LASIK for farsightedness - Pros and cons of LASIK for farsightedness

LASIK for farsightedness

Introduction
Farsightedness, also known as hyperopia, is a common type of refractive error where distant objects may be seen more clearly than objects that are near. Today, because of the advancement of technology, LASIK surgery is quickly becoming the preferred intervention for the correction of farsightedness. The following article discusses some important aspects such as the definition of farsightedness, its cause, progress and the use of LASIK for its correction / treatment.

What is far sightedness?
Medically known as hyperopia, farsightedness is a condition in which eyes may see better at distance than at near without glasses or contact lenses but usually require correction for both distances. Hyperopia is often thought to be hereditary, but it is not always the cause. The eyeball may be a little smaller than average.

How does farsightedness develop?
Farsightedness develops in eyes that focus images behind the retina instead of on the retina, which can result in blurred vision. This occurs when the eyeball is too short, which prevents incoming light from focusing directly on the retina. It may also be caused by an abnormal shape of the cornea or lens.

What happened in farsightedness (Signs & symptoms)?
Hyperopia (farsightedness) usually becomes a problem later in life. Most people with farsightedness do not need correction until they reach their forties or fifties. Hyperopic eyes do not bend light enough so that light rays focus to a single spot behind the retina. Things that are far away look blurry because the rays are spread apart instead of focused when they strike the retina.
As for signs and symptoms of this condition, people experience farsightedness differently. Some people may not notice any problems with their vision, especially when they are young. For people with significant farsightedness, vision can be blurry for objects at any distance, near or far.

How LASIK corrects farsightedness?
Refractive Surgery such as LASIK aims to permanently change the shape of the cornea, which will improve refractive vision. Surgery can decrease or eliminate dependency on wearing eyeglasses and contact lenses. There are many types of refractive surgeries and surgical options should be discussed with an eye care professional. However, today, LASIK is one of the most frequently used types of refractive surgery for the treatment of farsightedness.

Objective of LASIK in farsightedness
It must be remembered that success with hyperopic LASIK requires consideration of numerous factors that present less of a problem in myopic eyes. They include the refraction and biometry of the eye, the creation of the flap, and the ablation algorithm. In simple means, the goal of treatment should be to increase the curvature of the cornea without inducing aberrations and this change should be stable over time.
In the Lasik procedure to correct hyperopia, the central part of the cornea is steepened when the laser removes tissue from the periphery rather than the center. It is, however, important to remember that the clinical results are arranged by the type of condition: hyperopia without astigmatism, hyperopic astigmatism, and mixed astigmatism. Therefore, it is important that you know which type of condition you have to determine which results represent your condition. Please discuss which type of condition you have with your doctor prior to reading this information.

What are the benefits of LASIK for the correction of farsightedness?

General benefit: LASIK may reduce overall farsightedness (hyperopia). LASIK may also reduce or eliminate the need to wear glasses or contact lenses to see clearly.

Significant reduction: LASIK surgery is often effective in reducing hyperopia between 0 and +6.0 Diopters.

Some considerations & precautions
The U.S. Food and Drug Administration warn that farsighted patients are more likely to see their vision fade in the years after their LASIK surgery. This is especially true for people whose lens-corrected vision is very different before dilating drops vs. after. Also, as is the case with LASIK for other conditions, the risk of complications such as dry eye, bleeding, infection, pain or cataract development is always there, although the chances of such side effects are very rare.

Conclusion
All in all, LASIK offers an attractive and successful choice for the correction or treatment of hyperopia (farsightedness). However, a choice should be made in this regard after detailed discussion between you and your eye surgeon which should take into consideration all the drawbacks and benefits involved in the procedure.
