Astigmatism is a common vision problem. Astigmatism is not an eye disease, it’s only a refractive error like nearsightedness and farsightedness. All of us possess astigmatism to some degree or other. But not all of us suffer from the eye strain, headaches, and fatigue that comes with the more severe cases. In the past, the best way to treat astigmatism was with glasses or contact lenses. Both of them are good at temporarily giving you some relief from symptoms, however, they do nothing to lessen the irregular curvature of the cornea that’s at the root of the problem.
LASIK for astigmatism offers more benefits than glasses or contacts. LASIK improves eyesight across the entire visual field.
In a normal functioning eye, the cornea and lens are smooth and curved in such a way that they direct light sharply onto the retina. In an astigmatic eye, faults in either the shape of the cornea and/or the lens cause light to fall either in front or at the back of the retina.
How LASIK for Astigmatism Perform
The main function of the cornea that is the dome-like transparent membrane on the surface of the eye to prevent anything from disrupting the delicate layers underneath. The dome-like transparent layer also acts on which light rays pass and therefore plays a big role in how well we can see. While the shape of the cornea is changed, this is identified as corneal astigmatism.
Under the cornea is the lens. In the likewise way as a lens in a camera, the lens in the eye focuses light so that it can be sent to the retina and translated into the images we see. When the lens is an asymmetrical shape, it is understood as lenticular astigmatism.
Nowadays, no matter where the origin, severity, and any symptoms of astigmatism are treatable today.LASIK for astigmatism surgery will correct it entirely.
LASIK, the most successful type of refractive surgery, comprises removing tissue of the cornea and permanently shifting its shape so that it works more like in a normal eye. The treatment of LASIK for astigmatism surgery takes no longer than it takes to nip to the opticians, is absolutely pain-free, and even comes with fewer risks and safety matters than contact lenses.
LASIK for Astigmatism Cost
The average LASIK for astigmatism cost performed in the United States generally ranges between $1,500 to $3,200 per eye. Like various things, the exact cost may link to the technology that will be used during the surgery and the skill of the surgeon’s.
