Laser Eye Surgery Gives Wonderful Vision To Anyone Who Has 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.
When surgery is begun pain medication is put right into the eye. After a few minutes tape is used to keep the eyes open and then a speculum is inserted to force the lids to separate. A tiny cut is made on the cornea so a flap can be created. The laser moves in and takes out the excess cornea material. The little flap is then put back in place and stitched. The whole procedure only takes a few minutes and the pain is minimal. There is little chance of a mistake because the laser is programmed and moves automatically.
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.
Laser eye surgery is major surgery and should not be taken lightly. There are many preparations that must be done such as avoid wearing contact lenses for a period of time before the surgery and eye make up must be avoided. Depending on the type of lenses you wear it could be several weeks of preparation. After surgery eye makeup needs to be avoided for a period of time and you must wear an eye guard when you sleep. Eye drops need to be administered and antibiotics taken. It might take awhile to be able to see well after surgery but in most cases vision is improved right away and about 90 percent of those that have surgery are successful at having perfect vision without the aid of glasses or contacts.
