In response to the question "how laser eye surgery works?" I'd like to point out that there are a number of surgical options.

Many people know only about LASIK surgery because it is the one most talked about and most popular.

However eye surgeries also include LASEK, also known as Epiflap, PRK, LTK and many others and depending on your eyes, one may be better than the others.

How Laser Eye Surgery Works in General?

Laser eye surgery is a new advance in surgical procedures that takes away the dependence on glasses.

Laser eye surgery, in general, works by using a laser aimed at the cornea; the cornea is the clear structure covering the iris (the colored part that surrounds the pupil). The laser works by lessening the thickness of the cornea so that the eye is able to bring images into focus.

LASIK eye surgery

LASIK eye surgery is one of the newest forms of eye surgeries and works by slicing a thin layer of the cornea off so it forms a flap so the laser can target the tissue underneath.

The flap is then put back to where it was sliced from, and the body naturally repairs it causing vision to be improved almost instantly. Lasek or Epiflap eye surgery

These treatments involve partially removing the epithelium, the outer layers of the cells on the eye, so the cornea is revealed. A laser then reshapes the cornea; the eye is bought back to its normal position where it repairs within days.

PRK, Photorefractive Keratectomy

Is a laser surgery that will successfully treat nearsightedness, mild farsightedness, and some astigmatism problems. This procedure is quick, taking less than one minute for each eye. There is no flap cut into the eye as there is with LASIK surgery.

LTK

Is a procedure used to treat farsightedness and astigmatism. During LTK laser eye surgery, a laser beam uses heat to shrink and reshape the cornea. Vision problems from farsightedness or astigmatism are corrected in a matter of seconds, without any cutting or removal of tissue.

LTK highly effective in the short-term, however the results of LTK laser eye surgery are not permanent. Vision gradually regresses following LTK laser eye surgery, mostly in the three months following surgery. Taking this into account the doctor will intentionally overcorrect, so that after the three months, you end up with the vision desired.

All-Laser LASIK surgery uses an extra laser beam instead of a blade in cutting the flap in the front of the eye to correct the problem. After the flap is lifted, then the second laser beam corrects and reshapes the eye.

As mentioned previously, these are only some of the eye surgeries that are available.

The future of laser eye surgery

Laser eye surgery keeps improving all the time, with advances in technology happening constantly in medicine it is only a matter of time before a new, improved surgery is found.

If you have been thinking about improving your eyesight through laser eye surgery it may be worth reading more information about the different surgeries and finding recommended consultants in your area who carry out the procedure before deciding it is definitely what you want.
