Common Eye Conditions

LASIK Candidate


If you wear contact lenses or eyeglasses and want to rid yourself of the inconvenience and burden that comes with them, you should consider permanent treatment.  NVISION Laser Eye Centers offer treatments plans for just about anyone who depends on contacts or glasses.

If you wear glasses or contacts, you may have one of the following common eye conditions:

Nearsighted (Myopia): More than 70 million people in North America (about one in four) are nearsighted. Myopia is the medical term for nearsightedness. It occurs when your eye is too long in relation to the curvature of your cornea. Myopia causes light rays entering the eye to focus in front of the retina, producing a blurred image.


Farsighted (Hyperopia): Hyperopia is the medical term for farsightedness. Hyperopia occurs when your eye is too short in relation to the curvature of your cornea. Light rays entering your eye focus behind the retina, producing a blurred image. Some farsighted people can use their focusing muscles to pull the image forward onto the retina, allowing them to see clearly. But others, who cannot overcome the effects of severe hyperopia, need glasses for distance vision as well as reading glasses or bifocals.

Astigmatism: Many patients with myopia and hyperopia have some degree of astigmatism, or an oval shape, to their corneas. It occurs when your cornea is shaped more like a football than a basketball. As a result, you experience distortion or tilting of images due to the unequal bending of light rays entering your eyes. People with high degrees of astigmatism have blurred vision for both near and distant objects.

Older Eyes (Presbyopia): Presbyopia is part of the normal process of aging. It develops as the lens of the eye loses some of the flexibility that characterizes a younger eye. Everyone experiences the effects of presbyopia, typically between the ages of 40 and 50. Nearsighted people who become presbyopic may require bifocals, and those who never before needed glasses may require reading glasses.

Cataracts:  A cataract is a progressive clouding of the human lens inside the eye. Initially, the cataract changes the focusing power of the eye, and a change of glasses can satisfactorily improve vision.  Gradually, clarity decreases so that visual tasks become increasingly difficult, despite the best possible glasses.  A person with cataracts views the world as if through a dirty window or a windshield that needs defrosting.  Reading, driving, computer work, hobbies, and athletics become more difficult and eventually impossible due to diminished vision.

The vast majority of patients will meet the conditions for laser vision correction surgery.  In order to determine if you are a candidate, please contact one of our patient care coordinators today.   If LASIK is not right for you, there are alternatives forms of treatment, such as PRK, intraocular lens, and others that may be appropriate for you.  A comprehensive eye exam with a board-certified optometrist will help ensure the best possible course of treatment.
