How Laser Technology Improve Your Eyesight

The advancement of technology in recent time has brought about many changes in the medical science field. A clear and simple example of such improved technology is laser eye surgery. Laser eye surgery is becoming a highly popular method of correcting eye problems. More and more people are going in for laser eye surgery all over the world, as it is considered to be safe and highly productive.

How exactly does the laser correct the vision problems? Through a laser vision apparatus and control method, short beams of invisible lasers take out minute tissue samples from the cornea to properly align the curvature. The tissue is so miniscule that it’s actually less thick than a strand of human hair. By removing this tissue, the retina is able to focus on the images better and so the images become clearer.

What are the types? There are generally two types: PRK or photorefractive keratectomy and Lasik or laser-assisted in situ keratomileusis. Under these umbrella terms, several other procedures are categorized. PRK is a procedure that uses an excimer laser that removes the outer layer of the cornea, which is then reshaped to correct the eye disorder. Lasik is another refractive procedure that uses a surgical instrument to create a flap under the cornea. This flap is then lifted after which the laser reshapes the cornea.

Who are good candidates for laser eye surgery? People over 21 years of age are good candidates for laser eye surgery. They must not have severe eye disorders such as glaucoma. A visit to an eye specialist can help the patient determine if this is the best way to correct your myopia, hyperopia or astigmatism.

How safe is the procedure? People all over the world have had laser vision correction surgery successfully performed on them. Laser surgery is very safe, takes less than ten minutes on the whole and patients may expect full recovery in a matter of days.

How much is laser eye surgery? The usual cost for it is about $ 1,500 dollars per eye. This covers pre-operative and post-operative visits as well.
