Laser Eye Surgery Provides Spot On Eyesight To Individuals Who Need To Wear Glasses

Laser eye surgery is also referred to as LASIK surgery

. This type of surgery makes it possible for those who normally have blurry vision to be able to see again without wearing contacts or glasses. The surgery was brought to the public in 1990 and is very popular today.

Laser surgery is possible for those that have certain eye problems. Those with near sightedness and far sightedness are in luck because they qualify. When the eyes work correctly light pours through the lens of the eye and on to the retina where the light bends or refracts. The retina is what makes things focus within the sight system. People that have problems with vision have a problem with the light refracting on the retina. For many reasons the light does not get that far or goes too far. When you wear corrective lenses it causes the light to once again fall on the retina to focus.

A person that cannot see far has an issue with the light falling short of the retina and instead it falls on the cornea. All laser surgery requires is that the cornea be reshaped so that the light can refract on the retina. In the case above the laser removes material in the middle of the cornea, which becomes thinner and no longer stops the light from getting to the retina. Those having the opposite problem of not being able to see up close also has part of the cornea removed with the laser Instead of the middle material the laser cuts away from the edge of the cornea so that the light no longer over shoots the retina.

A patient is given a painkiller that is applied to the cornea of the eye before surgery. The eyelids are taped open and a metal tool called a speculum is applied to keep the eyelids apart. The surgeon makes a small makes a small cut on the cornea that creates a flap. The laser then removes the material from the cornea that makes it impossible for the light to focus in the correct area. The flap is put back where it belongs and stitched back into place. The procedure does not take long and though there may be some discomfort there is not any extreme pain involved. The laser is pre programmed and automated so there is little chance that there can be any mistakes.

Only those people whose eyesight has been relatively the same for a long period of time are appropriate for the surgery, which generally leaves out patients that are very young. There may be some problems with those people that have a thin cornea. If there is not enough material to remove to reposition the focus, the procedure cannot be done. Most of the time these are patients that have very bad eyesight. People with astigmatism or presbyopia (relating to age vision conditions) are usually appropriate for the procedure.

Health insurance usually will not pay for laser surgery. There are those doctors that will accept payments but most want to be paid the entire amount before surgery commences. Make sure to find a doctor that has done many surgeries. Do not go to a doctor that advertises a cheap rate and has not done many surgeries. Laser surgery will cost about USD $1500 at the least and $3500 at the most so watch out for added expenses after surgery by a doctor charging less.

This type of surgery is major surgery. It will take some preparation to have it and if you wear contacts you will not be allowed to wear them for a while prior to surgery. This may be just a few days or up to a month or so. Afterwards eye makeup must be avoided and a guard is placed over the eye to protect it while sleeping. There are drops to be put in the eye periodically to prevent dry eye and a chance that you may have to take an antibiotic to prevent an infection. Some people see relatively well right after surgery but it might take some time with others however, approximately ninety percent of people having laser eye surgery are able to see clearly without having to wear corrective lenses.
