The Lasik Procedure and What it Comprises

  • Posted on July 2, 2009 at 7:15 am

While many people have heard the term Lasik, not very many people truly understand what it comprises. Lasik stands for Laser-Assisted In Situ Keratomileusis, which is obviously a very large mouthful. To most people, this means very little to you. In more simple terms, LASIK eye surgery is when the surgeon uses a laser to change the shape of your cornea, which results in improved vision.

The cornea focuses light that enters your eye and then bends and focuses that light to produce an image on your retina. Unfortunately, sometimes a person’s ability to focus light is diminished (usually due to a mismatch between the cornea’s ability to focus light and the length of the eye). As a result, a person’s vision may be blurred or distorted.

During the actual LASIK procedure, a tiny cut in made in the cornea, which results in a small flap. This flap is then folded back. Once this has been accomplished, a surgeon will use a laser to vaporize a small portion of the cornea (called a stroma). After enough of the stroma has been removed, the surgeon then folds the flap back up. As a result, the cornea is now reshaped resulting in an improved ability to focus and bend light, which results in an improved image on the retina.

When this occurs, a doctor will diagnose a patient with refractive errors. In order to remedy this situation, other than LASIK eye surgery, there are two other primary refractive procedures that one can undergo. The first is RK, which is Radial keratotomy. During this procedure, tiny incisions are made in the cornea to flatten it slightly. The second procedure is called PRK, which is Photorefractive keratotomy. This procedure is very similar to LASIK. The main difference is that in PRK, the laser is used on the outside of the cornea.

Also, one should be confident and focused to lose weight.Basically, overweight and obesity occurs due to the accumulation of excess of adipose tissue, this accumulation may occur due to the over consumption of fats and carbohydrates. People who consume more and more food without doing any exercise, gain excess weight. This excess weight may lead to many diseases in the future and also in the present. It leads to many cardiac diseases like cardiac arrest, heart attacks etc. We know that eating healthy food is very important, but eating too much of food is not acceptable as our body won’t accept it .So eating should be done in accordance with the usage of food by the body people who just go on and on consuming the food , but do no exercise will obviously gain weight . So this practice should be avoided , people should eat only that much amount of food which their body can use to perform several functions of the body and also some external functions as well . Let us take for instant the example of people who stay in villages and the people who stay in metropolitan cities, the people who stay in villages do more of physical exercise then the people who stay in the cities as they go to the fields and use energy, so whatever they eat is consumed by their body. Whereas in the case of the people who live in the cities, do not go to fields but they go to offices where most of the work is done on the computer itself. Therefore no energy is consumed in doing the work. Hence people living in the cities tend to gain more weight than the people living in the villages. So the obese people should do exercises in order to lose weight and lead a healthy life. It will only help you to get a better life.

The Facts About Fillings

  • Posted on July 1, 2009 at 10:12 pm

Fillings are very common with dental work, as they present a way to repair a tooth that has suffered from decay or a cavity back to it’s original shape. When performing a filling, the dentist will remove the decayed area of the tooth, clean around it, then fill in the area that he has removed with a special material that will cater to the shape and form of the tooth.

Fillings work by closing out the area where the bacteria enters into teeth, helping to prevent any type of decay in the future. The materials used for fillings include porcelain, gold, composite resin, and amalgam. There is really no best type of filling, as several factors come into play. Your reaction to different material, the shape of the tooth, extent of repair, and where the filling is needed will be determining factors as to what material is used with your filling.

The gold fillings that are used are made in a laboratory, then cemented into place by the dentist. Gold material fits well with the gums, and can last you for many years. Gold is considered by many to be the best, although it is also the most expensive and will require you to visit the dentist several times before the filling will be complete.

Silver fillings on the other hand, are less expensive than gold materials and they can be quite resistant to wear. With their color being dark, they are easier to notice than composite or porcelain fillings, and aren’t recommended for visible areas of the mouth, especially the front teeth. Composite fillings are a common type of material, as they match the color of your teeth. The material that makes up the composite filling is mixed then placed directly in the cavity, where it hardens. They last several years, although composite isn’t recommended for large cavities, or areas where they may chip.

The final type of filling is porcelain. Porcelain is very common, and produced in lab where it will be matched to your teeth then bonded to the affected tooth. Porcelain fillings match the color of your teeth, and are resistant to any type of staining. The costs for porcelain fillings can be very expensive, some costing as much as gold fillings.

If a cavity, decay, or even a crack has managed to damage a large area of the tooth, you may need a crown or a cap. If the decay has managed to get to the nerve, you may end up needing a root canal to get rid of the dead pulp. When the dentist decides he can fill your tooth, he will remove the cavity then fill the hole with a material listed above. Depending on your insurance and what you can afford, you can choose which one you want or take his recommendation. In most cases, porcelain or composite fillings will be recommended. Gold fillings are popular, although most people want a filling that will match the natural color of their teeth.

Keep in mind that only a dentist can make the decision regarding fillings. When you visit for your routine checkup, the dentist will look in your mouth and use instruments that will let him examine the surfaces of your teeth. If he finds any cavities, he will usually recommend a filling. You won’t feel anything, as he will numb the area he is going to be filling. It normally takes less than an hour, and you’ll be up and at ‘em before you know it. A filling is great for cavities, as most look natural and they won’t result in the loss of your tooth.
