How Is Refractive Surgery Done?

Refractive surgery is cosmetic eye surgery designed to correct the vision for a variety of visual impairments, including presbyopia (nearsightedness), hyperopia (farsightedness) and astigmatism (hypermetropia). Refractive eye surgery involves various procedures of surgical remodeling or replacement of the natural cornea to correct an optical disorder such as presbyopia or astigmatism. Some of these procedures include LASEK (light energy polarized light excimer laser) surgery, iridotomy, several screw implant, C-diff laser surgery, laser resurfacing, and photoepi-lasik.

Refractive eye surgery can be performed in either a doctor's office or in a hospital. The surgeon will first analyze your eyes and make sure you have a history of safe refractive procedures. Then he will order the necessary tests, which will determine the appropriate procedure for your eyes. He will make sure your eyes are healthy before performing surgery, and he will use special equipment to give your eyes a thorough examination prior to surgery.

After the diagnosis has been made, the surgeon will then create a plan for you to correct your vision. You can choose from several different procedures depending on your visual impairment and other factors such as age. The most common procedures include:

LASIK - In LASIK, a small laser is used to reshape the corneal flap. The flap is opened on one side of your eye and a thin, clear layer of tissue is placed over it so the cornea is reshaped, which improves the shape of your eye. This procedure can also correct nearsightedness, farsightedness and astigmatism, but it is only effective for people with ideal vision and perfect corneal topography.

LASEK - In laser eye surgery, a thin layer of plastic is placed on the corneal flap, while your eye is being cleaned and prepared for surgery. As the plastic is heated to a certain temperature, the plastic becomes transparent. Laser energy is used to heat the plastic layer, allowing it to heat up and melt the outer layer of the corneal flap, which creates a new corneal layer that looks just like the original corneal flap. and is just as transparent as the original corneal layer. This procedure also works to correct a variety of other conditions such as nearsightedness, farsightedness and astigmatism.

IRT - In iridotomy, the iris is gently moved into place by placing a tiny metal bar in the iris to allow the eye to open. open to a small distance and then removing excess skin and stroma to make room for the iris. The surgery will not affect the iris. A laser is then used to reshape the corneal flap to fit the iris. A metal tube called the trabecular meshwork, or trabecular mesh, will be inserted in the middle of the iris to hold the iris in place after the surgery.Chick here for more details about chirurgia refrattiva
