Orthokeratology in Paris for everyone

Have you heard about orthokeratology?
Orthokeratology (also known as Ortho-K), is an innovative technique that uses specially designed contact lenses to reshape the cornea overnight.
Continue reading to discover how the orthokeratology fitting process unfolds with Solene, our contact lens specialist!
Orthokeratology is a specialized field within contact lens care, and lens fitting is performed by a qualified professional, whether an ophthalmologist or a certified contact lens specialist.
These professionals assess the patient’s cornea, determine the appropriate prescription, and monitor the orthokeratology adaptation to ensure optimal results while minimizing the risk of complications.
This method is mainly used to correct refractive errors such as myopia, astigmatism, hyperopia, and presbyopia.
It allows wearers to use contact lenses overnight and benefit from optimal visual acuity during the day, without the need for glasses or daytime lenses.
Discover how the orthokeratology fitting process is conducted at COP9!
The process begins with a consultation with our ophthalmologist, Dr. Stéphanie Zwillinger, who performs a complete eye check-up, together with her team of orthoptists (Margot Joyau and Justine Paludetto).
This includes visual acuity tests and an analysis of the corneal curvature using corneal topography.
You will then discuss with Dr. Stéphanie Zwillinger the possibility of wearing overnight lenses. She will also assess the degree of correction needed to ensure orthokeratology is a viable option for you.
You will then meet our contact lens specialist, Solène Dezaniaux.
It is important to note that orthokeratology is not suitable for all patients!…
Certain contraindications—such as specific ocular diseases or an irregular cornea—may prevent successful lens fitting.
Our specialist will determine the most appropriate type of contact lens based on your individual needs and lifestyle: rigid or soft, toric or spherical, daily or monthly lenses
After the evaluation, if orthokeratology is deemed suitable for the patient, our contact lens specialist will prescribe corneal contact lenses to be worn during the night.
These lenses are specifically designed for orthokeratology—a non-surgical optical correction technique.
Unlike daily or soft contact lenses, lenses used in orthokeratology are rigid and custom-made.
They are usually made from silicone hydrogel to ensure high oxygen permeability, which is essential for corneal health.
Rigid lenses are often preferred in orthokeratology for their ability to reshape the cornea effectively.
Although it is helpful to understand the variety of contact lenses available, orthokeratology specifically uses rigid gas-permeable lenses (RGPs).
These lenses apply controlled pressure to the cornea during sleep, temporarily reshaping its curvature and enabling clear vision throughout the day without the need for glasses or contact lenses.
Once the lenses have been prescribed, the patient proceeds with the first lens fitting.
It is essential to learn how to properly handle the lenses, rinse them, and strictly follow the care instructions provided by our contact lens specialist.
Wearing contact lenses requires a period of adjustment, particularly in the case of orthokeratology.
During the first few days, patients may experience discomfort or slight irritation, but this is generally temporary.
It is recommended to wear the lenses every night for extended periods, allowing the cornea to gradually adapt.
Your contact lens specialist will schedule follow-up appointments to monitor visual progress and make any necessary adjustments.
Results may vary from one individual to another—some patients notice a significant improvement in visual acuity within the first few days, while others may require a longer adaptation period.
An essential aspect of orthokeratology is proper lens maintenance.
Wearers must use an appropriate cleaning solution to disinfect and hydrate the lenses, ensuring effective decontamination.
The cleaning solution should be regularly refreshed to prevent deposits or the accumulation of foreign bodies under the lens.
Washing your hands thoroughly before handling the lenses is crucial to minimize the risk of infection.
Using tap water to clean the lenses is strongly discouraged due to the presence of bacteria and other microorganisms that increase the risk of eye infections.
Rinsing lenses with sterile saline solution may be used to remove residue prior to disinfection.
The cleaning solution must be regularly renewed to avoid deposits or the formation of debris beneath the lens.
Wearing lenses for extended periods without proper care can lead to complications and significantly increase the risk of infection.
It is therefore imperative to follow your contact lens specialist’s recommendations regarding cleaning, disinfection, and the frequency of solution replacement.
After the initial adaptation, regular follow-up with your ophthalmologist is essential to:
Monitor the condition of the cornea;
Prevent complications such as keratitis or conjunctivitis;
Adjust the prescription if necessary.
In addition to ophthalmologic follow-up, the optician may also play a role in orthokeratology adaptation by offering care advice and checking lens fit.
Depending on how the eye responds to treatment, the specialist may recommend more or less frequent visits.
Orthokeratology lenses are designed to be comfortable for overnight wear, minimizing sleep disturbances.
Their silicone hydrogel material promotes excellent corneal oxygenation, reducing the risk of dry eye and other complications.
Unlike traditional contact lenses, they provide a natural field of vision throughout the day, without the need for glasses or contact lenses during waking hours.
By temporarily reshaping the cornea, they enhance visual clarity and help reduce dry eye symptoms often associated with refractive conditions.
The adaptation process in orthokeratology requires commitment and good communication between the patient and their eye care professional.
With proper preliminary consultations, an accurate prescription, and regular follow-up care, lens wearers can enjoy clear near and distance vision throughout the day—without glasses or daytime lenses—while minimizing the risk of discomfort or infection.
By choosing this type of lens, patients can significantly improve their quality of life while preserving long-term eye health.
