Russian manufacturers of contact lenses

Russian companies producing contact lenses and care products occupy a very modest place in the contact correction market, which is explained by their predominant focus on traditional contact lenses, while throughout the world there is a transition from traditional lenses to frequent replacement lenses and daily contact lenses. However, the products of domestic manufacturers are certainly in demand:

Firstly, the price of domestic lenses is quite low.

Secondly, Russian companies offer lenses of large diopters from -20 to +20; lenses of such large refractions are simply not available in the product line of Western companies.

Thirdly, product quality control in Russian companies is more stringent, which makes it possible to timely identify and eliminate defective products and ultimately obtain high-quality contact lenses.

Concor is the largest domestic company producing contact lenses. The company appeared in 1991 in the city of Vologda. Today the company supplies products in more than 400 cities Russian Federation, Ukraine, Kazakhstan, Belarus, Bulgaria.

Today the company produces soft contact lenses from imported and domestic materials, including silicone hydrogel, tint and color.

Contact lenses are a medical product that allows for the correction of various abnormalities resulting from eye diseases. Most often, you can find products on sale that are made with people in mind who suffer from myopia (myopia), that is, those who have difficulty seeing at a distance. For patients with farsightedness (hyperopia) there are also models, it’s just that there are much fewer people with such a vision defect. Yes, and myopic people actually have to large quantity spend time wearing glasses/lenses so as not to experience discomfort in Everyday life. There are also options for correcting astigmatism.

You can select lenses for yourself only after visiting a specialist who will conduct a full examination and write out a prescription. Even if you have been a user for many years, before changing one brand to another, do not be lazy to visit an ophthalmologist. Contact lenses different manufacturers and different lines differ from each other in “design”. This concept usually includes parameters of the shape of the front and back surfaces, diameter, thickness at the center, base radius, and so on. It is also wrong to select lenses according to your glasses prescription, since their optical powers are different. Our rating will tell you about the best contact lenses in their categories.

Today there are many ways to correct vision. Very often, contact lenses are used to improve its severity and eliminate other problems. Depending on the type of material, soft and hard gas permeable contact lenses are distinguished. Of course, the first type is most often used, however, the latter also have many advantages.

Materials for making hard lenses

Rigid lenses became widespread at the end of the twentieth century. Then the main material for their manufacture was polymethyl methacrylate. The lens itself was relatively small in size. The disadvantage of such lenses was the lack of gas exchange. Access of oxygen to the cornea was achieved only due to the mobility and small size of such a correction device. However, today more modern and high-quality materials are used. Rigid gas permeable contact lenses are made from fluoro-silicone compounds. Thanks to this, the lenses have good oxygen permeability. It is worth noting that they are quite comfortable, they are made individually, and an exact fit is made for a specific patient.

Indications for the use of hard lenses

Soft contact lenses have limitations in their optical power range. They are often prescribed for myopia up to -12 diopters, myopia no higher than 8 diopters. More strong degree Myopia requires specific correction. Soft lenses with high optical powers will have considerable thickness in this case. This, in turn, increases the risk of complications (tight fit can lead to eye hypoxia). You can, of course, use glasses, but today experts offer modern rigid gas-permeable contact lenses. They have wide range refraction - from -25 diopters to +25 units. The use of modern material ensures sufficient oxygen supply to the eye. Moreover, the thickness of such lenses is not much different from the corresponding parameters of soft products for vision correction.

Hard Lens Design

Modern hard lenses have an optical zone that is located in the center of the product. Its diameter does not exceed 8 mm. Thanks to the sliding zone, which has a specific structure, the lens is securely fixed on eyeball. The marginal region has the smallest dimensions. It is she who is responsible for comfortable wearing of the product, provides normal exchange tear fluid under the lens.

The main advantages of these lenses

Many patients note that rigid gas-permeable rigid lenses are less susceptible to deformation and creasing. Due to the fact that their diameter is slightly smaller than that of soft lenses, such products leave the peripheral zone of the cornea open. This, in turn, does not disrupt the tear exchange process. They are also more resistant to protein deposits, so the period of safe operation increases. Since the composition is completely free of water, hard lenses cannot dry out, the patient does not need to use special moisturizing drops. It is important to note their cost-effectiveness: the indication for replacement is only a change in visual acuity. For astigmatism, hard lenses are also indicated; patients indicate that correction with soft lenses in this case is quite difficult; the only option is to use hard products. Orthokeratological correction is also widespread. It involves the use hard lenses only at night.

