Cataract is a disease associated with clouding the lens of the eye. Not so long ago, such a diagnosis for the elderly sounded like a verdict. This is a very insidious disease, which develops slowly. Usually people do not even immediately notice the presence of such a disease. As a result, the visit to the doctor is belated.
But a professional ophthalmologist could have discovered cataracts in the early stages, eliminating the trouble. This disease is one of the most common in the eye area. And according to the number of rumors and myths, cataracts are not equal. However, it is worth to learn the real truth.
Cataracts are not a serious disease.
This is a very dangerous myth, because cataracts are a serious eye disease, which most often affects people in old age. The lens is a natural lens, transparent and elastic. It can change its shape and focus very quickly, which makes it possible to see well both in the distance and in the distance. And because of the turbidity in the eye falls only a small part of the world, as a result, people see blurry and indistinct. Especially it becomes clear in bright light. The disease progresses over the years, the area of turbidity increases, vision becomes worse. In the advanced form of cataract, the swollen lens begins to occupy more and more of the anterior chamber of the eye, preventing the outflow of intraocular fluid. This increases the pressure inside the eye and leads to the development of glaucoma. The risk is also great because, without treatment, vision can generally disappear irretrievably.
Cataracts appear in older people, young people do not.
Most often this problem is really an age. It is directly related to aging of the body. However, cataracts can appear at any age, even in children. Fortunately, this happens rarely, in only five cases per 100,000 newborns. Cataracts without age-related can appear as a result of somatic diseases. It can be diabetes or physical impact on the eye – trauma, solar radiation.
Cataract development can be prevented.
Prevention is available only for the most complex forms of cataracts that appear as a result of any diseases. In this situation, the best thing that can and should be done is to cure the most provocative deviation and control the blood sugar level. But to prevent the development of age-related cataract, which is often also hereditary, is almost impossible.
Cataract can be defeated with drops.
Those numerous attempts to create drops that would have fought with the opacities of the lens have failed. It is believed that they can sometimes slow down the development of cataracts, but this does not solve the cardinal problem. That is why the main way to treat the disease is an operation to remove the clouded lens. It is changed to a new, artificial, created from special polymers. To date, this is a proven operation that is carried out in many clinics. With a successful outcome, it allows you to quickly restore the quality of life. For 1-3 days after surgery, visual rehabilitation will take place, and physical limitations will last for a maximum of 2-3 weeks.
Before you remove the cataract, you must wait until it ripens.
This is a fairly common statement that doctors constantly face. Once this approach was justified – technical capabilities allowed to work qualitatively only with ripe cataracts. However, today the situation is different. Experts believe that the question of surgical intervention should be approached individually. It is important to consider what the patient feels. If a person works, then his vision should be high, without going below 70-80%. But for an elderly person, the bar can drop to 30-40%.
After removing cataracts, glasses will no longer be needed.
The new lens has solved the problems of light refraction and light transmission.However, there remains the question of accommodation, that is, a clear vision of objects located at different distances from the glasses. This problem is usually solved by prescribing extra glasses to the patient. Recently, multifocal artificial lenses have become available that can provide high-quality vision both in the vicinity and in the distance.
Cataract can be defeated with the help of traditional medicine.
There is an opinion that by some grandmother’s methods one can overcome cataracts. In fact, in nature there are no such drugs that would be able to restore the transparency of the lens. Its turbidity is the result of an irreversible process associated with the contained proteins. And neither diet, nor massage, nor folk medicine will help here. So the operation can not be avoided anywhere.
The cataract surgery is very long.
Today, ophthalmologists can perform such a quick and painless operation as phacoemulsification. Implantation of an artificial lens will take about 15 minutes. This operation is performed under local anesthesia, the patient himself does not experience any inconvenience. First, the diamond tool surgeon will make a small incision, up to 3 millimeters in length. Even through this tiny hole, further manipulations will occur. A special ultrasound probe will turn the lens into an emulsion, which will be removed from the eye. And in the empty capsule will be inserted a folded flexible liznu, which independently turns and fixes. It should be noted that such interference will cost without suturing – the micro-cut is self-sealing.
