Lenses for night wear “Paragon”

линзы ночного ношения paragon

PARAGON are the first night wear lenses that correct your vision while you sleep. Today, orthokeratology is the most modern method of contact correction of myopia and astigmatism.

The method of vision correction using Paragon orthokeratological lenses was certified in 2002 in the USA (FDA approval) and the countries of the united Europe (CE). For three years, specialists have conducted clinical trials that have proven the complete safety of the use of Paragon night lenses. They can be recommended to patients from the age of six.

The Ministry of Health of Ukraine in 2005 issued a certificate for the use of Paragon orthokeratological lenses in refractive therapy. Starting this year, night wear lenses are also available at the Excimer Ophthalmological Center.

What makes Paragon night wear lenses unique?

The cornea is the transparent membrane that covers the front of the eye. There are no blood vessels in it, it has a high refractive power and enters the optical system of the eye. The cornea borders on the opaque outer shell of the eye – the sclera.

Paragon Night Wear Contact Lenses for vision correction provide temporary relief from myopia (nearsightedness) by reshaping (flattening) the cornea, which is elastic in nature. A slight decrease in the curvature of the cornea reduces the excessive focusing ability of the myopic eye and completely compensates for myopia.

How do night wear lenses work?

Night wear lenses, like regular contact lenses, are placed directly on the mucous layer of the cornea. However, due to the special design and shape of the reverse geometry during the time you sleep, the lenses gently affect the shape of the cornea, thereby temporarily improving vision due to a reversible change in the curvature of the cornea. Clinical trials prove that after 6–8 hours of wearing the lens, the cornea retains its changed shape for a long period of wakefulness of a person (up to 24 hours), so there is no need for additional correction (glasses, contact lenses) during the day. Night lenses to restore vision are put on 10-15 minutes before bedtime.

What material are night wear lenses made of?

Modern gas permeable lens material is a complex composite: purified fluoro-silicone-acrylate. Each of the materials provides its own function: fluorine – additional strength, and silicone – oxygen permeability.

How long can these lenses be used?

Night wear lenses last 1 year. After this period, the oxygen permeability of the lens decreases. If everything suits you, then you can continue to use the same lens model. The only thing you will need to do is to undergo a complete diagnostic examination in order to make sure that your vision has not changed.

Night lenses contraindications

Night lenses to improve vision are contraindicated in the presence of:

  • conjunctivitis and other infectious diseases;
  • severe dry eye syndrome and if hard lenses cause constant discomfort;
  • myopia above -6 diopters and astigmatism more than 1.75 diopters;
  • diseases of the cornea, including inflammatory.

For whom can orthokeratology (night wear lenses) be recommended?

  1. Patients with refraction from -0.5 to -6.0 D.
  2. Patients with astigmatism up to -1.75 D.
  3. Those who, due to professional conditions (dust, temperature fluctuations, high humidity, dry and hot climate), cannot use glasses or daily contact lenses.
  4. People with intolerance to soft contact lenses (allergic reaction, oxygen starvation of the cornea, vascular ingrowth into the cornea, a pronounced decrease in the sensitivity of the cornea, dry eye syndrome).
  5. For those who cannot undergo laser vision correction due to a too thin cornea.
  6. Patients aged 6 to 40 years.

Do I need to see a doctor to fit lenses for night wear?

The selection of lenses is a very important step, which should be carried out only by a doctor based on the results of diagnostics using modern equipment. It is important that the doctor has experience in refractive therapy and is a certified orthokeratologist.

In our clinic, the selection of night lenses is carried out by the chief physician of the pediatric ophthalmology clinic “Excimer KIDS” in Kyiv and the head of the department of refractive surgery – Prozhoga Sergey Anatolyevich – a doctor of the highest category and Varga Elena Yuryevna – a leading specialist in the children’s department, an ophthalmologist of the first category, a member of the association children’s ophthalmologists of Ukraine “ADOU”. Our specialists have been trained, have all the necessary certificates and permits.

What is important to remember!

  1. An examination by a doctor is required on the 2nd day after the selection of lenses. This should not be a late appointment, since you need to come to the clinic with the lenses installed (that is, do not remove them in the morning).
  2. To ensure that night medical contact lenses do not cause you discomfort, you need to visit an ophthalmologist regularly. Mandatory examinations at the Excimer clinic are carried out both on the second day and after a week, a month, and then once every three months during the year.
  3. If you put on the lenses for the first time and you have a foreign body sensation, DO NOT go to sleep with such a sensation. You need to remove the lens, rinse it, moisten it and reinstall it. If the unpleasant sensation has not disappeared, it is not recommended to wear the lens.
  4. High-quality and proven night medical contact lenses you should buy only in a specialized clinic.
  5. It is equally important to properly store and handle contact lenses, you can not exceed the period of their wearing and storage.

Benefits of night wear lenses

  1. When wearing Paragon lenses, the eye breathes atmospheric oxygen during the day, as usual, while with daily contact lenses, corneal breathing is significantly reduced. Therefore, with refractive therapy, there is no state of hypoxia (oxygen starvation), which can lead to ingrowth of blood vessels into the cornea (neovascularization).
  2. When wearing Paragon lenses, tear circulation is not disturbed. Consequently, a tear removes soluble waste products, dust particles, smoke from the cornea, and also transports nutrients to it.
  3. Refractive therapy with Paragon lenses eliminates the limitations associated with wearing glasses and soft contact lenses. You can run, jump, rub your eyes, and also eliminate the psychological problems in children associated with wearing glasses.

Night wear lenses are safe!

According to statistics, among those who use refractive therapy, 80% are children, because up to 18 years of age refractive surgery (excimer laser correction) is not performed. World experience has shown that in children using Paragon orthokeratological lenses, the progression of myopia slows down, and in 40% of cases it stops completely.

Prices for orthokeratology

The cost in Kyiv of the Orthokeratology service at the Excimer ophthalmological clinic includes an annual service:

  • one pair of lenses + solution;
  • consultation, selection, training;
  • scheduled examinations during the year (on the 2nd day, in a week, in a month, then – 1 time in 3 months).
