Laser eye surgery is a medical procedure that involves sculpting of the cornea with a laser to treat eye-related disorders like Myopia, Hypermetropia and Astigmatism. The first ever laser eye surgery procedure dates back to approximately 30 years. Although the concept of laser eye surgery has existed for quite a while now, it was not until very recently that it gained its fair share of recognition.
In essence, laser treatments for eyes help in the correction of refractive eye disorders that may occur due to imperfections in the shape of the cornea or eyeball. Cornea is recognized to be the front and transparent layer of the eye. Refractive errors are responsible for the imprecise focus of light from an object on the retina of the eye. This leads the viewer to suffer a blurry vision. As mentioned above, the three kinds of refractive errors and their nature have been explained below:
1. Astigmatism (unevenness in the curvature of eye surface) -Due to the unevenness of the lens and the cornea, images of the objects fail to focus in a sharp manner on the retina hence leading to a blurry distant vision.
2. Myopia (Near sightedness) -The eyeball stretches out to be longer than its normal size. As a result, the images instead of getting focused on the surface of the retina focus in front of it.
3. Hypermetropia (Farsightedness) –In this disorder, the ability to focus on objects that are near, diminishes. On the contrary, one can clearly see the objects at a distant site. The eyeballs diminish to a shorter size or the cornea flattens way too much leading images to focus behind retina.
Detailed below are the various laser eye surgery procedures that you can undergo as prescribed by your ophthalmologist or as required by your eye - condition:
1. Contoura Vision – Correction of spectacle power by a completely bladefree laser system, which is FDA approved and which gives you two additional benefits over just correcting your spectacle power. It also corrects your corneal irregularities and works on visual axis providing super human vision, unmatched by any other laser procedure
2. Smile – Utilizes only one laser to cut two planes of tissue on the cornea and then pulls the lenticular tissue with forceps.
3. Lasik eye surgery procedure (Laser in-situ Keratomileusis):
Lasik Laser eye surgery is one of the most recognized laser eye surgery procedures currently existing in the market. It constitutes around 90 to 95 percent of all forms of laser eye surgery and has the widest range of uses. Under the procedure of lasik laser eye surgery, a thin flap is created in the cornea using a Microkeratome blade or Femtosecond laser. These flaps are then made to fold back so that the surgeons are allowed to scrape off some of the corneal tissue. Once this is done, the corneal flap is placed back to cover the area from where the tissue was scraped. In cases of Myopia, surgeons aim to flatten or at least reduce the steepness of cornea. Alternatively, the aim is to increase the steepness of the cornea for patients of Hypermetropia.
4. PRK (Photo Refractive Keratectomy):
Similar to lasik, in this procedure of laser eye surgery, surgeons use a laser to reshape the cornea and to scrape some of the corneal tissue. Recovery is more time - consuming in comparison to a lasik laser eye surgery.
