Cataract surgery: reviews, which lens is better? Ophthalmic Clinic

Cataract. To correct this condition is possible only with surgical intervention. The disease is called cataract. Prices for surgery depend on the type of intraocular lens, ranging from 1.5 to 70 thousand rubles.

The patient is usually offered several kinds of lenses. How to choose it and which one is better? Lenses of domestic manufacturers put free of charge, guaranteeing good work of the visual body. Is it really? Imported analogues have to be borrowed for a lot of money.

Problems of choice intraocular lenses

Let's consider the details of the cataract disease: operation, reviews. Which lens is better? According to the patients of the hospital, a cheap lens is more difficult to install. Surgeons make a larger incision to insert it. The service life is much less than imported analogues. Let's consider, whether so it.

Distinguish the quality of imported lenses, supplied from the USA, Europe, and Asian products. It includes goods from India. There is a risk of astigmatism after surgery, but when using a low-quality lens it is much higher.

The difference lies in the method of installation and the appearance of the lens itself. Imported products are soft and easily bends. To install it requires a very small hole.

Comparison of requirements for glasses and lenses

The action of the intraocular lens is comparable to that of glasses. But there are some differences:

• Glasses are worn before the eyes. Lenses are installed inside the optic.
• The first correct vision, the second correct it completely.
• The glasses are easy to replace and rarely have consequences if used incorrectly.
• The installation of lenses is a complicated surgical micro-operation, requiring high qualification, experience and complex equipment. Before the treatment of cataracts, an appropriate examination is carried out.

The artificial lens for cataracts is chosen on the basis that its materials will be chemically neutral to the internal environment of the eye. It is important that in the course of time, its partial destruction or deformation does not occur.

Types of intraocular lenses

Each lens is selected individually. There are cases when different lenses are placed on both eyes. The ophthalmic clinic offers clients two types of lenses:

• Monofocal. Simulation of the natural lens. But there is one peculiarity - hyperopia is restored, but glasses are put on for reading.
• Multifocal. They allow you to clearly distinguish objects not only in the distance, but also near. Full-value eye work is provided.

For certain diseases, a specially manufactured lens is required. The name of such lenses is toric. They are used for astigmatism, when operations and selection of glasses will not be successful.

Materials for intraocular lens

Domestic lenses have been used since 1967 in microsurgery of the eye. Produced from a specially developed material - bioinert plastic. There are no consequences after installation, it is not rejected by the tissues of the body. The dimensions of the notch are not more than 3 mm. More flexible structure allows you to fold the lens during the operation.

Intraocular lenses can have a filter that is selective to ultraviolet, thus protecting the eyes from the harmful part of sunlight. For the retina of the eye, blue rays are dangerous, 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 colored yellow.

Types of materials:

• acrylic;
• Hydrogel;
• Silicone;
• Collamer.

Cost of surgical intervention

Pricing policy in the clinic is built personally for each client. How much does a lens replacement cost, depends on the following circumstances:

• Complexity of the operation;
• Level of service: comfort, additional services;
• Type of lens and consumables;
• Anesthetist services;
• Periodic examinations after surgery.

The state ophthalmologic clinic does not have all the possibilities of a private organization. Experiencing huge competition, use all the ways to improve the level of service. This is the periodic training of specialists, the purchase of the latest versions of medical equipment, the strict adherence to instructions.

The client will be much more comfortable without huge queues and nervousness. Friendly staff will help solve all the difficulties that arise before preparing for the operation. Will hold consultations on the topics: "Cataract Disease", "Operation", "Reviews", "Which lens is better?" He will inform the patient how to avoid consequences after surgery.

The latest developments of Western colleagues allow cutting 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 the operation. Cataract is no longer a serious problem with the current level of development of medicine.

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 can begin to deform due to:

• Low safety factor, with high elasticity;
• Clouding the focus area.

The lens does not stand still, experiences a constant load, changing its bulge. This happens when you look into the distance or a very close reading of the text. Any material has a margin of safety. Imported manufacturers produce lenses designed for life.

The procedure for replacing the lens

Before the operation it is necessary to pass the examination and take the tests:

• Standard set: blood, urine;
• electrocardiogram;
• Chest x-ray;
• Collect information about the therapist's illnesses;
• Visit a dentist and an otolaryngologist.

The tests are valid for no more than a month. During the operation, a local anesthetic is performed. The operator hears everything and feels without pain. He should be relaxed and perform the surgeon's commands. You may need to look with your eye 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 spreads inside. This is the end of the procedure, washing the eye with a solution.

There is a patient in the hospital for 2 days. It will take several visits to analyze the condition after the operation. A full recovery will take place a month later.

Duration of recovery of visual acuity

The recovery period takes no more than one and a half months. After 3 hours after the operation, excellent vision is observed, the lens replacement usually takes no more than a few minutes. The resulting difficulties due to the individual characteristics of the patient can extend the procedure to 2 hours.

After surgery, the patient uses drops throughout the recovery period. These measures serve to prevent possible inflammation. It is not recommended to perform strength exercises, you need to eliminate stress, you can not touch your eyes again with your hands. Exclude visiting the sauna, bathing and avoiding dusty places. Also under the ban is cosmetics around the eyes.

The customer survey is based on completed questionnaires. They included frequent questions on such items: cataract disease, surgery, reviews, which lens is best. The opinion of visitors who came to the consultation is ambiguous: some allocate more expensive lenses of European manufacture and save on the responsible body would not. The second is inclined to consider: the difference between the lenses of Indian production, Russian and European does not exist.

According to most visitors, Indian lenses are questionable in their quality, confidence in a more expensive product prevails. There were supporters of the Russian goods, conclusions were made on the number of complications. Familiar patients passed without problems with such lenses for more than 10 years.
