What is Nearsightedness?
Myopia, or nearsightedness is the inability to concentrate properly on distant objects. The objects that are close can occur in normal care, but that distance will be blurred. It is possible that you can read text in books or newspapers without a problem, but you have trouble reading road signs until you are in close proximity.
Myopia is usually caused by a natural change in the shape of the eye that causes your eye to be more oval, instead of the usual round shape. This causes the light entering the eye to focus in front of the retina, resulting in an out of focus image.
Symptoms of Nearsightedness
The main symptom is blurred vision when focusing on distant objects. If you find yourself squinting when you look away in scenes may be nearsighted. If you have trouble seeing the words on a blackboard or cinema screen, but you can read a book without a problem, you’re probably nearsighted. A routine review of the eyes can determine if you are nearsighted.
Diagnosis Nearsightedness
An eye exam will determine if routine is nearsighted. Myopia usually begins in childhood or early adolescence and their effects can vary from mild to moderate to high. Mild cases may not require corrective action.
Most children are born Farsighter slightly, but this is corrected itself the normal development of the eye as the child ages. However, if the correction is too sharp, light rays are focused in front of the retina instead of directly onto the retina, and the child becomes nearsighted.
Treatment of Nearsightedness
Glasses or contact lenses can treat myopia, but surgery can also be done to cure myopia reshaping of the cornea.
Assists LASIK surgery to correct nearsightedness by using a laser to reshape the cornea, and has been used successfully since the early 1990’s. The purpose of this procedure is so you can see without corrective lenses or to be less dependent on corrective lenses. LASIK procedures cause permanent changes in the eye that can not be undone.
The LASIK procedure involves cutting a flap in the cornea. This flap is then folded back and amending the laser contour. Following this change, the flap is folded back to its normal position and the healing process begins. Most patients notice an immediate improvement in their vision.
Most people who have elected to LASIK surgery are very satisfied with the results achieved. In many cases, patients LASIK surgery can see well enough to eliminate the need for corrective lenses. However, some patients will have to wear corrective lenses, under certain conditions.
How long LASIK?
The research data collected has shown that almost all patients have undergone LASIK vision improves immediately after treatment and at least 40% of patients were able to avoid the use of corrective lenses during the ten years following the procedure. It is normal for the eye to change shape as a normal part of aging process, so it is recommended retreatment if significant reshuffle comes after several years.