Orthokeratology. What is the essence of the technique

This type of vision correction allows you to maintain your vision sharpness during the day, but at night you need to wear special lenses. During sleep, the cornea of ​​the eye changes; its optical zone becomes flatter. This form remains for the next day. As a rule, the effect of such a correction can last two days. good for children, patients with a progressive form of myopia, if there are contraindications for the procedure. Also, this method is often chosen by people of certain professions: athletes, military, builders, etc. Contraindications to orthokeratological therapy are diseases of the cornea, eyelids, all kinds of inflammatory processes, syndrome "dry eye"

Disadvantages of using hard lenses

In addition to the above advantages, hard lenses also have their disadvantages. First of all, a certain period of adaptation is required (about a week). After getting used to it, the discomfort disappears, but even a short break in wearing requires new getting used to the products. Some degree of corneal deformation is observed if rigid gas permeable contact lenses have been used. Reviews from patients indicate that using glasses after such lenses does not bring the desired result: the image becomes blurry and the sharpness decreases. However, this is a temporary effect. After the cornea has been restored, you can safely use glasses without losing the quality of your vision. Also, the process of selecting products is quite lengthy; their initial cost will also be an order of magnitude higher than that of soft lenses.

How to choose the right gas permeable lenses

In order to choose hard lenses wisely, you first need to consult a specialist. It determines visual acuity and the maximum degree of correction. Using special equipment, the ophthalmologist measures the necessary parameters of the patient’s cornea. What follows is trying on several pairs. All these manipulations are necessary for perfect lens fit. The production of hard contact lenses is carried out purely individually, taking into account more than 20 parameters of the eye. The engineer models the required design (optical zone, sliding zone, edge region). Next, the product is turned on a special machine in full accordance with the layout. The most famous manufacturer in this area is the German company Wohlk. This manufacturer ensures high quality products. As a rule, after 14 days you can receive a ready-made set of lenses.

Daily care of hard contact lenses

First of all, any lenses require proper personal hygiene. Hands should be washed with soap and water before removing or putting on. It is best to wipe them with a waffle towel to avoid getting various lint on the lens. Storage containers must be kept clean. For women there are special rules. Makeup should only be applied after the lens is in place. Accordingly, remove it after removing the product from the eye. A daily cleaner for hard gas permeable contact lenses is also necessary. With its help, dirt is removed, and deeper cleaning is carried out once a week. It is worth noting that you cannot rub the lenses too much, so as not to disturb the optical properties. Today, a multifunctional cleaner for hard contact lenses is widely used. It allows you to effectively remove protein deposits (for example, Boston Simplus solution) and does not require additional enzymatic purification. It also perfectly disinfects and softens contact lenses. Over time, the product becomes more difficult to clean. In this case, hard lenses can be polished in a special laboratory.

Special requirements for owners of hard lenses

Wearing hard lenses imposes certain responsibilities on the patient. Visits to the ophthalmologist should be regular. This will enable the specialist to assess the condition of the eyes. If there is the slightest change in the condition of the eyes, you should consult a specialist. Timely treatment will help avoid conditions such as corneal edema, microbial keratitis, conjunctivitis, corneal ulcer, allergic reactions. Rigid gas permeable contact lenses are an excellent solution for vision correction in many cases, but they require proper and careful care.

ZhGKL are manufactured strictly according to individual order, taking into account all the patient’s parameters, as they require a more accurate match inner surface corneal surface lenses.

Hard contact lenses

Modern hard contact The lenses are made from gas-permeable materials containing silicone, which makes them more flexible than previously existing gas-tight PMMA lenses, while also allowing large amounts of oxygen to pass through the lens to the cornea. This allows rigid gas permeable contact lenses to provide a significantly more comfortable and healthier wearing experience compared to their gas-permeable predecessors, which are no longer commonly prescribed.

Benefits of hard contact lenses

Compared to soft contact lenses, rigid gas permeable contact lenses provide significantly better vision because, due to their higher rigidity, they retain their shape during blinking and therefore the image remains stable at all times. Soft contact lenses crumple slightly when closing the eyelids, which leads to the fact that the picture seems to “float”.

With proper care, rigid gas permeable contact lenses can be worn for at least 1 year due to the fact that they are resistant to almost all types of deposits, since their surface is less porous and easier to clean than the surface of soft contact lenses. They are also more difficult to damage or tear than soft contact lenses.

Rigid contact lenses are made taking into account the individual parameters of the patient's cornea, so their shape is more congruent with the shape of the cornea, that is, it fits it perfectly. The mobility of a hard contact lens is 2-4 times greater than the mobility of a soft one. All this ensures a much better exchange of tear fluid in the sublens space and a much greater supply of oxygen to the cornea, and therefore a less frequent development of hypoxic (associated with a lack of oxygen) complications.

In addition, there are situations when soft contact lenses cannot be offered to the patient in principle and hard contact lenses are the only possible means of vision correction for such people.

