Laser Eye Surgery Delivers Perfect Sight To Those Who Need To Wear Spectacles

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.

An eye afflicted with myopia does not work that way. The light that goes into the eye refracts onto the cornea instead of the retina. In laser surgery the cornea is reshaped to make the focus function return to the retina. Some of the eye material in the center of the cornea is removed so that it becomes thinner and enables the light to get to the retina. In those with hypermetropia light is refracted but is not able to reach the retina. Instead of taking material out of the middle of the cornea, material from the edges is removed.

When surgery is performed pain medication is given to the patient being put directly on the cornea. Tape is used to stop the eye lids from shutting and a speculum is screwed on to make sure the eye lids never close during surgery. A cut is made in the corner to make a small flap. Then the laser moves in to remove material from the cornea. Once that is done the flap is replaced and it is all over. It only takes a few minutes to perform the procedure and the only thing the patient might feel is a bit of discomfort. The laser is automated and the perimeters are entered into it prior to surgery so there is very little chance anything can go wrong.

A person who has had the same eyesight for a long period of time is a perfect person for the surgery. Usually young people's prescriptions change frequently so they might not be able to get the surgery. A person with a thinner than average cornea cannot have the surgery either because removing material from a thin cornea can damage it permanently. Those with the vision loss due to age called presbyopia and those with an astigmatism can have the surgery done.

In most cases laser surgery is not covered by health insurance. Some doctors will allow payments while others will only take a lump sum before the surgery is completed. It is important to pick a doctor that has a good track record in doing the surgery. It is not advisable to use a doctor that charges less but has less experience in this procedure. Most costs run from USD$1500 upwards to about $3000 and anyone who advertises cheaper rates usually add on other charges later.

This is considered major surgery and be prepared to have to do certain things before and after surgery. Those that wear contacts have to stop wearing them for a period of time and those that have hard lenses may have to wait a few months. Eye makeup must not be worn several days prior and a week or so after surgery. Eye drops will have to be taken after surgery and an antibiotic must be taken as well to stop any infection that may develop. There is a special guard to put over the eye when sleeping in order to protect it. The good news is that 90% of those that have the procedure can live the rest of their life being able to see perfectly without wearing corrective lenses.
