Laser eye surgery, sometimes known as LASIK surgery in some circles, can be used to repair a variety of vision problems. However, there are certain risks associated with the operation, and not everyone is a candidate for it. In addition, depending on where a person lives, the procedure might be rather expensive.
The cornea is the outer covering of the eye that protects it from the environment. Astigmatism and myopia are both conditions in which the shape of the cornea can alter in some individuals, resulting in vision problems. In laser eye surgery, this layer is reshaped with the use of laser energy.
The precise way in which laser eye surgery reshapes the cornea is determined by the eyesight problem that the procedure is intended to remedy. Laser eye surgery may correct a variety of visual problems, including nearsightedness and farsightedness.
It takes only a few minutes, and the patients stay conscious during the operation. There are no known consequences. It is also normally painless — if a person suffers discomfort, it is usually a sign that there are difficulties.
This page describes what laser eye surgery is, who it can benefit from, how much it costs, how long it takes to complete, how long it takes to recuperate, and whether or not there are any related short- and long-term hazards.
What is laser eye surgery and how does it work? (LASIK or PRK)
When it comes to refractive laser eye surgery, LASIK (laser-assisted in situ keratomileuses) is the most often performed procedure. LASIK surgery was initially patented in 1989 and has since grown to become the most frequent therapy for refractive eye problems, according to Trusted Source. During the operation, lasers are used to reshape the cornea.
Who may it be able to assist?
It is estimated that over 150 million Americans need corrective eyeglasses to compensate for refractive problems. This figure comes from the American Academy of Ophthalmology.
Refractive errors arise when the eye fails to bend — or refract — the light in order for it to correctly concentrate on the retina at the back of the eye, which is called a refractive error. This is most often caused by the shape of the corneal surface.
Farsightedness is referred to as hyperopia in the medical community. People who suffer from this illness may see items well in the distance, however other objects can look hazy when they are close to them. Farsightedness is caused by the cornea’s curvature being too flat, which causes it to be too thin. A steeper curvature in the cornea can be achieved with laser eye surgery, which can treat this condition.
Nearsightedness, often known as myopia or short-sightedness, is a condition in which a person can see clearly items that are close to them. Distanced objects, on the other hand, may look fuzzy. This is due to the cornea’s curvature is excessively steep, which causes the problem. By reshaping the cornea using laser eye surgery, healthcare practitioners can treat this condition.
Astigmatism is characterized by the presence of an irregularly shaped pupil in the eyes of those who suffer from it. The eye of someone who does not have the disease is spherical, like a soccer ball, however, the eye of someone who has the ailment may have a more football-like form. The abnormal curvature of the cornea can be corrected by laser eye surgery in some circumstances, although it is not always achievable. You can know about What is laser surgery? by clicking here.
Who is inappropriate for this position?
Individuals that are not appropriate
- have had a change in their eye prescription in the last 12 months
- are taking medications that may cause changes in vision
- are in their 20s or younger, although some experts recommend not being under the age of 18 years
- have thin corneas, which may be unstable following laser eye surgery
- are pregnant or nursing
The most significant advantage of laser eye surgery is that the vast majority of patients no longer require corrective eyeglasses in order to see well. Individuals may elect to have the surgery for a variety of reasons, including the following:
- being unable to wear contact
