People who are now suffering from myopia and hyperopia can choose to receive lasik eye surgery if they want to have perfect vision. And facts have also disclosed that many people in US have benefited from it. However, before getting the surgery, people are suggested to consult with their physicians.
But there is a bad news for some people- some of them can not receive this surgery. Usually, people with presbyopia- an age related vision problem- can not receive this surgery. This is mainly because the cause for the problem is a biological process. And they may have other options.
Usually, a qualified candidate should meet the following requirements. 1. Their eyes should be suitable for the surgery.2. Pregnant women can not get it 3. No adult can get it, or some should be at least 21. 4. People should have stable vision, or the surgery can not be operated. 5. People with some particular physical diseases can not get it- like immune disorders, rheumatoid arthritis, etc.
In fact, according to their specific conditions, people can choose different laser eye surgery. Here are some of them. PRK, a traditional surgery, can be used to cure myopia and hyperopia. In the surgery, some UV lights will be used to reshape the corneas. And sometime will be used to recover, and some complications can not be avoided.
LASIK eye surgery is another very famous one, abbreviation of situ keratomileusis. During this process, a cut will be made on the cover of the cornea. And the laser will be operated onto the inner tissues in the cornea. Of course, patients will feel no evident pain and enjoy very nice eye sight.
And during another sort of LASIK surgery, no cut will be made on the cornea. The main equipment will be used is computer and lasers. This is to some extent similar as PRK. It can help people who are struck by night glares and halo complications. Accuracy is one of the greatest advantages in this surgery, for every step is computed by the computer.
Generally, six people in ten of those receivers can have 20/20 vision or more. And nine will get 20/40 vision. This is one of the greatest reasons why so many love to get it. During this process, only half an hour will be used and patients can go home immediately. But there is a problem that the cost is averaged about two thousands dollars for each eye with no insurance coverage. Anyway, before the surgery, consult with the eye doctors.
