LASIK is a refractive eye surgery. Becomes your dependence on glasses or contact lenses, correcting their nearsightedness, hyperopia, or astigmatismoa to disminuar. It is possible that it is both eyes at the same time, and then you have clear vision. But how this surgery? This article explains the procedure and the LASIK technology. To understand the LASIK surgery, it is necessary that you understand how the eyes work. The eyes function as a camera: have lenses or Crystal that they refract the light reflected from objects and focus it, but instead of camera film, eye retinas are used.

Retinas interpret the image and send it to the brain via the optical nerves. Under the conditions of myopia, hyperopia, and astigmatismoa, the Crystal can not focus light on the retinae. Lenses or contact lenses change the light before she enters the eyes. But LASIK manipulates the surface of the eyes so that they can focus the light properly. LASIK surgery consists of three parts: 1. first, creates a flap in the surface of the eye 2. Second, a laser reform corneal 3. Three, it reset the tab for recovery at all, the procidiemento lasta minutes.

It is necessary that recovers for two or three days, but most LASIK patients can see clearly in the morning after surgery. An advance of amazing technology in the past, an instrument called a microkeratome, a very thin blade mechanical, corneal flap creates. There is now a new laser that can create the flip. Intralase is called. Intralase is a Visita infrared laser. In other words, uses very short light pulses: one quadrillionth of a second. Such brevity allows precision more than other lasers used in LASIK surgery. Sometimes, this laser is better to create the flap, but is necessary to consider the advantages and disadvantages to both instruments. The microkeratome is more comfortable because: Recovery is faster There is less pain The procedure is shorter It is more barrato but Intralase has many advantages too, including: Creating tabs in the corneas too thin for a microkeratome Less risk of complications If there are complications in creating the tab, it is possible to try again in an hour while it is necessary to wait for three months with a microkeratome both technologies work well to create the flap. Consult your refractive surgeon to choose what is best for you. Anyway, LASIK is one of the safest surgeries performed and the rate of complications with any instrument is small mu.
