Lasik Eye Surgery Center Nashville, Dallas, Greensboro

Have you ever come across signage which reads �Lasik Dallas�, �Lasik Greensboro� or �Nashville Lasik Eye Surgery�? Did you ever pause to think what they signify? In all probability, they are there to announce a location in the city. What exactly is this term �LASIK�?

Clear vision results when light rays enter the eye and are focused perfectly on the retina (the back of the eye). In order for this to occur, all of the layers of the eye must bend the light rays perfectly. The first layer of the eye is considered the tear film. If the eye is dry, and the tear film is poor, patients will not have their best quality vision. The second layer is the cornea. If the cornea is too steep (as in nearsighted patients), light will not be focused on the retina. The third layer is clear fluid (aqueous humor). The fourth layer is the lens. If the lens is cloudy, this is called a cataract. The next layer is the vitreous, a clear fluid. This is the layer where people get floaters.

Until very recently, eye doctors have measured vision in terms of nearsightedness, farsightedness, and astigmatism (these are all called low order aberrations). Now, new advanced testing with Zyware (usually found in a lasik eye center) can measure other irregularities in the eye called higher order aberrations, which may be responsible for night glare, halos, and poor quality vision. For example, glasses and contact lenses only correct low order aberrations (near, far, astigmatism). The only way to correct high order aberrations is with technology called Wavefront. Selkin Laser Center, the Lasik eye center specialized in Lasik eye surgery, is proud to offer the state-of-the-art Zyoptix Wavefront custom laser that can treat not only your low order aberrations, but also other irregularities that have never been correctable before. It is believed that correcting these irregularities may give patients a higher chance of getting better vision than 20/20 with laser surgery. It may also offer a better quality of vision to patients.

So how do we gather the necessary information to perform this treatment? By using the Zywave aberrometer, any one of Dr. Selkin�s Lasik Plus vision centers located in Nashville, Greensboro or Dallas can identify a map of the visual distortions throughout the entire optical system of the eye. This information does not depend on responses of the patient (such as which is better, 1 or 2). The information is organized to allow for transfer to the Zyoptix laser, which can in turn treat these irregularities. By treating the abnormalities in your eye through a Lasik eye surgery procedure , that glasses and contacts can't, the possibility of crisper vision is available to patients.

The wavefront aberrometer measures the irregularities from the center to the outer edge of your pupil, which is vital because at night, your pupils dilate and more light is scattered at the periphery of your pupils. This technology can measure your prescription under high light situations (comparable to daytime) and your prescription with part dilation (as in dusk), and at night. Hows that for customized treatment? for Lasik Plus vision
