to the lenses.

Orthokläätsed offer an alternative for individuals who want to reduce their dependence on vision correction during waking hours. They can be a good option for athletes, swimmers, or individuals who find glasses or soft contact lenses inconvenient. However, the effectiveness and suitability of orthokeratology vary from person to person. It is crucial to consult with an optometrist or ophthalmologist to determine if ortho-k is an appropriate treatment for individual vision needs. Potential risks and benefits should be discussed thoroughly with a qualified eye care professional before commencing treatment.
