Understanding… Orthokeratology 

Who has ever heard of orthokeratology ? This technique of prolonged wearing of rigid lenses at night may well be the solution to your vision problems at any age. By modifying the curvature of the cornea while you are sleeping, these lenses allow you to correct your vision all day long, without going through laser surgery. In this article, you will discover what orthokeratology is, who it is intended for, for which vision problems, and how to make an appointment. Read on !

What is orthokeratology ?

Orthokeratology is one of the techniques performed by our contactologist [contactologist page link]. By prescribing rigid contact lenses to be worn only during the night, the cornea is remodeled while you sleep. This type of lens corrects optical defects and gives you clear vision when you wake up.

Orthokeratology does not have the same effect as ophthalmologic surgery. Unlike refractive surgery, the corneal remodeling action of orthokeratology is reversible. If you do not wear your contact lenses for 24 to 48 hours, your cornea will return to its original shape, causing your vision problems to reappear.

To be more precise, orthokeratology is based on a nocturnal remodeling of the cornea where the rigid lenses will press between the eyelids and the lacrimal tears. A period of adaptation to the lenses is necessary, as well as learning the rules of hygiene from your contactologist. You will find in this article all the useful information concerning the 3 types of contactology appointment.

Who is orthokeratology intended for ?

Our COP9 contactologist proposes orthokeratology to all patients wishing to correct :

  • their myopia ;
  • their hyperopia ;
  • their presbyopia ;
  • their astigmatism.

Better yet, it is possible to slow down the evolution of myopia for younger patients thanks to early treatment with these rigid lenses. Orthokeratology is therefore suitable for all ages and all patients !

You may wonder why our patients make contactology appointments to get an orthokeratology prescription ? Here is a small list of examples that might encourage you to take the plunge:

  • stop wearing glasses;
  • avoid refractive surgery (eye surgery);
  • slowing down the progress of myopia (for younger patients);
  • difficulties with daytime lenses;
  • practicing any type of sport requiring good acuity without lenses or glasses.

People with sensitive eyes can rest assured that orthokeratology is also for them. You have probably tried different types of contact lenses and experienced discomfort (dry eyes, poor binocular vision, headaches) ? Getting used to rigid orthokeratology lenses is easier, and is done while you are sleeping. 

Don’t hesitate to make an appointment at our COP9 multidisciplinary center and talk to our contactologist about orthokeratology. Orthokeratology is the solution to correct certain optical defects in a painless way!

Does orthokeratology cure vision ?

Orthokeratology can compensate for the vision and allow night-time lens wearers to see clearly, provided they wear them rigorously and regularly. However, it does not provide long-term vision correction like myopia surgery.

This technique allows to compensate up to :

  • – 7 dioptres for myopia ;
  • + 4 diopters for hyperopia ;
  • – 4 dioptres for astigmatism ;
  • + 3 diopters for presbyopia. 

As a reminder, the diopter is the unit of measurement used by ophthalmologists (and eye care specialists) to indicate the correction required to obtain a visual correction.

Orthokeratology is particularly recommended for children and adolescents with myopia: at this age, their vision changes rapidly and sometimes irregularly. Wearing lenses at night can slow down these complex changes of the cornea.

Nevertheless, Dr. Stephanie Zwillinger and her contactologist would like to remind you that each patient is unique, and that the slowing down effect of orthokeratology differs from one young person to another.

To optimize this ophthalmological treatment, the COP9 team also invites you to read our advice in this article in order to take good care of young people’s vision, which will guarantee them an effective correction of their optical defects.

Does COP9 practice orthokeratology in Paris ?

As a multidisciplinary vision and psychomotor center, Dr. Stephanie Zwillinger has recruited a contactology specialist to meet your orthokeratology needs in Paris.

During your ophthalmological check-up, you also have the possibility to talk with our ophthalmologist to find out if your optical defect (myopic, presbyopic, hyperopic, etc.) and degree of correction can correspond to this ophthalmological care.

It is possible to make an appointment with our contactologist online or through our Contact page. Present in our practice located at 76 rue Saint Lazare in Paris 9, our contactologist evaluates the possibility of prescribing you rigid lenses in order to offer you better visual acuity. They work in conjunction with our ophthalmologist, whom they can consult if necessary to provide you with a complete coordinated care program.

Thanks to orthokeratology, you will only have to go to contactology appointments at the COP9 practice, order your rigid lenses from your optician, and of course have a regular check-up of your visual acuity with your ophthalmologist. And then you can say goodbye to glasses and contact lenses!
