Things You Should Know Before Lasik Eye Surgery

If you are one of the patients who have eye problems such as nearsightedness, farsightedness, or astigmatism, you may probably have considered undergoing a refractive laser eye surgery to improve your vision so that you never need to wear glasses or contact lenses any more. Before you actually do lasik eye surgery, there are many things that you should know.

First of all, you should have an eye exam in a licensed eye clinic to see if you are a candidate for lasik eye surgery. If the patients’ vision is not stable, they will not be a suitable candidate for lasik eye surgery. This is also the reason why people under 21 years old or those whose hormones are fluctuating are recommended not to have lasik or any other kind of refractive eye surgery performed. There is about 6% of the American population who have carried out laser eye surgery may have a not favorable result. Some of them may need another eye surgery, but it is not advisable to proceed. Besides, patients who are pregnant or have weakened immune systems are also on the name list of unsuitable people for laser eye surgery. And the patients’ health history, especially any eye injuries or eye diseases, should also provide to the eye doctor to help him judge if you are suitable to undergo the eye surgery.

Then you should discuss the procedure of the eye surgery with your eye surgeon to find a best lasik eye surgery for yourself. For instance, what kind of eye surgery will be performed? Which instrument or laser techniques will be used? It is also important to know the possible complications of the lasik eye surgery sufficiently.

Finally, you should know the cost of each kind of eye surgery. It commonly varies greatly depending on the instrument, techniques, eye doctor, and eye clinic you choose and the condition of your eyes.

You may find the information on the internet or from any local eye clinic.

How a Cataract Surgery Is Done

Cataract is the clouding of the lens of the eyes. It affects vision. A thin lining of cloudy natural lens is removed from the eye because it blocks the passage of light. This is how a cataract surgery is done. Cataract surgery is a harmless procedure. Every year, there are more than 1.6 Americans who undergo this treatment to repair their vision. More than half of the American population have cataract or may have been through a cataract surgery by the age of 80. Some people believe that when one eye has cataract, the other eye will definitely be next. This is a myth. Cataract doesn’t spread. It can occur in either or both eyes though.

On the day of the surgery itself, there is a list of things to do such skipping breakfast and avoiding intake of liquids. An eye drop to dilate pupils and sedative are given prior to the actual procedure. Topical anesthesia is also given in order for the patient not to feel the pain. After the areas around the eyes were completely cleansed and after a sterile covering is put into place, at least a small cut is done into the eye to enable the surgeon to remove the cloudy lens. There are two methods to remove the cloudy lens. One is through sonically breaking up the cataract then extracted out of the eye. The other one is through mechanically breaking up the cataract into small pieces then removed from the eye through a small incision. After this, a plastic or silicon intraocular lens will replace the natural lens that was taken off the eye.

 

After the operation, a protective shield is placed on the eye. Then the patient is usually sent home after few minutes in the recovery room. Surgeons advise patients to apply eye drops for a number of times in a day. This goes on for few weeks depending on the surgeon’s advice. Just like any other medical procedure, there are dos and don’ts patients are given to ensure effectiveness of the operation.

 

The price of a cataract surgery is around $3,000, exclusive of health insurance. Fortunately, HMOs, Medicare and other health insurances cover this specific surgery. It is indeed pricey however, the American Society of Cataract and Refractive Surgery reports 98% of the patients believe it is highly recommended since it simply worked for them.
