Am I Suitable for Lasik?

Not all eyes can be treated with lasik. There are some preset guidelines to maintain safety of lasik. Some factors to consider are -

Cost - Lasik is a costly procedure. You need to check if your insurance company will cover the cost. Or if your are

Profession - if you are in the military, aviation etc, do they allow you to undergo this procedure at all. You might be better without lasik, than losing your job.

Refraction Stability - the power of your glasses should be stable or constant for at least 6 months. This is to ensure that your eye power does not vary after the procedure naturally and undo the effect of lasik

Diseases and Medications - Some autoimmune diseases, immunodeficiency states, diabetes, some medications may prevent proper healing after a refractive procedure. Get yourself examined by a physician and get clearence for lasik.

Contact Sports - if you enjoy participating in boxing, wrestling, martial arts etc. there is a definite risk of injury to the eye. Precautions are needed to avoid such sports after surgery for some time.

Adult age - no lasik before 18 years as the refractive stability is not ensured and the power of your eye may change naturally after the procedure.

Large pupils occur under dim light - This can cause symptoms such as glare, halos, starbursts, and ghost images (double vision) after surgery. It may cause difficulty in driving a car at night or in certain weather conditions, such as fog. So you should be prepared that this can occur.

Thin Cornea - Lasik works by changing the eye’s focusing power by reshaping the cornea. There is a minimum limit of corneal thickness below which lasik is not done to avoid ocular complications. Some eye diseases like keratoconus etc. lead to thin corneas and surgery is avoided.

Previous refractive surgery (e.g., RK, PRK, LASIK). A lot more factors need to be considered to determine the outcome and discussion with your doctor is essential.

Blepharitis or inflammation and crusting of the eyelids eyelashes may increase the risk of infection or inflammation of the cornea after LASIK. Dry eye tends to aggravate after lasik.

Cola Linked To Brittle Bones Risk

Drinking cola could lead to weaker bones, experts have said.

A US study found that drinking just four cans of regular or diet cola a week led to lower bone density in women - a condition which increases the risk of osteoporosis.

Experts from the Jean Mayer USDA Human Nutrition Research Centre analysed questionnaires and bone mineral density measurements at the spine and three different hip sites of more than 2,500 people aged just under 60.

They found that drinking cola led to lower bone mineral density in women's hips, regardless of age, timing of menopause, total calcium and vitamin D intake, or cigarette use and alcohol intake.

However, drinking cola was not associated with lower bone mineral density in men's hips or the spine for either men or women.

Dr Katherine Tucker and colleagues reported their findings in the American Journal of Clinical Nutrition.

She said: "The more cola that women drank, the lower their bone mineral density was.

"However, we did not see an association with bone mineral density loss for women who drank carbonated beverages that were not cola."

Men in the study drank an average of five colas a week.

Previous studies have suggested that cola leads to bone mineral density loss because it replaces milk (a source of calcium necessary for healthy bones) in the diet.

But this study related to women whose intake of milk was the same as for women not drinking cola.

Dr Tucker called for further studies to work out if regularly taking in phosphoric acid, found in cola, was to blame.....


She said there was no concrete evidence that an occasional cola harms the bones, but added: "Women concerned about osteoporosis may want to steer away from frequent consumption of cola until further studies are conducted."

A spokeswoman for the National Osteoporosis Society said: "We know that phosphoric acid seems to play a role in bone health and that excessive amounts may lower bone density although there have not been any studies that show exactly why this is.

"What's interesting about this study is that most of the women did seem to be getting a good intake of calcium from other food sources, yet their bone density was affected by drinking as little as four cans of colas a week, which isn't much.

"This study obviously adds to our knowledge but it also makes it clear its results are not definitive and further research is needed."

A spokesman for the British Soft Drinks Association said: "The scientific evidence does not suggest that phosphate, used in the form of phosphoric acid in some carbonated drinks, has a detrimental effect on bone health.

"In any case, soft drinks provide only three per cent of total phosphorus intake from dietary sources, the two main sources being cereals and cereal products, and milk and milk products.

"Consumers can continue to enjoy drinking cola drinks as part of a balanced diet.

"Carbonated drinks can be included within the two litres of fluid everyone should aim to consume each day to stay properly hydrated."
