What are night lenses?

Orthokeratology lenses are designed to temporarily change the surface of the cornea to correct incorrect refraction during the day. Unlike conventional contact optics, they have a rigid structure that retains its shape during use. This allows you to create a slight pressure on the surface of the cornea, under the influence of which its curvature changes. As a result, by morning the corneal surface has a new anatomically correct shape. After removing the lenses during daylight hours, it slowly recovers to its original state, nevertheless providing clear, clear vision.

Night correction lenses are made from high-tech materials based on hydrogels and silicone. The structure has high gas permeability, allowing the cornea to freely receive oxygen from the air. Even the most modern soft models cannot boast of such characteristics.

General information

Advantages and disadvantages of night vision correction

Orthokeratology is widely used by ophthalmologists to treat children's eyes, because... has improved qualities that distinguish it favorably from other therapeutic methods.

Children's night lenses are an effective way to prevent myopia. The corrective effect allows you to restrain the pathological deformation of the eyeball, which is very important during the period of active growth.

Thanks to reliable fixation, the lenses provide stable vision correction performance. The use of optics does not interfere with the natural circulation of ocular fluid, reducing the risk of dry keratitis. In addition, hard lenses are more resistant to damage than soft contact lenses and are more convenient to put on and take off.

Using orthokeratology optics at night eliminates the need to wear glasses during the day. The child does not experience psychological discomfort or other complexes; he feels free and confident among his peers, leading a normal lifestyle.

Night lenses for vision correction in children create a short-term effect, the maintenance of which depends only on systematic wearing. If such a correction does not work, it can always be stopped and replaced with other types of therapy.

The materials used to make lenses are safe and do not cause allergic reactions.


Disadvantages:

The disadvantages of the method include a long adaptation period associated with some discomfort and pain, which disappear over time. In addition, rigid products require a long and careful selection, because The corrective ability of the optics depends on the accuracy of the specified parameters.

Indications and contraindications

The use of night orthokeratology lenses is allowed for children from 6 years of age. The method is used in therapy:

  • Myopia up to -6 diopters.
  • Farsightedness up to 4 diopters.
  • Astigmatism up to 5 diopters.
  • Progressive refractive errors.

It is advisable to use ortholenses in the treatment of false myopia, when the onset of pathological processes is still reversible, but can become active without timely treatment.

In some cases, children do not wear soft contact lenses. This is due to the reluctance of such treatment or individual intolerance to the components of the optics. Orthokeratological correction, however, is an excellent option that satisfies most requirements.

However, not everyone without exception is recommended to wear corrective lenses at night. The products are not used if the small patient has:

  • Inflammatory diseases of the eyelids, cornea, conjunctiva
  • Keratoconus or keratoglobus
  • Glaucoma
  • Cataract
  • Epitheliopathies of any severity
  • Severe form of dry eye syndrome.

Orthokeratology is also contraindicated in cases of previous ophthalmological operations.

Duration of action and wearing mode

After the first overnight use, the corrective effect is up to 75%. After 7-10 days, vision improvement rates will be maximum - up to 85-95%. It should be noted that for patients with minor refractive errors, such optics are ineffective and therefore are not widely used.

To achieve a high level of correction, orthokeratology lenses must be worn constantly every night or every other night. They must be cleaned of bacterial and other contaminants by placing them in an ophthalmic solution for hard types of optics for a day. Some night samples contain moisturizing components that provide the necessary lubrication for more comfortable use. If the products do not have such properties, then they need additional moisturizing using special products.

The service life of one pair of lenses is 1 year. If treatment is canceled, complete restoration of the previous shape of the cornea will require 3-4 weeks.

Selection of night lenses

The selection process for orthokeratology optics includes several stages.

1

Diagnostics. During the initial consultation with an ophthalmologist, a comprehensive diagnosis of the condition of the visual organs is performed, visual acuity and the possibilities of its correction using orthokeratology are assessed. For these purposes, the following are indicated: keratotopography, keratometry, refractometry. Important! The examination is only advisable if the cornea has a natural shape. If you wear soft or hard contact lenses, their use should be stopped 2 weeks and a month, respectively, before the planned diagnosis.

2

Selection. Based on the monitoring data, the doctor calculates the individual parameters of products for production in the optical laboratory. The average order fulfillment time is about 2 weeks.

3

Fitting. At the next appointment, the doctor helps the patient put on the lenses and explains how to use them correctly. The patient needs to close his eyes for half an hour, simulating sleep, after which the vision is assessed again. The doctor clarifies how you feel, whether everything is okay, and sends you home with the lenses on.

4

Inspection after the first night. Diagnosis is performed after the lenses are removed.

5

Observation during operation. Further visits to the ophthalmologist are scheduled in 10 days, 1, 3, 6 months and a year later, when it’s time to change lenses. Then the entire selection process is repeated again.

Orthokeratology treatment has a low likelihood of complications. These are mainly infectious eye diseases caused by improper care or use of lenses.
