Wavefront technology guides and optimizes LASIK procedures and offers a more sophisticated technique for calculating optical aberrations in your vision. Ophthalmologists now have tools for assessing and treating higher as well as lower order optical aberrations .

The lower order aberrations

Traditional LASIK has treated these three conditions for many years.

• Myopia (nearsightedness)
• Hyperopia (farsightedness)
• Astigmatism (oval or irregularly shaped cornea which causes blurred or double vision)

The higher order aberrations

Wavefront-guided LASIK can do more: it diagnoses and treats these more elusive and puzzling eye conditions such as:

• Halos – radiating circles around lights at night
• Ghosting – faint duplicate images
• Double vision – more definite duplicate images
• Coma – points of light looking like little comets with blurry tails
• Glare – over-bright appearance of lights at night

These subtle visual impairments are talked about in mathematical terms and require an understanding of optics. Your LASIK surgeon can diagnose them in your vision when he examines the way light rays are reflected back from your eyes to his Wavefront system. Every human eye is unique in its combination and severity of vision features. Wavefront

There are some factors that have been found to be linked to AMD, such as advancing age, genetic inheritance, smoking, nutrition, sun exposure and high blood pressure. The one factor that is the most under your control is nutrition. Eating the right foods may help decrease your risk of developing macular degeneration.

AMD is divided into two types, wet and dry. Wet (neovascular) AMD occurs when vessels keep forming to help the blood supply to the retinal tissue which is very oxygen deprived. The vessels that form are very fragile and easily break. This causes damage and bleeding to the tissue. Wet AMD is much more severe than dry AMD. The dry form (non-neovascular) is much more common and is characterized by loss of pigment within the retina.

Doctors have found that people who consumed the largest numbers of vegetables had a 43% lower risk of getting AMD than people who ate the least amount of vegetables. It can’t be just any vegetable though; it must be rich in carotenoids. Vegetables that contain the most carotenoids are spinach, collard greens and kale. Other vegetables also contain it though, just in fewer amounts. These vegetables, from the highest amount to the lowest amount,

Smoking: Simple…Quit. Smoking has been shown to dry out your eyes. In addition, smoking increases the risk of cataracts, glaucoma, and macular degeneration.

Automobile Air vents: Vents pointed at your face and eyes can quickly drain the moisture in your eyes. Make sure to aim the vents away from your eyes or wear sunglasses for protection.

Omega-3: A recent study out of Japan has found that omega-3 supplementation could help prevent dry-eye syndrome.

Vitamin A: Taking a vitamin A supplement or eating vitamin A rich foods such as salmon or eggs can help keep your eyes moist.

Blink: In the electronic age, many of us spend a good deal of time staring at a computer screen. This can irritate even mild cases of dry eyes. When you are concentrating, you tend not to blink as much. Not blinking as frequently will make eye moisture evaporate rapidly. Ever so often, look away from your computer (or television) and take a blink break. Your eyes will thank you.

Humidify: Low moisture levels can dry your eyes fast. The winter can be especially drying during sleep. If possible, get a humidifier for the areas in which you spend a lot of

First of all, you will need to consult your doctor. Discuss with him/her your situation and the problems you are experiencing and an analysis will be made of your situation. Remember, not everyone will be suitable for lasik eye surgery. some of the reasons you may be rejected include:

• being under the age of 18.
• being pregnant
• eyes must be in a healthy condition

At a young age, peoples eyes are still in the evolving stage and any complications which may exist could improve over time. Young people are encouraged to give it a little extra time before considering lasik treatment.

With pregnancy, lasik is discouraged because of the refraction or bending of light due to hormonal changes. Surgery response may be a little skewed for pregnant woman and this also applies to women during the nursing stage.

If you have been having ongoing problems with your eyes and they are not in a healthy or stable condition then lasik may not be an option for you. Your doctor will determine this and be extremely forthright about it. Rejection in this instance is usually a precautionary measure.
