Lasik Eye Surgery

Lasik stands for laser-assisted in situ keratomileusis, and is a surgical procedure used to “cure” shortsightedness, longsightedness, or astigmatism. “Keratomileusis” is the carving of the cornea in order to reshape it. Lasik Permanently changes the shape of the cornea using a special lazer called an eximer lazer.

As the laser reshapes the cornea, it changes the angle at which you see images and therefore strengthens your vision significantly. This reshaping adjusts and strengthens the power of your cornea to focus on objects near and far. If you are nearsighted, your doctor uses the laser to flatten your cornea that is too-steep. If you are farsighted, your doctor uses the laser to make your cornea steeper because it is too flat. For astigmatism, the laser can be used to smooth an irregular cornea into a more smooth shape. There are few other procedures like Lasik Eye Surgery that can give you these amazing results and permanently change the shape of your cornea in just minutes.

The lasic procedure of lasik is:

  • A suction ring is placed on the eye to stabalize and monitor pressure
  • A microkeratome, a cutting instrument, is attached to the suction ring. This blade cuts a flap in the cornea
  • The exposed inner layer of the cornea is reshaped with an eximer lazer
  • The corneal flap is returned to the original position

The patient walks in to the surgery, have the procedure, and walk out again being awake the whole time. The doctor performing the surgery may also administer a mild oral sedative.

The marketing for this procedure says that lasik provides benefit to millions of people, however, it doesn’t really solve the underlying cause of poor vision. If they were myopic before, their eye is still mis-shapen. They may be able to see perfectly well after the surgery, but years down the line myopia may return. There are also possibilities of complications that could affect your vision.

Healthy Vision and Eye Disease Prevention

Often seniors assume that poor eyesight is a natural part of growing old. By age 65, it is estimated that 1 in 3 Americans have some form of vision impairing eye disease. By detecting and treating eye disease early through annual eye exams, seniors can preserve their sight.

In a study by John Hopkins University to try to convince Medicare and insurance companies to put stronger emphasis on preventive eye care The report looked at a 5 percent sampling (approximately 1.5 million people) of Medicare beneficiaries continuously enrolled from 1999 to 2003 and concluded that those with moderate, severe and total vision loss experienced increases in depression, injuries and the need for nursing home facilities.

More than half of the cases in the study were due to age-related macular degeneration (AMD) and glaucoma. A sizable number of cases of vision loss were due to cataracts that had not been surgically removed.

There are four major eye diseases that affect seniors the most; cataracts, glaucoma, age-related macular degeneration and diabetic eye disease.

Cataracts

A cataract is a clouding of the lens in the eye that affects vision. Most cataracts are related to aging and are very common in older people. In fact, by age 80, more than half of all Americans either have a cataract or have had cataract surgery.

Symptoms are usually cloudy or poor vision, poor night vision, halos around lights, colors seem faded and the need for frequent changes in prescriptions.

In the early stages difficulty from cataracts may be improved with new eyeglasses, brighter lighting, anti-glare sunglasses, or magnifying lenses. By the later stages cataract surgery may be need to remove the clouded lens and replace it with an artificial lens.

Glaucoma

Glaucoma is a group of diseases that can damage the eye’s optic nerve. It is one of the leading causes of blindness in the United States, and the most common cause of blindness among African-Americans. More than three million people have glaucoma, but half do not realize it because there are often no warning symptoms.

Damage progresses very slowly and destroys vision gradually, starting with the side vision or what is called peripheral vision. One eye covers for the other, and the person remains unaware of any problem until a majority of nerve fibers have been destroyed, and a large part of vision has been destroyed and straight ahead vision is affected. This damage is irreversible.

Treatment cannot recover what has been lost. But it can arrest, or at least, slow down the damage process. That is why it is so important to detect the problem as early as possible, to be able to start treatment with as little damage to the vision as possible. Medication in the form of eye drops or pills are the most common early treatment for glaucoma. Laser or conventional surgeries are also available options when needed.

Age-related Macular Degeneration (AMD)

The leading cause of vision loss in over 60s is age-related macular degeneration (AMD). Macular degeneration doesn’t always cause total blindness, but it slowly affects the part of vision that is crucial for recognizing faces and doing detailed work. Blurred vision or a need for more light when you’re reading may occur first. Then, straight lines may begin to appear crooked, and dark or empty spaces may begin to block your central vision, similar to a blind spot when you’re driving.

Diabetic Eye Disease

Diabetes is a disease in which the body does not produce or properly use insulin. There are two types of diabetes; Type 1- is when the body fails to produce insulin, the hormone that allows cells to turn food into energy. Type 2- is when the body is resistant or fails to properly use the insulin, this is the most common form.

Diabetes is already the number one cause of blindness in the United States. Diabetics are 25 times more likely to lose vision than those who are not diabetic according to the American Academy of Ophthalmology.

Proper treatment of diabetic retinopathy can cut the risk of vision loss by over half. Treatment before diabetic retinopathy causes severe loss is much more effective than later in the disease. For this reason, early diagnosis is critical in order to prevent visual loss and blindness. Control of diabetes and blood pressure is important; intensive control of blood glucose can delay onset and slow progression of retinopathy.

Is it Possible to Improve Your Eyesight Naturally?

Why is it that millions of people world wide wear glasses? There are not many animals that need glasses, so what makes us different?

It’s a fact that glasses weaken your eyes because they encourage you to use your eyesight in the wrong way, and this can actually promote visual defects. Advice these days is to get your eyes tested every six months or year and usually to buy new, stronger lenses each time. With this rationale, if glasses are the correct form of treatment the eye deterioration should be at least arrested, if not improved. This is not the case. The eyes usually must they be continually strengthened because the eyes, under their influence, have weakened. Glasses, contact lenses, and eye surgery only treats the symptoms, not the causes of poor vision. They can also possibly lead to other problems later in life.

We become so accustomed to stronger and stronger lenses that we just accept what we perceive as the inevitable. This is the accepted norm which is promoted by most opticians. We also tend to believe them as they are the professionals.

A hundred years ago Dr. Bates taught us that declining vision is not necessarily inevitable and that natural healing methods and techniques are well worth studying. So before you pay for laser surgery or yet another pair of expensive glasses or contact lenses, take some time to explore the alternatives. It could save you a lot of money and be much more beneficial in the long run.
