While countless people who suffer from refractive disorders such as nearsightedness, farsightedness, and astigmatism have traditionally corrected their vision issues with glasses or contact lenses, you may have decided that these forms of vision correction simply aren't for you. Maybe you're tired of constantly maintaining and replacing glasses and contacts, or maybe you'd just prefer the most unencumbered experience possible.
Whatever your reason for seeking another way, we have that other way here at Texas Eye Surgeons. LASIK surgery can permanently change the way your corneas refract incoming light for lens-free visual clarity.
LASIK is short for "laser-assisted in situ keratomileusis." True to its name, it uses the advanced technology and unbeatable precision of state-of-the-art surgical laser tools (instead of traditional manual devices) to reshape your corneal tissue. To understand how this procedure corrects your vision, it's first important to understand how vision normally works.
The cornea is like a "window" into the eye, receiving light so it can be refracted into clear images on the retina. But an abnormally-shaped eyeball or cornea can make normal refraction impossible, resulting in the blurred vision of myopia, hyperopia, and astigmatism. (Another refractive error, presbyopia, results from age-related stiffening of the lens.)
Traditionally, compensating for these refractive errors has involved placing corrective lenses in front of (or directly onto) the corneas. But modern medical technology has made it possible for us to simply change the refractive behavior of the cornea itself by subtly re-sculpting it.
In a typical LASIK surgery, a femtosecond laser tool makes an extremely fine incision along the perimeter of the cornea, allowing us to lift up a flap of the outermost corneal tissue. Our ophthalmologist, Dr. Ali, then uses an excimer laser to vaporize a specific amount of underlying corneal tissue in exactly the right patterns to compensate for your refractive error. The flap of outer tissue is then replaced over the cornea. The incision is so precisely made it will actually heal on its own, without stitches.
The first step toward a successful LASIK procedure is a detailed evaluation from our Plano ophthalmologist to determine whether you're a good candidate for it. If you're under 18 or your prescription is currently changing, for instance, you may not be ready to receive the procedure just yet; if you have an unusually thin corneal tissue, we may direct you toward an alternative procedure such as PRK. During your evaluation, we will use a pachymeter and other tools to measure your corneal tissue depth and curvature in great detail.
You may be astonished at how quick and easy the actual LASIK surgery is. Numbing eye drops to ensure that you feel no pain, while the procedure itself takes just a few minutes. Any blurred vision or minor irritation should clear up within a day, leaving you with remarkably clear vision. (Be aware, however, that you still might need reading glasses if you suffer from presbyopia.)
