User:Ravenclaz/Thinking of laser eye surgery

Laser Eye Surgery is a surgical procedure used to correct myopia, and hyperopia. In this procedure cornea is operated, and it only takes few minutes depending upon state of health of eyes. In Laser eye surgery procedure an high quality precision ray of light through microscope is used called Excimer, used to carve corneal tissues of eye to help light rays refract correctly on retina of eye.

There are basically two different types of laser eye surgeries PRK Laser eye surgery and LASIK laser eye surgery. Under these two categories there are many modification available for each type. LASEK laser eye surgery is new type of PRK laser eye surgery.

PRK Laser eye surgery in this surgery to remove the epithelium cornea's outermost layer, surface ablation technique is used, and excimer reshapes tissues located on the underlying surface of cornea. LASIK Laser eye surgery is a procedure in which a thin flap of tissue is cut, and then peeled back from front of the cornea (the transparent covering over pupil). The corneal tissue below the flap is vaporised using the laser to reshape the cornea to correct the refractive error. Then flap is placed back over front of eye.

LASEK Laser eye surgery is the latest upgraded version of PRK Laser eye surgery also know as "PRK epiflap" or "Advance Surface Ablation". The difference is in PRK laser eye surgery the epithelium is surfaced, instead in LASEK Laser eye surgery the epithelium is removed with a drop of weak alcohol solution, the laser applied before and epithelium is replaced back onto the eye and held in place with a contact lens.The Contact lens is later removed after few days.

Precautions Like every other surgery, the Laser eye surgery is also not for everyone. In order to confirm its necessity consult a laser eye surgeon and find out whether it is suggested to perform or whether the vision can be corrected for the present condition of eyes. The thing is laser eye surgery is not performed on anyone until the 'eye degree' of the individual has stopped varying. Often as we grow old, our eyes achieve a state and last for some time, which is the best suited time to undergo laser eye surgery procedure.
