The loss of the ability of the world is clearly a problem that many people see every day, there are many reasons why a person might fail, the vision, such as genetics, age and special conditions that affect vision. Clearly see some of the conditions that affect a person's ability to have nearsightedness, farsightedness and astigmatism.
People who like to be able to recover their vision in a safe way to do by going through a process that does not mean LASIK, this type of invasive surgeryfocuses on the retina and correcting its curvature, to help focus the images exactly in the center of the retina. The procedure used in LASIK surgery was originally developed in two countries: Colombia and Russia. The procedures that were used to have to correct the curvature of the cornea and perfected over the years and we now know, such as surgery, LASIK (laser in situ keratomileusis) supported. Let's describe some of the conditions that affect vision to provide a better pictureof the reasons why a person may be subjected to this procedure.
Myopia is a condition also known as nearsightedness, is people who suffer from nearsightedness, "said an eye form having too long or the curvature of the cornea is too extreme, if one of these conditions exists, the light that goes does not quite make it through the cornea to the retina is formed at the center before reaching the center of the retina.
Hyperopia is the opposite of myopia in theMeaning that the shape of the eye might be too short or the curvature of the cornea may not be sufficient to create a good focal point. In this case, the light that passes through the cornea provides a focal point that lies behind the retina.
Astigmatism occurs when the cornea is not shaped correctly, and the light that passes through it can not focus on the retina.
People who suffer from one of these conditions may choose to undergo a LASIK surgery to correct the problem withoutHaving to use contact lenses or glasses.
The Post-LASIK Dry Eye Condition
During the entire LASIK surgery is virtually painless, it does not mean that there is no change in the tissues in the eye of the patient, the fact that the tissue was, redesigned to focus images takes time to heal properly. A side effect of the surgery include infection and sometimes dry eye, infectious diseases can be prevented only by a very simple wayAntibiotics, but the most common side effect is the condition known as dry eye.
The normal function of secreting glands, the tear is partially interrupted by the operation which makes these patients feel that as if they had sand in their eyes, while this is not a serious case it can be quite annoying.
