The Eye And Laser Eye Surgery

Functional Eye (refractive error) The eye is a visual organ. It is used for everything we do, from exercise to reading. Normal and functioning eyes can focus on short and long objects and images, perceive the depth, and adapt to light changes. Depth perception is due to the fact that the two separate eyes produce two separate images and the ability to adapt to light changes is due to the iris and the expanding muscle. However, these two aspects of the eye do not involve laser eye surgery and will not be discussed in the literature.

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.

During LASIK eye surgery, the ophthalmologist forms a flap (A) in the cornea. This is the surface of a transparent domed eye that occupies the majority of the curvature and frequency of the eyes. The surgeon then uses the laser (B) to reform the cornea, which corrects the refractive problem of the eye (C). LASIK (laser assisted in situ corneal transplantation) is a laser refractive surgery - the most famous and the most common procedure. In general, a special type of cutting laser is used to accurately change the shape of the cornea - the transparent tissue of the dome shape in front of the eye.

There are various kinds of laser eye surgery. Lasik - Laser assist in situ corneal transplantation - the most common type. Many of Lasik 's patients eventually have 20/20 eyesight. However, as with all other medical procedures, it is both dangerous and informative. Only your ophthalmologist can judge whether you are suitable for laser eye surgery

LASIK eye surgery is the most common laser eye surgery. LASIK is an abbreviation for "Laser In Situ Keratomileusis". This procedure is used to correct various refraction problems that people must always wear contact lenses and eyeglasses. Anyone with myopia or hyperopia can receive Lasik surgery and correct eyesight. With the aid of a laser, put a slight cut in the cornea, make it flat (in the case of short vision) or otherwise bend (in case of hyperopia). Using anesthesia before surgery makes it a completely painless experience. LASIK eye surgery has various forms. Some of them are described below.
