For many decades, scientists have been looking for a safe and effective way of restoring visual acuity, and finally, laser correction, which, acting on the refractive optical environment inside the eye (cornea), changes its shape. This restores the normal focusing of the picture on the retina - in the place where it should be in a person with healthy eyesight.
Like any operation, laser vision correction has certain contraindications - they are set by the doctor after a thorough diagnosis.
Who can not make a correction?
Due to the fact that during pregnancy, the vision of a woman worsens somewhat, the ladies in an interesting position with laser treatment will have to wait. The same applies to women planning to become pregnant within the next 6 months and nursing mothers.
Also, eye surgery (correction of vision with a laser) is contraindicated when:
- progressive myopia;
- glaucoma ;
- diabetes mellitus in severe form;
- cataract ;
- dystrophy or degeneration of the cornea;
- inflammation of the eyes;
- changes in the eye fundus;
- diseases of the endocrine system;
- iridocyclitis (inflammation of the iris).
Do not perform a correction in the case if there is an operation in the history of an operation connected with detachment of the retina of the eye.
Restrictions after laser vision correction
In the absence of contraindications, the operation is performed under local anesthesia for a quarter of an hour, and the patient can immediately go home. However, recovery from laser vision correction requires compliance with certain rules. Doctors usually advise:
- Do not touch the eyes until the next inspection;
- do not wash your hair for three days;
- do not use the first week of cosmetics for the eyes;
- a few days not to use the computer, do not drive;
- for a month not to engage in contact sports.
Consequences of laser vision correction
In general, the operation is as safe as possible, and the risk of its dysfunctional outcome is less than 1%. All possible complications in this case are divided into three categories.
- The final result of the correction is positive, but the rehabilitation period is increasing: corneal edema, an allergy to medications that take after laser correction of vision, omission of the eyelid, extremely delayed re-epithelialization.
- The final result of correction depends on intensive therapy with special medications, a second operation may be required: insufficient moistening of the mucosa; bacterial or herpetic keratitis; slight opacity of the cornea.
- A second operation is required: partial removal of the epithelium or partial correction, severe opacity of the cornea, regression of the refractive effect.
Choosing a doctor and clinic, you should be very careful, since it is the qualified diagnosis - the key to successful correction of vision.
