Cataract surgery: reviews, which lens is better? Ophthalmic Clinic
Lens clouding. 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 organ. Is it really? Imported analogues have to be borrowed for a lot of money.
Problems of selection of 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. Terms of service are much lower 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 the requirements for glasses and lenses
The action of the intraocular lens is comparable to that of glasses. But there are some differences:
- The 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.
- Lens installation 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. Ophthalmologic clinic offers clients 2 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. A full-fledged eye operation 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 bring success.
Materials for intraocular lenses
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. A 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 harmful parts of sunlight. For the retina of the eye, blue rays are dangerous, the natural lens has the ability to hold them. To save these properties, an appropriate filter was added to the artificial model. The lens was colored yellow.
Kinds of materials:
Cost of surgical intervention
Price policy in the clinic is built personally for each client. How much does the lens replacement cost, depends on the following circumstances:
- the complexity of the operation;
- level of service: comfort, additional services;
- type of lens and consumables;
- anesthetist services;
- periodic inspection after surgery.
The State Ophthalmic Clinic does not have all the capabilities 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.
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.
Recent 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 installation of 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.
Procedure for replacing the lens
Before the operation it is necessary to pass the examination and pass the tests:
- standard set: blood, urine;
- chest X-ray;
- collect information about the therapist's illness;
- visit a dentist and an otolaryngologist.
Assays 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 a tool, punctures are made, the lens is removed through the opened shell. The old bag is being cleaned. The artificial lens is refilled through the puncture and spreads inside. This is the end of the procedure, washing the eye with a solution.
A patient is observed in the hospital for 2 days. It will take several visits to analyze the condition after surgery. 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.
Customer surveys are based on completed questionnaires. They included frequent questions on such items: cataract disease, surgery, reviews, which lens is better. 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, the conclusions were made by the number of complications. Familiar patients underwent no problems with such lenses for more than 10 years.
