Thanks to large-scale advertising campaigns of ophthalmological clinics many people with poor eyesight think that their only chance is an operation. At the same time, very few people think that laser correction of vision has not only advantages, but also disadvantages. And they must be taken into account, agreeing to the operation. Otherwise, the consequences of it can become a very unpleasant surprise.
Can I do a laser vision correction?
This question can be answered for sure only by specialists. And then you will need to go through a whole complex of examinations beforehand, to take tests. And that the operation did not do much harm, as practice shows, it is best to consult several different doctors.
Before you understand whether it is worth doing a laser eye correction or not, you need to figure out what kind of procedure it is. It is a photochemical ablation of corneal layers carried out by a laser beam. If to speak in clear and simple words, during the operation with the help of the laser the curvature of the cornea changes. This improves vision.
One of the most effective modern methods is LASIK. This operation of laser vision correction is similar in principle to all other procedures:
- First of all, anesthesia is done five minutes before the start. There will be no painful sensations. All that the patient will feel is touching the eyeball.
- The patient is laid on the couch and treated with his eyes with disinfectants.
- To keep the eye open, a special bracket is placed on it.
- After that, the doctor will say to focus the vision on the laser. The patient will have to look at this point throughout the operation.
- At this time, the beam raises a piece of the cornea and removes the stroma.
Ocular tissue grows very quickly, so to return the shred in place, no need to apply seams.
Pros and cons of the method of laser vision correction
Not everyone can perform the operation. In general, it is prescribed for:
- high degree of myopia ;
- a large difference in the anomalies of refraction of the right and left eyes;
- impossibility to wear glasses or contact lenses .
Just so that to make your life more comfortable, to conduct an operation is strictly not recommended.

There is a laser eye correction and its cons. And the main one is that it does not cure the eye, it just removes the symptoms. And this means that after a while the effect of it will weaken, and the person may again need glasses.
In addition, the operation is quite expensive, and it is contraindicated for patients under 18 years of age, because children and adolescents have an eyeball at the stage of growth and can not predict how the refractive power of a transparent medium will change.
