Am I a Candidate for LASIK in Midland or Odessa?
Are You A Candidate? You are probably a good candidate for LASIK if you are 21 or older.
(While LASIK can be safely performed on patients over 18, we advise waiting for further FDA-monitored studies before younger patients are considered for treatment.) have a glasses prescription within a range of about +5 to -8 Diopters. (Astigmatism is rarely a contraindication.) are not pregnant and do not have certain uncontrolled or severe medical conditions.
More than 70 million people in North America are nearsighted, and many of these individuals are interested in correcting their vision with LASIK eye surgery. Myopia is the medical term for nearsightedness. Myopia occurs when an eye is too long for the cornea’s curvature. Light rays entering the eye do not come to a sharp focus on the retina at the back of the eye. Instead, they focus farther forward, producing a blurred image. This is demonstrated in the diagram below. LASIK at our facility can help to correct these problems.
The term “nearsighted” means that you can see “near” objects clearly without your glasses, but objects farther in the distance are blurry. LASIK surgery, when performed correctly, can allow a patient to see clearly at farther distances. There are varying degrees of myopia or nearsightedness.
The more myopic you are, the more blurred objects appear in the distance, the higher your eyeglass prescription, and the thicker your glasses. Of all myopic people, about 90 percent have corrections less than -6.00 diopters. The table below shows the categories of severity for myopia:
|Mild Myopia||< -3.00 Diopters|
|Moderate Myopia||-3.00 to -6 Diopters|
|Severe Myopia||-6.00 to -9.00 Diopters|
|Extreme Myopia||> -9.00 Diopters|
Almost everyone feels that their myopia is severe because of how dramatically dependent they are on glasses and contact lenses. However, only one in ten myopic people are actually in the severe and extreme categories. Despite this small number of severe cases, many myopic patients can benefit from LASIK surgery.
BIFOCAL WEARERS (Presbyopia)
Patients who require the use of bifocals may also benefit from LASIK surgery. Patients who are affected by mild myopia may be eligible to receive this procedure. Presbyopia is the normal process of aging, where the natural lens of the eye loses some of the flexibility that characterizes a younger eye.
This usually occurs between the ages of 40 and 50. Everyone experiences presbyopia — some sooner, some later. Because of this normal process, nearsighted people begin to wear bifocals in their 40s, and those who never needed glasses before may require reading glasses. The one advantage to mild myopia is the ability to remove your glasses after age 40 and to continue to read (your myopia effectively counteracts your presbyopia).
After having LASIK eye surgery, our patients lose this ability. You will typically be normally sighted after the procedure, and you will need reading glasses for small print, like every other normally sighted person at ages of 40 and 50. The excimer laser has no effect on your focusing muscles. Patients who are experiencing the effects of presbyopia cannot be helped by the excimer laser; however, there are new techniques being developed for this condition.
Patients affected by Hyperopia may be eligible to receive LASIK. Turner Eye Clinic can help patients with Hyperopia to see more clearly through the use of LASIK eye surgery. Hyperopia is the medical term for “farsightedness.” It occurs when an eye is too short for the cornea’s curvature. Light rays entering the eye focus behind the retina, and as a result a blurred image is produced.
Farsighted individuals, however, can use their focusing muscles to “pull” the image forward onto the retina. In a young person with severe hyperopia, or once presbyopia sets in around age 45, distant objects are seen more clearly than near objects. Certain laser technologies, such as holmium lasers and hyperopic LASIK at our practice can correct this condition.
Astigmatism is derived from the Greek word “stigma,” which means point. In astigmatism, light is not brought into a sharp point of focus. Rather, the light is more diffused and the image is therefore not clearly seen. By eliminating or reducing the corneal irregularity, the LASIK eye surgery procedure can eliminate or reduce astigmatism while treating other refractive errors.
