Laser keratomilez or Lasik - an effective method of vision correction

Eyes are not only a mirror of the soul, but also the main channel through which a person receives information about the surrounding world. Problems with vision, unfortunately, are not uncommon, but they can be solved. One of the most popular methods of correction of myopia, hyperopia, treatment of astigmatism is Lasik. Laser keratomileus (another name for the operation) combines microsurgical effects on the cornea of ​​the eye and excimer laser techniques. The ophthalmologist creates a new, optimal form of the cornea (it acts as a natural lens). As a result, the rays begin to focus on the retina, and the image becomes clear.

What it is

Lasik (other names of the technique LASIK, Lasik, Leysik) - this is the most common method of laser vision correction. The full name of the operation sounds like Laser Assisted In Situ Keratomileusis, it was suggested by Pallikaris (the famous Greek physician) in 1990. At the moment, Lasik is the safest, high-tech, time-proved laser correction technique.

Its effectiveness has been proven in numerous operations that can restore visual acuity and achieve stable results. The laser can be used to treat hyperopia, myopia and astigmatism.

Lasik is a great way to get rid of glasses and contact lenses. Rehabilitation is easy.

Features of the procedure

The popularity of the technique is simply explained - in fact it has a number of advantages over other refractive interventions. Let's name the main:

1. Lack of pain.
2. Quick recovery.
3. The minimum time of the operation.
4. Stable indicators of improving the quality of vision.
5. Absence of scars and stitches.

The essence of LASIK is the use of the UV beam of an excimer laser, which has a "cold" spectrum. This beam and allows you to change the optical power of the cornea, achieving precise focusing of light rays on the retina.With astigmatism, the cornea is given a spherical shape, with hyperopia "steep and with myopia - more flat.

The latest modification of the technique is Super LASIK. It takes into account the individual features of the structure of the cornea of ​​the patient's eye 100%.

Super LASIK is the latest modification of the laser vision correction technique under consideration, which is also called personalized.Such operations are carried out using a corneotopograph - a special device that scans the cornea thousands of different points (this is necessary to create an accurate map of the corneal surface and determine its refractive force).

Preparation of the patient

Have you firmly decided to get rid of contact lenses and glasses, returning to yourself the joy of seeing the world around? To start, select a clinic that performs LASIK operations, and then a doctor. Some patients "go" to the clinic, others to a certain specialist.

Looking for a doctor or clinic for laser correction Lasik? As you prefer - you can go to a medical institution, and a specific specialist.

Then the ophthalmologist, from whom you plan to be operated, should conduct a thorough comprehensive diagnosis - checking the patient's health, his eyes.Deep diagnosis is needed to exclude the presence of contraindications and make up an individual correction program.The predicted outcome of the intervention will be called by the doctor at the planning stage of the operation. If it turns out that the Lasik technique is not right for you, the doctor will suggest alternatives - for example, Epi-Lasik, Lasek, PRK or implantation of phakic lenses.

Diagnosis before surgery in front of eyes Lasik is mandatory - it must exclude the presence of contraindications.

After LASIK, many patients complain of dry eye syndrome. To prevent it from appearing, the doctor may prescribe to you the use of special eye drops.

The phased process of

Let's consider the process of the operation in stages:

1. The doctor instills the patient with anesthetic drops (general anesthesia, injections of anesthetic do not).
2. When anesthesia begins to act, the eyelid extends.
3. The surgeon will ask you to look at the point in the device (it glows) - this is necessary to center the position of the eye.
4. With the application of microkeratome, the doctor will begin to create a flap of the upper layers of the corneal tissue, then bend it, opening the laser beam access to the deep layers of the cornea.
5. The laser beam will evaporate part of the cornea and form a new (correct) surface.
6. The flap will be returned to its place and fixed with the help of a natural corneal substance - collagen.

Stitches do not need to be applied. Restoration of the epithelium at the extremity of the flap occurs independently. After the operation, the cornea is rinsed with a special solution, the drops dropping inflammation are instilled. The described actions are held in front of each other.

Postoperative period

The next day after the intervention, the patient should visit the doctor for a follow-up visit. The hospital sheet is not issued because Lasik is referred to cosmetic procedures.You can immediately return to the usual way of life, although it is recommended at first time to refrain from significant loads.

Visual acuity after surgery can fluctuate for 2-3 days or several weeks.

In the clinic you will be given a memo about what can and can not be done after the operation. The list of restrictions depends on the clinic.

Recommendations for caring for the patient

The results of the operation largely depend on compliance with the rules of postoperative care. And although Lasik - the least traumatic procedure among all, precautions will not harm you:

• In the first day after the intervention, do not rub or squeeze your eyes, try not to strain them.
• Avoid activities related to visual concentration (at least a couple of days).
• Minimize the use of alcohol in the first days after correction.

Although after surgery Lasik to work or study can start the next day, doctors advise to give the eyes a little rest. 2-3 days will be enough.

Patient Reviews

Oleg:

"Doing Lasik in both eyes, diagnosed with astigmatism, nearsightedness-8 and -9. Preliminary diagnosis is long and not expensive, but the doctor assured that without it you can not. The operation took no more than 5-10 minutes, was done without anesthesia, but with anesthesia. Observed rest for several days. The improvements are very good, although I did not return the 100% vision (the doctor warned). "

Inna:

"Lasik - this is the most gentle method of correction from all existing today. The main disadvantage is high cost. I chose this type of surgery because of the absence of a rehabilitation period. "

Olga:

"There are few contraindications, but please check with the doctor. The operation itself is fast, fairly simple, there is no pain. They lower the house at once (it is necessary to appear for inspection the next day). I had myopia -3.5 on both eyes, now I see perfectly. Yes, it's expensive, but it's worth it! ".

conclusions

Lasik is the most modern and perfect method of laser correction, which allows many patients to achieve 100% visual acuity. Precisely say that, and how you will see, the doctor will be able to at the stage of diagnosis (the main goal of the method is to rid patient from lenses and glasses, that is, a 100% correction of vision is not a priori, but improvements will be made. certainly). The operation takes 5-7 minutes, is performed before our eyes in turn. Rehabilitation is easy enough, but still it will be better to give the eyes peace of mind in the early days.