After the operation to remove cataracts, you will have to lie in the hospital for a long time.
Today, this operation is increasingly performed on an outpatient basis. Without any hospitalization, the patient returns home after her. At the same time, there are almost no restrictions on physical activity, recovery takes place without pain. But this became possible with the advent of phacoemulsification. This technique and allowed to achieve good results.
Cataract is just a film on the eye.
Actually, it’s about the opacity of the lens, located inside the eye. Ideally, this place should be transparent to let in light. And with cataract vision is covered with fog, objects become dull and blurred. Other symptoms of cataracts are bifurcation, image distortion, reduced clarity, the appearance of yellow shades. The patient can often change glasses or contact lenses, trying to choose a better option.
Cataracts are removed with a laser.
Many people, especially the elderly, do not remember the word ultrasound, it is much easier for them to think about a laser. Perhaps the word itself is associated with something progressive and modern. In fact, the old lens is crushed by ultrasound. However, after some time already behind the artificial lens can appear already and a film – a secondary cataract. That’s it, and you can remove the laser in 5 minutes.
You can remove the cataract itself, without changing the lens itself.
Of course, you can do it, but you just have to wear heavy glasses with thick glass, which will replace the lens. Such operations remained in the past, with the modern level of surgery you can give your eyes a qualitative artificial lens with calculated optical power. In the eye, this element of biocompatible material will feel like a native.
Artificial lenses among themselves are no different.
There are many varieties of this optical instrument from different manufacturers. They differ both in their properties and in their cost. If the decision on the operation is accepted, then the optical power of the lens should be calculated further. After this calculation, the ophthalmologist will already recommend that lens, which best meets the needs of the eye. It is important to remember that the patient should get a passport of his lens in his hands to be sure that he was implanted precisely.
After the operation on the cataract, the eye can still see badly.
It happens so, only rumors should be separated from the truth. First of all, what condition of the eye was before the operation? Perhaps there was a pathology of the retina or optic nerve, then such a result is expected. In any case, before the operation of the patient, they will be warned about a possible outcome, will give a forecast. And what should the doctor do if the person insists on the operation anyway? Whatever it was, the vision that was lost directly due to cataracts will be returned.
The cost of surgery with ultrasound can vary considerably.
The operation itself is not only ultrasonic, but also seamless. It can not be cheap. After all, one-time and high-quality foreign materials are used, and the device, an ultrasound phacoemulsifier, is worthless money. Speaking of cheap ultrasound surgery, in mind can have tunnel extraction. It really costs much less, but the lens is removed mechanically, while overlapping the seams. So doctors can, under the banner of new technology, offer obsolete and cheaper, which is a fraud.
The most reliable thing to do is surgery in famous clinics.
Yes, in those clinics that are on hearing, maybe the equipment will be up-to-date, and the walls are repaired. However, this does not guarantee the final result. The main thing here is the specialist who will be given sight. After all, in inept hands, any apparatus will become only a piece of iron. So, referring to the doctor, it is worth asking him about the experience, about the specialization, and about the number of operations performed.
Cataracts may appear due to excessive eye strain.
In fact, cataract does not develop from the hard work of the organs of sight – reading, sewing, watching TV.
Cataract is infectious.
This disease is not transmitted by known methods, however, there is a genetic predisposition.
Cataracts are painful and result in blindness.
This disease is so slow that a person often does not notice it. For the majority this is a common disease associated with old age. But blindness can come only if not treated. Recently, progress has made possible operations that allow you to fully restore your eyesight.
Cataracts can arise again.
Relapses are not possible in this case. After a cataract appears because of changes in the lens, and after the operation it becomes artificial, with absolutely different properties. So most patients gain clear vision.
