people with problems related to the eye are increasingly interested in laser eye surgery and its benefits because it is known that this is the most exciting ophthalmologic procedure.
To be more precise, it 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 drug offers several types of surgical techniques for correction of refractive errors, laser eye surgery was labeled by the American Academy of Ophthalmology of the most technically advanced and accurate one.
The laser excimer laser was first approved for eye surgery and ITA?? s used to correct nearsightedness. 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 of the patient? ??? s eye before the procedure to analyze the problem. Then he uses a few local anesthetic eye drops and reshapes the cornea by removing small amounts of tissue from the outer surface. Then the doctor uses an ultraviolet beam of light and cuts the notches on the size of a human hair. Each light pulse can remove 39 millionths of an inch of cornel tissue in just 12 billionths of a second. According to these studies, only 5% of patients still wear glasses after surgery permanent, while 15% need visual aids only when driving. laser in situ keratomileusis (LASIK) The LASIK procedure is more complicated than PRK but Ita???? sa solution to solve all types of myopia. The surgeon uses the microkeratome to cut a flap of corneal tissue in order to replace it. Everything depends on the doctor, as with LASIK have to make a precise incision. The patient only feels a little discomfort and sometimes a rash but Wona?? t last too long. In most cases, patients returned to their normal life in just two or three days. LASIK can not be just a side effect and is occasionally glow at night. Anyway, everyone should know that even if the results are said to be permanent, age can influence the final results and in some cases the doctor may even suggested back surgery.
