Lasik eye surgery is commonly known as laser eye surgery or laser vision correction. The term “LASIK” stands for laser in-situ keratomileusis. It is a type of refractive eye surgery which is performed on patients to correct their vision. People who suffer from short-sightedness (myopia), far-sightedness (hyperopia), or have astigmatism opt for this surgery. Shreveport eyes specialists is one of the best facilities in Shreveport, Louisiana for LASIK.
How the eyes function?
A light ray enters into the human eye through the Iris and forms an image on the retina which is at the back of the eye. When the image so formed is sharp and perfectly focused on the retina, the vision is said to be clear. When the image ends up being focused elsewhere and not on the retina, it results in blurred vision.
Types of Vision irregularities
- Nearsightedness (myopia) is a condition is where one can see objects that are nearby very clearly, but distant objects are blurred out. Due to dysfunction of the eyeball, the light rays form a focused image before reaching the retina causing a blurry image of things that are far away. For example, one can read a book but not enjoy the scenery with naked eyes.
- Farsightedness (hyperopia) is a condition is where one can see far objects clearly, but nearby objects are blurred out. Due to another type of dysfunction of the eyeball, the light rays from a focused image after the surface of the retina causing a blurry image of things that are near. For example, one can enjoy a sunset but not read a newspaper with naked eyes.
- Astigmatism is a condition which causes complete blurry vision because of the shape of the cornea. The unevenness of the surface of the cornea disrupts the image formation.
An ophthalmologist conducts the surgery by inserting a laser on the eye’s cornea to cut and reshape it according to one’s vision condition, which results in the improvement of visual acuity. After getting a LASIK, most patients with severe vision malfunction have a clearer vision and depend less on eyeglass or contact lens. Many patients no longer need any support of such throughout a lifetime.
This is a painless surgery which involves no stitches. As of 2016, over 40 million surgeries have been performed worldwide since 1991. Data from the past 10 years show that LASIK has had a success rate of 96%. With LASIK, one can do all the activities without any disturbance of balancing glasses over the nose or being extra cautious for contact lenses. LASIK ensures patients clear vision from the very next day of the surgery. It is a permanent solution to handle blurry vision.
