Laser Eye Surgery Information

Refractive Laser Surgery: A thorough understanding of LASIK 's refractive correction laser surgery provides nearly perfect sight, and God gives people who are tired of wearing glasses. As popularity grows, it is worth understanding more about Lasik and understanding what this magic surgery needs. Refractive laser surgery is a procedure that corrects the refractive index of the eye to reduce the need for glasses or contact lenses. It corrects vision problems such as myopia, myopia, hyperopia, hyperopia, and astigmatism that the cornea can not focus sharp images on the cornea.

Refractive keratectomy (PRK) is a laser eye surgery first introduced in 1986, 13 years ago when the FDA approved LASIK. Like other commonly used laser eye surgery, PRK reforms the cornea and uses an excimer laser to correct myopia, hyperopia and astigmatism. Unlike LASIK (which creates a flap in the outer layer of the cornea), PRK surgically removes the thin surface of the epithelium and cornea to change the shape of the cornea. This approach eliminates the risk of complications of the flap and reduces the risk of removing too much cornea. Most patients will benefit from custom PRK. It uses customized wavefront technology to give your surgeon more level of data about your vision requirements.

The ophthalmologist uses a femtosecond laser or mechanical cutting instrument (micro keratome) for LASIK eye surgery to create a circular valve on the outer layer of the cornea. The newly exposed underlying corneal tissue is then reshaped with an excimer laser. The flap returns to its original position and functions as a natural "bandage". This procedure lasts about 10 minutes per eye, and the recovery time can be several days to several weeks. Learn how to learn what happened during surgery. Full laser LASIK is called Bladeless LASIK because the mechanical cutting tool used to create a circular flap in the outer layer of the cornea is replaced by a femtosecond laser. Recent improvements in microkeratome made blade LASIK safer, but bladeless LASIK has less complexity than usual.

I am receiving laser eye surgery called PRK. Currently in the United States there are two general laser treatments PRK and LASIK. The latter is actually more popular. Because the healing time is faster thanks to the way the program is done. PRK involves removing a portion of the cornea using an excimer laser to reform the surface. On the other hand, LASIK creates a "flap" from the cornea, which is used for laser stripping and then returned for treatment. You can read more about the differences here.
