Orthokeratology
Effectively slows down the progression
of myopia
Orthokeratology what is it and how does it work?
Night vision correction is the most modern type of contact correction of myopia and farsightedness. These are special lenses that have the shape of a reverse geometry. The special design of these lenses provides 100% vision after 6-8 hours of wearing them without any additional correction for a long time (24 or more hours). They are used at night - in sleep. After sleep, the lenses are removed, while achieving 100% vision for the next 24 hours (without additional glasses and lenses).
Myopia Management
Results of clinical trials carried out in various countries have convincingly proved that orthokeratology inhibits the true progression of myopia (up to 76%) i.e. significantly slows down the increase in the axial length of the eye.
High myopia causes a noticeable decrease in the quality of life due to the difficulty in reading and seeing the world around you, leading to a dependence on means of vision correction.
Extreme myopia is fraught with serious complications such as retinal detachment and myopic retinopathy, which leads to irreversible changes and significant decrease in visual acuity. Complications of myopia occupy a key position in the list of causes of visual disability.
Early adoption of therapy is important in reducing visual fatigue and improving the quality of vision, which is central in the management of myopic conditions in children and adolescents.
What is the reason for this amazing effect?
The lenses have two distinct surfaces.
The outer surface is optical - it actively refracts light (like ordinary lenses) and makes it possible to get 100% vision in them. The inner one has a complex surface that actively affects the profile of the tear film. At the same time, the surface relief of the cornea and its refractive power change to the exact required amount.
When the patient removes the lens, the effect of changing the optical power of the cornea is preserved, the image is focused on the retina and the person sees well.
The effect of night correction (refractive therapy) is essentially similar to laser vision correction - a change in the refractive power of the cornea, with the difference that the effect is temporary.
Thus, with refractive therapy, without laser vision correction, you get the same effect - 100% vision within 24 hours. The temporary effect is explained by the constant renewal of the surface cells of the cornea.

Correct selection of night lenses
Correct selection of night lenses requires preliminary special diagnosis.
Each patient who is prescribed lenses undergoes a complete ophthalmological examination, which provides an opportunity to study all the individual features of the cornea.
After the doctor receives the results of the examinations, the possibility and feasibility of prescribing you refractive therapy will be discussed.
Selecting lenses is a painstaking and time-consuming task.
The patient is given a series of tests with the lens to assess the correctness and adequacy of the selection, and therefore to predict the effectiveness of its action.
When choosing, three anatomical parameters of the cornea are evaluated, for each of which four lens options are offered. And this means that for each eye there are 12 theoretical options, from which you need to choose the optimal one.
The effectiveness of night lenses depends entirely on the correctness of their selection and the experience of the doctor.
The fitting process requires several visits to the clinic (the first consultation and fitting of the lenses, the review after the first night of use, and the review after the first week and first month). The absence or delays in consultations can increase the adaptation time. When the fitting is complete, regular consultations are necessary to ensure that you do not have any problems with the health of your eyes and the quality of your lenses.
