How Laser Eye Surgery Works – Lasik and Photorefractive Eye Surgery

<h1>How Laser Eye Surgery Works – Lasik and Photorefractive Eye Surgery</h1>Author: <a title="Ricky Lim" href="http://www.articlesbase.com/authors/ricky-lim/88840.htm">Ricky Lim</a> People with eye-related problems are becoming more and more interested in laser eye surgery and its benefits because this is known to be the most exciting ophthalmologic procedure. To be more precise, this is a refractive eye surgery that can correct all types of refractive errors such as: astigmatism (distorted vision), myopia (nearsightedness) and hyperopia (farsightedness). Even if the medicine offers various types of surgical techniques for correcting refractive errors, the laser eye surgery was labelled by the American Academy of Ophthalmology the most technically advanced and precise one. The excimer laser was the first laser ever approved for eye surgery and it’s used to correct myopia. Now, this laser is used in two different procedures: Laser in situ Keratomileusis (LASIK) and Photorefractive Keratectomy (PRK). Photorefractive Keratectomy (PRK) The surgeon maps and measures the patient’s eye before the procedure in order to analyse the problem. Then, he uses a few local anesthetic eye drops and reshapes the cornea eliminating tiny amounts of tissue from the outer surface. Next, the doctor uses an ultra violet beam of light and cuts notches the size of human hair. Each pulse of light can remove a 39 millionth of an inch of cornel tissue in only 12 billionths of a second. According to same studies, only 5% of the patients still use permanent glasses after the surgery while 15% need visual aids only when driving. Laser in situ Keratomileusis (LASIK) The LASIK procedure is more complicated than PRK but it’s a solution for solving all types of myopia. The surgeon uses the Microkeratome to cut a corneal tissue flap in order to replace it. Everything depends on the doctor because with LASIK he has to make a very precise incision. The patient only feels a little discomfort and sometimes an irritation but those won’t last too long. In most cases, the patients returned to their normal life in only two or three days. With LASIK there can be only one side effect and that is occasional glare at night. Anyway, everyone should know that even if the results are said to be permanent, the age can influence the final results and in some cases the doctor may even suggested re-surgery.

People with eye-related problems are becoming more and more interested in laser eye surgery and its benefits because this is known to be the most exciting ophthalmologic procedure.

To be more precise, this is a refractive eye surgery that can correct all types of refractive errors such as: astigmatism (distorted vision), myopia (nearsightedness) and hyperopia (farsightedness).

Even if the medicine offers various types of surgical techniques for correcting refractive errors, the laser eye surgery was labelled by the American Academy of Ophthalmology the most technically advanced and precise one.

The excimer laser was the first laser ever approved for eye surgery and it’s used to correct myopia. Now, this laser is used in two different procedures: Laser in situ Keratomileusis (LASIK) and Photorefractive Keratectomy (PRK).

Photorefractive Keratectomy (PRK)

The surgeon maps and measures the patient’s eye before the procedure in order to analyse the problem. Then, he uses a few local anesthetic eye drops and reshapes the cornea eliminating tiny amounts of tissue from the outer surface.

Next, the doctor uses an ultra violet beam of light and cuts notches the size of human hair. Each pulse of light can remove a 39 millionth of an inch of cornel tissue in only 12 billionths of a second.

According to same studies, only 5% of the patients still use permanent glasses after the surgery while 15% need visual aids only when driving.

Laser in situ Keratomileusis (LASIK)

The LASIK procedure is more complicated than PRK but it’s a solution for solving all types of myopia.

The surgeon uses the Microkeratome to cut a corneal tissue flap in order to replace it. Everything depends on the doctor because with LASIK he has to make a very precise incision.

The patient only feels a little discomfort and sometimes an irritation but those won’t last too long. In most cases, the patients returned to their normal life in only two or three days.
