Who can have a Lasik eye surgery?

Not everyone can have this type of surgery. First of all even if you meet all the requirements you will have to be examined from the doctor who will measure the thickness of your cornea, the refraction, the air pressure and the overall cornea mapping. One of the defining factors of weather you can have a Lasik eye surgery or not will be the actual thichness of your cornea which is not the same for every person. If it is not thick enough it is up to the doctor to decide which type of Laser surgery is best for you, for example PRK laser surgery is often used for people who have less thick cornea. In any case there are a number of requirements that you need to meet in order to perform any type of laser eye surgery:

· You must be at least 20 years old and have a stable vision for at least a year. That means that your prescription for glasses must be stable because there is no point to perform a surgery if your prescription is not stable and the refractive error keeps changing, as you would need another surgery pretty soon.

· You must be healthy and not suffer any kind of chronic medical condition, in other words your body must have the ability to heal quickly and efficiently.

· If you are a woman you must be sure that you are not pregnant.

· You must not be diabetic or suffer of any kind of collage / vascular desease.

· You should not expect 100% perfect vision after the surgery, you should always first talk with the doctor who will inform you what results you should expect accordingly to your degree of your prescription.

Is lasik eye surgery effective for presbyopia?

Presbyopia is related with aging and it is caused when the lens of the eye become hard and less flexible. The lens can no longer change their shape effectively to focus on closer images because although the muscle constricts the lens is not elastic enough to form the correct shape.

Lasik correction for presbyopia is tricky because one eye is treated to have near perfect distant vision while the other eye is treated to have near perfect close distant vision. This means that in any given time one eye is out of focus, however the brain has the ability to automatically select the image that you prefer to focus on which is the best image. This type of vision is called monovision and you should ask from your doctor to give you the opportunity to try it out by wearing appropriate glasses before you make up your mind if you want to perform Lasik surgery for your presbyopia or not.