Hard contact lenses for high degrees of myopia (nearsightedness) and hypermetropia (farsightedness)

The range of optical power (diopters) of most modern soft contact lenses does not exceed -12.00 D - +8.00 D. And the properties of the materials of those contact lenses that will provide high-quality vision at higher degrees of myopia and farsightedness ( up to 20.00 D), unfortunately, leave much to be desired, so wearing such soft contact lenses often leads to the development of complications. In addition, you need to understand that the higher the degree of myopia, the thicker the soft contact lens along the periphery, and the higher the degree of hyperopia, the thicker it is in the center, which, taking into account the tighter fit compared to hard contact lenses again leads to the development of hypoxic (associated with a lack of oxygen supply through a thick lens) complications when wearing soft contact lenses.
What can these unfortunate people do? Either be content with incomplete, insufficient correction, depriving yourself of the opportunity to see well and enjoy a full life, or use soft contact lenses, wearing which will almost inevitably lead to the development of complications. They, of course, can be offered spectacle correction, but in glasses with such diopters, peripheral aberrations (distortions) will be very pronounced, which will make their use very uncomfortable, and their aesthetic properties will be very questionable ( spectacle lenses will be thick, and the eyes behind them will be either very large with high degrees of farsightedness, or very small with myopia).
But in reality there is a choice! Rigid contact lenses tend to have a wider refractive range ( -25.00 D to +25.00 D), and due to the use of materials with high coefficient refractions remain quite thin even at large diopters. In addition, due to better exchange of tear fluid in the sublens space, they ensure adequate oxygen supply to the cornea.

Rigid contact lenses for high astigmatism

The optical power of the cylinder of most toric soft contact lenses does not exceed 2.25 D, some of them have restrictions on the axes of the cylinder, which in some cases makes it impossible to provide high-quality vision to patients who need it.
Rigid contact lenses, due to a fundamentally different system for correcting astigmatism, make it possible to cope with this problem.

Hard contact lenses for presbyopia (age-related farsightedness)

To correct vision in patients over 40 years of age, in addition to glasses, special multifocal soft contact lenses can be used. But all multifocals presented on the domestic market soft lenses have restrictions on optical power for distance ( -10.00 D to +6.00 D) and cannot be offered to patients with astigmatism, since toric multifocal soft contacts are not represented in our country in principle.
Hard contact lenses do not have such restrictions: they can be selected for patients over 40 years of age, both with high degrees of farsightedness and myopia, and for those who have astigmatism.

Selection of hard contact lenses

So what exactly is selection of hard contact lenses?
This procedure is carried out on the basis of examination data using an autorefractometer and visometry. After these studies are completed, lenses from a diagnostic kit are installed on the patient’s eyes, the “fit” of which is assessed after 20 minutes by a doctor during a slit-lamp examination and fluorescein staining. The visual acuity obtained with hard contact lenses is also checked. As a rule, in most cases, successful fitting requires trying on 1 to 3 diagnostic hard contact lenses in each eye. This is necessary in order to achieve complete perfect compliance of the shape of the inner surface of the hard contact lens with the surface of the cornea, and thereby ensure its correct centering, sufficient mobility and, as a result, ensure comfortable and healthy wearing.

After completing all the described procedures, having decided on the parameters of the hard contact lenses the patient needs, we can send an order for their individual production.

Manufacturing of hard contact lenses

Wanting to offer our patients the best, we cooperate with the German company Wöhlk, which has 60 years of experience production of hard premium contact lenses. The level of this company is evidenced by the fact that such an optical giant with a worldwide reputation and excellent reputation as Carl Zeiss entrusted it with the production of its soft contact lenses. The Wöhlk plant is located in northern Germany in the town of Schenkirchen, and every product produced there is subject to the most stringent controls and has a guarantee of the highest quality. All orders for hard contact lenses are manufactured using high-precision equipment according to the individual parameters of each individual patient. The waiting time for such an order, including delivery from Germany, is usually 14 working days.

Training and dynamic observation

If you want to wear hard contact lenses, it is important to understand that they not only provide high quality vision, but also impose significant responsibility. Wearing such lenses requires more frequent visits ophthalmologist for dynamic assessment of eye condition than when using glasses and soft contact lenses. Yes, and lenses require certain procedures when caring for them. An important factor in the safety of wearing them is compliance with hygiene rules, including when putting them on and taking them off.
That is why in our vision correction offices final stage When dispensing hard contact lenses, we inform our patients in detail about how to wear and care for them correctly.
An indispensable condition is to purchase a starter kit, which includes a set of all necessary funds and accessories for the first time.
When purchasing a starter kit patient education independent skills of putting on and removing hard contact lenses, if they are choosing lenses for the first time, as well as dynamic observation by an ophthalmologist during the entire period of wearing the lenses, for free.
