Laser adjustment recovers view, however does not match everybody

WHO stats are as follows: over the previous 10 years around 5 million laser sight correction procedures have actually been performed in the world. More than 20,000 operations are performed each year in Russia. Guaranteed fully restore the vision of 90% of people.

The possibility of problems after surgery is not greater than 0.5%, which is really irrelevant for medical treatment. Nonetheless, worries and also myths worrying laser adjustment, in spite of positive data, live as well as passed from mouth to mouth. How safe and also reliable this operation, the correspondent of SE identified.

Laser vision adjustment essentially alters the curvature of the cornea with the assistance of a laser beam of light. These are operations such as PRK (photorefractive keratectomy) and also LASIK (laser keratomileusis). When performing PRK (used for a small level of disturbance), parts of the corneal tissue are removed with the help of an ultraviolet laser. The LASIK procedure is done making use of an added microkeratome gadget, which enables a thin cut of the surface layers of the cornea.

The laser vaporizes the deep layers of the cornea to a defined depth, and the removed shutoff after that returns to its initial setting. So the surface area of the cornea stays unblemished, so the LASIK operation is less painful, as well as the impact is observed almost promptly after leaving the operating space.

You can, you require as well as

you can not Similar to any kind of medical intervention, excimer laser improvement has signs and contraindications. The department of refractive laser surgery of the Novosibirsk branch of the ISTC «Eye Microsurgery» Lyudmila Yakovlevna Lautkina divulged the information.

Excimer laser improvement is advised for:

— near-sightedness up to -15.0 D, farsightedness up to + 4.0 D, astigmatism as much as ± 3.0 D,
— astigmatism after previous operations— keratotomy, thermokeratocoagulation, after cataract removal.

Barrel of honey

What is the advantage of excimer laser vision improvement, what encourages individuals to do it? Lyudmila Yakovlevna (NMTC «Eye Microsurgery») describes the pros. First, the exact estimation of the operation for each and every client, depending upon the individual features of the structure of the eye, practically eliminates the possibility of mistake. Secondly, the rate of the operation is 5-7 mins.

Thirdly, painlessness— the operation is done under neighborhood anesthetic, and also after it passes through, no pain experiences are observed.

Fourth, fast recovery— in a week it is already possible to return to work, and also the effect ends up being visible a couple of hours after leaving the operating space.

A spoon of tar

Nevertheless, not whatever is so glowing. There are downsides. «The negative aspects are instead unusual,» continues Lautmila Lautkina.— Three months not to bathe in the bathroom, do not swim in the pool, do not raise weights more than 10 kg.» In addition, within half a year the individual must be observed in the clinic as well as comply with the prescriptions of the doctor: execute acrobatics for the eyes, utilize declines, equilibrium with the computer system and TV. When all the directions for the occurrence of regression— a decrease in vision— are not observed. Sometimes, there are doubts about the requirement for laser modification in eye doctors who are not engaged in this task:

«I’m not versus laser correction. I think that this is a wonderful way to fix sight,— claims Marina R. Golikova, an eye doctor of the clinical facility «Catharsis». «However, I do not believe that surgical treatment is required for a small minus— you can do without surgical treatment.»

With regard to unsuccessful operations, the doctor Lautkina assures that they almost do not take place: «If there is a regress, after that it is primarily a consequence of not a surgical operation, however of other diseases. With the assistance of medical actions, the defect is gotten rid of. » The clinic «Excimer» is warned regarding the opportunity of pre-correction. It is carried out in those cases when, in spite of the recovery procedures, after the procedure, vision falls. This happens with a noticable— listed below -10.0 D— myopia, and this person is warned prior to the operation. Do pre-correction for free.

Women question

After the excimer laser improvement, there are no injuries and stitches on the eyes, they do not end up being much more prone. In a year after the procedure it is rather feasible to provide birth without Caesarean section. Nonetheless, prior to this it is needed to speak with at the eye doctor. Throughout the pregnancy as well as feeding operation is not brought out: since of hormonal change in the body of a woman’s vision is unstable, the magnitude of myopia or hyperopia can alter, occasionally significantly.

Individual experience

The correspondent of SE made a laser adjustment 6 months ago. For a begin, I undertook a full analysis exam— they inform me what happens to the eyes, whether surgical procedure is essential or what. After the shipment of the typical collection of tests, the date of the procedure is appointed. Normally it goes for 2 days— one eye each day. If on the very first day I did not desert the soothing pill offered by the registered nurse at the door to the operating space, then the second one entered into it boldly— the procedure is completely intrepid and truly pain-free.

From unusual feelings, I would certainly highlight a solid blinding light, the smell of scorched and also the moment when you see how your cornea is smoothed with a brush.

Already an hour after the operation, I had the ability to clearly see the faces of others. A day later on, she flaunted herself by checking out signboards. A month later, regression started. It had to do with the pre-correction, but after energetic acrobatics for the decreases, vitamins as well as eyes, the vision maintained. Glasses and a container for lenses left a memory. Without them, certainly, it is more convenient.
