Orthokeratology lenses, also known as rigid night lenses, are specially designed to gently reshape the cornea to improve visual acuity. They are made from a special gas-permeable material and are completely safe when used and cared for properly.
- want to slow the progression of myopia;
- prefer not to wear glasses or soft contact lenses for certain reasons;
- have dry eye syndrome;
- have specific professional requirements, such as drivers, military personnel, athletes, or dancers.
Indications for orthokeratology therapy:
- myopia (nearsightedness) up to -7 diopters;
- astigmatism up to -4 diopters;
- hyperopia (farsightedness) up to +4 diopters;
- pseudomyopia (accommodation spasm);
- “lazy eye” (amblyopia).
How does it work?
All you need to do is wear the lenses overnight. Thanks to their special shape, they gently reshape the corneal epithelium, changing its form and, consequently, its optical power. The effect is applied precisely where needed, as the lenses are individually fitted based on a corneal topography map.
It is important to note that this refractive therapy is temporary, reversible, and completely safe. The lens material has undergone all clinical tests and allows oxygen to reach the cornea, while the corneal anatomy and epithelial integrity remain unaffected.
Fitting process:
- 1. The doctor examines and consults the patient.
- 2. Performs corneal topography — an examination using a specialized device that measures corneal thickness, refractive power, and creates a “map” of the cornea.
- 3. Determines whether orthokeratology therapy is suitable.
- 4. Selects lenses based on the topography results.
- 5. Teaches the patient how to insert, remove, and care for the lenses.
- 6. Schedules follow-up visits.
Which manufacturer/brand?
We provide high-quality MoonLens orthokeratology lenses from KATT Design Group Inc. (Canada). MoonLens were among the first in the world to receive FDA approval for overnight wear back in 2004 and remain a market leader. MoonLens are a reliable choice for orthokeratology therapy because:
- They have many years of experience in use (in over 60 countries);
- They ensure stable and predictable results;
- They require a high level of professional expertise and modern equipment;
- They provide maximum therapy effectiveness.
Frequently asked questions:
Vision correction can reach up to 100%. In some cases, it may be up to 80%, which still allows you to perform daily activities comfortably without glasses or soft contact lenses.
Visual acuity improves gradually. Some patients achieve high clarity within the first few days, while others may take 10–14 days. The higher the degree of myopia, the longer it may take to reach optimal vision.
From 6 years old.
The risks of wearing orthokeratology lenses are the same as with regular soft contact lenses. When proper lens care is followed, the risks are minimal.
No, wearing rigid night lenses is painless. You may feel the lens on your eye during the first few days, but this sensation will gradually disappear.
One orthokeratology lens costs 7,200–7,900 UAH. It is also possible to order custom lenses from the manufacturer.
Lenses should be replaced once a year. Over time, oxygen permeability decreases, so wearing them beyond their recommended period can be unsafe.
Yes, there are:
Severe dry eye syndrome;
Inflammatory diseases of the eyes or eyelids;
Corneal dystrophies, opacities, or scarring;
Endocrine or oncological diseases.
Orthokeratology therapy is a truly reliable method to slow the progression of myopia in the hands of an experienced doctor. The first step is an assessment of vision and the cornea.
