Desiring to have great vision again is not an impossible dream. With LASIK eye surgery, you can now have clear vision. Researching LASIK is easy with the internet and maybe you have done your homework and are almost ready to undergo the surgery. Vision correction surgeries are becoming easier and more advanced these days. With more choices in LASIK eye surgeons than ever before, now might be the time for you.

With so many eye surgeons performing Lasik these days, you still need to find the right surgeon to do your procedure. No matter where you live, there are probably plenty of qualified Lasik eye surgeons that can complete the surgery. But you need to find the best trained surgeon that also has the best laser eye surgery equipment and training.

Undergoing a Lasik eye surgery procedure can be performed in just a short span of time, a maximum of thirty minutes. This, however, does not cover the entire success of a Lasik surgery. It is also important to meet your chosen Lasik eye surgeon before and after the procedure. Prior to undergoing a Lasik surgery, you have to set an appointment with the Lasik surgeon who will evaluate you if you are an ideal candidate to undergo an eye surgery.

When you first meet with the Lasik eye surgeon, you will probably be told to stop wearing your contact lenses. You will be able to wear glasses, but contacts can change the shape of your cornea which might alter the results of your evaluation. You should ask the Lasik surgeon also about the risks and complications that can occur from having the Lasik eye surgery done during this time.

Most Lasik eye surgeries are performed in a chair much like a dentist would use. You will lay back and the surgeon will place drops in your eyes to numb them. Your eyes will then be cleaned and your eyelids will be held open. This is usually the most uncomfortable part of the Lasik procedure as our natural reflex is to close our eyes if something gets to close to them. Stay relaxed during this part, as much as you can, and it will be over before you know it.

There are different machines that each surgeon will use. Depending upon which machine the doctor uses, basically they are placed against your eye where the cornea is flapped to begin the procedure. The laser is then placed over your eye to begin the corrective part of the surgery.

Depending on how your procedure goes, it can be quick and with little discomfort for you to experience. It does sound scary with lasers and flaps being made, but there is really nothing to worry about. Once you have found a Lasik eye surgeon that you are comfortable with, most will take the extra time to reassure you and make it procedure as painless and comfortable as possible.

A cataract is a clouding of the eye’s natural lens, which lies behind the iris and the pupil. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eye’s focus, letting us see things clearly both up close and far away.

The lens is mostly made of water and protein. The protein is arranged in a precise way that keeps the lens clear and lets light pass through it. But as we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract, and over time, it may grow larger and cloud more of the lens, making it harder to see.

Researchers are gaining additional insights about what causes these specific types of proteins (crystallins) to cluster in abnormal ways to cause lens cloudiness and cataracts. One recent finding suggests that fragmented versions of these proteins bind with normal proteins, disrupting normal function.

One form of cataract is a cortical cataract, which forms in the lens cortex, gradually extends its spokes from the outside of the lens to the center. Many diabetics develop cortical cataracts.Third is subcapsular cataract begins at the back of the lens.

People with diabetes, high farsightedness, retinitis pigmentosa or those taking high doses of steroids run the risk of developing a subcapsular cataract. Congenital cataracts are known to be caused by infections women get during pregnancy, such as rubella.

Cataracts have also been connected with metabolic deficiencies such as galactosemia. Congenital cataracts risk factors include is inherited metabolic diseases, history of family or genetic cataracts, and also with infections due to pregnancy.

No one knows for sure why the eye’s lens changes as we age, forming cataracts. Researchers are gradually identifying factors that may cause cataracts – and information that may help to prevent them. Many studies suggest that exposure to ultraviolet light is associated with cataract development, so eyecare practitioners recommend wearing sunglasses and a wide-brimmed hat to lessen your exposure.

Other types of radiation may also be causes. For example, a 2005 study conducted in Iceland suggests that airline pilots have a higher risk of developing nuclear cataract than non-pilots and that the cause may be exposure to cosmic radiation. A similar theory suggests that astronauts, too, are at risk from cosmic radiation.

Think about surgery when your cataracts have progressed enough to seriously impair your vision and affect your daily life. Many people consider poor vision an inevitable fact of aging, but cataract surgery is a simple, relatively painless procedure to regain vision.
