The clouding of the lens. Correct this condition is possible only with surgical intervention. The disease is called cataract. Prices for the operation depend on the type of intraocular lens, ranging from 1.5 to 70 thousand rubles.
The patient is usually offered several types of lenses. How to choose it and which is better? Lenses of domestic manufacturers are set free of charge, guaranteeing good performance of the visual organ. Is it really? Imported analogues have to be taken for a lot of money.
Choice of intraocular lenses
Let us consider in more detail information about cataract disease: operation, reviews. Which lens is better? According to hospital patients, a cheap lens is harder to install. Surgeons make a larger incision to insert it. Service life is much less than imported analogues. Consider whether this is so.
Distinguish the quality of imported lenses, delivered from the USA, Europe, and Asian products. It includes goods from India. There is a risk of astigmatism after surgery, but when using a poor-quality lens, it is much higher.
The difference lies in the installation method and the form of the lens itself. Imported products are soft and easy to bend. A very small hole is required to install it.
Comparison of requirements for glasses and lenses
The action of the intraocular lens is comparable to the work of glasses. But there are some differences:
- Glasses are worn before the eyes. Lenses are installed inside the visual organ.
- The former correct vision, the latter correct it completely.
- Glasses are easy to replace and rarely have consequences if used improperly.
- Installation of lenses is a complex surgical microoperation requiring high qualifications, experience and sophisticated equipment. Before cataract treatment, an appropriate examination is performed.
An artificial lens with cataracts is selected on the basis that its materials will be chemically neutral to the internal environment of the eye. It is important that over the years its partial destruction or deformation does not occur.
Types of intraocular lenses
Each lens is selected individually. There have been cases when different lenses are placed on both eyes. The ophthalmic clinic offers customers 2 types of lenses:
- Monofocal. Imitation of the work of the natural lens. But there is one feature - farsightedness is restored, but they wear glasses for reading.
- Multifocal. They allow you to clearly distinguish objects not only in the distance, but also in the vicinity. Full eye work is provided.
For some diseases, a specially made lens is required. The name of such lenses is toric. They are used for astigmatism, when operations and the selection of glasses will not bring success.
Materials for intraocular lens
Domestic lenses have been used since 1967 in eye microsurgery. They are made of specially developed material - bioinert plastic. There are no consequences after installation, it is not torn away by body tissues. The size of the notch is not more than 3 mm. A more flexible structure allows you to roll the lens during the operation.
Intraocular lenses can have a filter that is selective to ultraviolet light, thereby protecting the eyes from the harmful part of sunlight. Blue rays are dangerous for the retina, the natural lens has the ability to delay them. To preserve these properties, an appropriate filter was added to the artificial model. The lens was painted yellow.
Types of materials:
- acrylic;
- hydrogel;
- silicone;
- collamer.
Cost of surgery
The pricing policy in the clinic is built personally for each client. How much does a lens replacement cost, depends on the following circumstances:
- the complexity of the operation;
- level of service: comfort, additional services;
- type of lens and supplies;
- anesthetist services;
- periodic examinations after surgery.
The state ophthalmological clinic does not have all the possibilities of a private organization. Experiencing enormous competition, they use all the ways to improve the level of service. This is a periodic training of specialists, purchase of the latest versions of medical equipment, strict adherence to instructions.
The client will be much more comfortable without huge lines and nervousness. Friendly staff will help to solve all the difficulties encountered before preparing for the operation. He will hold consultations on the topics: "Cataract disease", "Operation", "Reviews", "Which lens is better?" He will inform the patient how to avoid the consequences after surgery.
Recent developments of Western colleagues allow an incision of not more than 1.5 mm. Superplastic lens will have a relatively low cost and will soon appear in domestic clinics. The healing time with such a lens is minimal after surgery. Cataracts are no longer a serious problem with the current level of development of medicine.
The consequences of installing an artificial lens
Having studied all the problems of cataract disease (surgery, reviews, which lens is better), doctors came to the conclusion: a poor-quality artificial lens is the main negative consequence after installation. In the first years of use, it will not be possible to notice the difference. With good geometry and refractive characteristics, poor-quality material may begin to deform due to:
- low margin of safety, with high elasticity;
- blurred focus area.
The lens does not stand still, it experiences a constant load, changing its bulge. This occurs when looking into the distance or reading the text very closely. Any material has a margin of safety. Import manufacturers produce lifelong lenses.
Lens Replacement Procedure
Before the operation, it is necessary to undergo an examination and pass tests:
- standard set: blood, urine;
- electrocardiogram;
- chest x-ray;
- collect information about the diseases from the therapist;
- visit the dentist and otolaryngologist.
Analyzes are valid for no more than a month. During surgery, local anesthesia is performed. The operated person hears and feels everything without pain. He must be relaxed and follow the instructions of the surgeon. You may need to look up or sideways.
To enter the instrument, make punctures, through the opened shell the lens is removed. The old bag is being cleaned. The artificial lens is refilled through a puncture and straightened inside. This completes the procedure, washing the eye with a solution.
A patient is observed in a hospital for 2 days. It will take several visits to analyze the condition after surgery. Full recovery will occur after a month.
Duration of restoration of visual acuity
The recovery period takes no more than one and a half months. 3 hours after surgery, excellent vision is observed, the replacement of the lens usually takes no more than a few minutes. Difficulties due to the individual characteristics of the patient can extend the procedure up to 2 hours.
After the operation, the patient uses drops throughout the recovery period. These measures serve to prevent possible inflammation. It is not recommended to perform strength exercises, it is necessary to exclude stress, you can not touch your eyes once again with your hands. Exclude sauna visits, bathing and avoid dusty places. Cosmetics around the eyes also fall under the ban.
The conducted customer survey is based on completed questionnaires. They included frequent questions on such points: cataract disease, surgery, reviews, which lens is better. The opinion of visitors who came to the consultation is ambiguous: some single out more expensive lenses of European production and would not save on a responsible body. The second ones are inclined to consider: there is no difference between the lenses of Indian production, Russian and European.
According to most visitors, Indian lenses are questionable in their quality, confidence in a more expensive product prevails. There were supporters of the Russian product, conclusions were drawn on the number of complications. Familiar patients passed without problems with such lenses for more than 10 years.
