Eye-glasses and sport
Nearly a quarter of the world's population suffers from myopia( "myopia") - 70-90% of the inhabitants of Asian countries, 50% of the UK population, 30-40% of the population of continental Europe and the United States of America, 10-20% of Africa and about 13% of Brazilians( 1).
It's no secret that playing sports with glasses is not always convenient. Many athletes use both contact lenses and think about performing a vision correction operation with an excimer laser( LASIK).FitSeven will help you decide if you need this operation.
Imagine if you were offered a special procedure, after which your body would look perfect. Muscles would remain bulky and embossed even without weight training, and the fat layer did not increase in any way of life.
One "but" - the body would remain unchanged only externally. Any problems associated with malnutrition and low levels of activity would affect the internal organs and health. Operation LASIK, in fact, is this "magic" correction procedure.
An external solution to the
problem Let's return to the example of an ideal body. The impossibility of recruitment of subcutaneous fat will remove the psychological barriers to nutrition - a person will begin to eat abundantly and, most likely, not too correctly. The result will be obesity of the liver and many serious diseases.
In turn, laser vision correction, which is only an external solution to the problem of myopia, in no way solves the cause of this disease. In addition, constant correction of vision leads to atrophy of natural functions and muscles of the eyeball.
What is LASIK?
In fact, in LASIK operation( the abbreviation of the phrase Laser-Assisted in Situ Keratomileusis - "laser keratomileus"), a constant "contact" lens is formed in the cornea of the eye, changing the direction of the light rays and correcting the point of focusing on the retina.
The top piece of the eye cornea with a diameter of about 8 mm is cut halfway and raised, then the laser burns out the analog of the contact lens directly after the cutoff, then the corneal flap sits in place and is glued in a natural way( 2).
Dangers and complications
LASIK is not recommended for people under 18 years of age, for diabetics, for pregnant women( eyes that are not completely restored after surgery may be severely damaged due to increased intraocular pressure during labor).Also, the procedure is not performed with a thin cornea.
The risk of developing serious complications after laser correction surgery is estimated at 10 to 18%, and the risk of secondary and subtle complications is almost 100%( 2).In other words, almost every person is facing certain problems.
Problems after operation
Among the negative consequences of the operation are common dysfunction of the cornea, fluctuations in visual acuity due to hyper or hypocorrection, increased sensitivity to light, dry eye syndrome, and so on. Retinal detachment is observed in 0.4% of cases.
A number of complications occur decades after surgery in the course of aging. It is important to remember that there are no clear figures about the risk of such complications, because the technology of the operation is constantly being improved and is changing quite a lot.
Should I do laser correction?
Since the late 1980s, tens of millions of people have gone through a laser correction operation. But, unfortunately, it is impossible to guarantee that after years with their eyesight nothing will happen, and the modified eye successfully adapts to the natural aging processes.
Despite the aggressive advertising of laser-corrected vision clinics claiming a low level of risk for this operation, in reality LASIK is a rather controversial procedure. Its main disadvantage is irreversibility. If something goes wrong, it's impossible to go back.
The operation of laser vision correction leads to serious complications in almost every fifth operated person. In addition, it is important to remember that this procedure is exclusively cosmetic, and does not struggle with the causes of impaired eye functions.
