Radial keratotomy (RK) is a refractive surgical procedure employed to correct myopia or nearsightedness. Radial Keratotomy came into existence by accident rather than through meticulous research. The procedure was discovered by Dr. Svyatoslav Fyodorov when he operated one of his patients who had met with a bicycle accident. The boy wore eyeglasses, which broke on impact, and the glass splinters lodged into his eyes. The doctor had to make several radial incisions in the corneal tissue in order to extract the glass. When the cornea healed, the doctor found that the boy’s eyesight was significantly improved.

In radial keratotomy (RK), a series of micro-fine incisions are made in the outer portion of the cornea with the aid of a high-precision calibrated diamond knife. The surgeon administers a local anesthetic, since the incisions are superficial and the procedure is fairly painless. The corneal thickness of the patient’s eye is measured prior to the surgery. Before the incisions are made, the diamond-edged cutting instrument is precisely set under the operating microscope. Thus by flattening the curvature of the cornea in such a manner, RK can easily correct myopia or nearsightedness. Read more…

Commonly called ‘heart burn’, acid reflux disease is a condition in which the liquid content of the stomach regurgitates (backs up, or refluxes) into the esophagus.

It’s annoying and painful.

But you want to know the truth, the reflux of the stomach’s liquid contents into the esophagus occurs in most normal individuals. However, when heartburn becomes acid reflux disease or Gastro esophageal reflux disease, commonly referred to as GERD, it is s real problem. That is because with GERD, the acid is stronger and stays in the esophagus longer causing more discomfort.

Most often, you will experience this during the daytime when you are upright, sitting straight, or standing. You body handles this reflux by the fluid flowing back down into your stomach. You swallow more during the daytime therefore draining the acid back to where it belongs. Your salivary glands produce saliva that also contains bicarbonate that acts to neutralize the acid your stomach has kicked up.

At night though, you may have a greater problem when acid reflux disease occurs that is because while sleeping, gravity does not work as well lying down, your constant swallowing stops, and the production of saliva is reduced.

Certain conditions make a person more prone to acid reflux disease, this GERD. For example, while you are pregnant, this can be a serious problem. Elevated hormone levels of pregnancy probably cause reflux by lowering the pressure in that part of your body known as the lower esophageal sphincter. Also, the growing baby puts more pressure on the abdomen. Both of these effects of pregnancy tend to increase the risk of GERD.

If your acid reflux disease is a minor condition, then you should only experience minor symptoms. These would include primarily heartburn, regurgitation, and nausea. However, if the condition is complicated, then watch out for the following symptoms. Read more…

Types Of Diabetes

There are two types of diabetes, and they really are two quite different diseases. In type 1, or insulin-dependent diabetes, insulin injections are needed. But in type 2, or non-insulin-dependent diabetes, most people can keep their condition under control with just diet and medication. This type of diabetes is actually much more common than the insulin-dependent type.

How do I find out which type of diabetes I have?

Your doctor will tell you what type of diabetes you have and what you need to do. You can also ask your doctor to refer you to a Diabetes Education program. There, trained health professionals can teach you about diabetes and insulin.

What Is Insulin?

Insulin is classified according to how long it works in the body. There are five different types of insulin, ranging from short to long acting. Some insulins are clear in appearance, while others are cloudy.

Types of insulin
The five types of insulin include:

1. Rapid onset-fast acting insulin
2. Short acting insulin
3. Intermediate acting insulin
4. Mixed insulin
5. Long acting insulin.

Diabetes And Healthy Eating

Healthy eating, combined with regular physical activity and weight control, is important to manage diabetes.

People with diabetes should eat mainly high fibre carbohydrate foods such as wholegrain breads and cereals and vegetables and fruit. They should also reduce their intake of fat, especially saturated fat. Limiting the serving size of your meals is often required to maintain a healthy body weight. It’s also a good idea to see a dietitian who can help develop a healthy eating plan. Read more…
