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…

Antacids and Alignates

Antacids are generally available without a doctor’s prescription and relieve the symptoms of acid indigestion and heartburn (dyspepsia).

The usual ingredients of antacids are magnesium or aluminium and they work by neutralising the acid produced in the stomach which is the cause of indigestion and acid reflux. This group often contain sodium alginate which forms a protective coating over the lining of the gullet and the stomach.

Proton Pump Inhibitors

Proton pump Inhibitors are drugs which shut down the system in the stomach called the proton pump. It is this system which produces acid in the stomach, the leaking of which into the oesophagus causes acid reflux.

These drugs are taken in the form of tablets or capsules, as a powder to be diluted in water or as injections and are used to treat stomach ulcers and a rather rare condition called Zollinger-Ellison syndrome as well as acid reflux.

Omeprazole and Lansoprazole are well known varieties of this particular type of drug although there are several others.

Side effects are rare although they can include diarrhoea or constipation, stomach pains, wind, drowsiness, dizziness and headaches. In unusual cases, a severe allergic reaction can result. My personal experience with Omeprazole was seriously raised blood pressure and severe head pain. However, replacing Omeprazole with Ranitidine and taking blood pressure reduction medication for a couple of weeks sorted out that problem. Read more…
