It is good to see the surrounding objects, to fully enjoy the beauty of the world and its diversity – the normal desire of any person. Contact lenses and glasses compensate for poor vision, but they cause some discomfort, they are not always comfortable to wear, and they can also be lost or damaged. Therefore, people often resort to laser vision correction to solve this problem once and for all. One of the most popular laser surgeries is LASIK eye surgery.
With this method, the shape of the cornea is corrected by transferring its layers. To access the upper layer of the cornea, it is not completely cut, but carefully taken to the side. It turns out a kind of “lid”, which, upon completion of the procedure, returns to its place. Incision of the body mass with a contact fiber – microkeratome. It happens like this: the patient asks for 10-15 seconds to look at the flashing green light, which is located in the laser unit. At this time, the laser starts to work. A person at this time may feel touch and briefly lose the green light from their field of vision.
How to prepare for this operation:
7 days before the operation, you need to stop wearing soft contact lenses, hard – a month before. On the day of surgery, you do not need to use cosmetics, including cream and aftershave lotion.
You can eat and drink as usual, because during the operation, not anesthesia is used, but local anesthesia.
Before the operation, the patient must be re-examined by the doctor to make sure that he is in perfect health. With a residual runny nose and cough, you will not be let through.
How does LASIK surgery begin?
Preparatory stage for each patient
The LASIK surgeon, together with the patient, measures his data and pronounces the algorithm of actions.
During the operation itself, the surgeon will speak his every step, which will help the patient reduce nervousness. Precise laser treatment requires the patient to respond with the eyes, so the operation is not performed under general anesthesia.
An anesthetic is instilled into the eyes. That is, the sensitivity disappears, the sensation of touching the eye may remain. It really isn’t that big of a deal, especially for those with experience wearing contact lenses.
The eyelid appendage is disinfected with the necessary solution. Around the eyes, the surgeon imposes a dense napkin. An eyelid speculum is inserted into the eye.
Usually, the operation is carried out quickly so that the patient does not have time to start to worry and thereby interfere with the doctors.
The next step is to prepare the cornea before the laser.
Then comes the correction.
During the laser vision correction itself, there are no problems, only the noise of the laser and, possibly, the smell of the skin are heard.
LASIK ends with the corneal flap being put back in place and gently spread out. No stitches are required – due to the natural stickiness of the corneal tissues, they are tightly pressed and the wound is actually insignificant.
The eye is washed with a solution. At this point, the patient may feel cold in the eye area.
Full recovery will occur within two weeks, but immediately after the completion of the operation, it becomes noticeable how visual acuity has increased. On the first day after surgery, it is best to keep your eyes closed. Because at first they will be very sensitive.
On average, the price of laser surgery starts from 1000 to 4000 per eye.
This large difference is due to various factors:
1) Location of the clinic. In some areas, the cost of living is higher than in others, so medical procedures are more expensive.
2) Costs for a doctor. If the doctor has the equipment, then the price of treatment may be less than when renting equipment, as the doctor needs to make his work more profitable.
3) The price of the operation is also affected by the experience of the doctor or in which center he works. If, due to his reputation, the doctor is in demand, then naturally the cost of his work will be higher.
But it is important to understand that the cost of the operation does not depend on how bad your eyesight is. An exception is the presence of a form of myopia or farsightedness, for the treatment of which other types of eye operations are necessary.
Who should not have LASIK
Despite the presence of a large number of pluses and positive reviews, this method is not suitable for everyone. You can not do Lasik to persons under 18 years of age, since the procedure is designed for a mature eye, otherwise it will be difficult to guarantee the result. Absolute contraindications include:
1) progressive myopia;
4) retinal detachment and a number of retinal diseases;
5) inflammatory eye diseases;
6) corneal pathology and other eye diseases.
Of the common diseases, LASIK eye surgery is contraindicated in diabetes mellitus, rheumatism, skin and connective tissue diseases, neurological diseases and diseases during the feeding period, thyroid diseases, oncological diseases, AIDS, etc.
But if you do not have any of the diseases, then you can safely do vision correction.
Are complications possible?
For an experienced surgeon, the number of complications during surgery is reduced to 0.1-0.2%. In the postoperative period, complications associated with the exclusion of residual myopia or farsightedness are possible. In this case, re-correction is carried out 2-3 months after the first operation. Healing problems are much less common. All of these postoperative problems respond well to treatment and occur in 0.2-0.3% of cases.
If you are concerned about complications, then you can make a custom LASIK. What is it?
This type of eye surgery involves unique laser procedures that are based solely on the characteristics of your eyes. In individual LASIK, the eye is measured from front to back with a special laser using “wavefront” technology to create a three-dimensional (3-D) image of the eye. The data contained in the wavefront map will help the laser to tailor an individual treatment.
This technology is revolutionary in the field of eye surgery, as it allows you to change not only visual acuity, but also its quality, i.e. visual perception. This can lead to a reduced risk of side effects after LASIK, such as problems with night vision, etc. With this type of treatment, the chance of complications is reduced, since all processes are based on your characteristics.
Thus, we can conclude that LASIK is the most frequently performed vision correction surgery. Most often it is carried out for the treatment of myopia, but it also helps with astigmatism. This is the most “sparing” and effective method that preserves the anatomy of the layers of the cornea. Most importantly, after the LASIK Surgery operation, you will forever put aside annoying glasses and lenses, acquiring absolutely normal vision.
