Laser Refractive Surgery
Laser refractive surgery is defined as surgery that corrects the acuity of vision, with the aim of reducing or eliminating the need for glasses and contacts. Included in the laser refractive surgery list are radial keratotomy, PRK, LASIK, and corneal implants. This also refers to the removal and replacement of the lens of the yes, the reshaping of corneas through incisions, reshaping of the corneas with incisions and laser, as well as the reshaping of the corneas with prosthetic inserts, as well as implantation of lenses.
Briefly, here are the different kinds of refractive surgical procedures.
* The Laser-assisted in Situ Keratomileusis (LASIK), in this procedure a flap is created in the stroma, after which the eye doctor then uses the excimer laser to remove material under the flap.
* The Laser Epithelial Keratomileusis (LASEK) is similar to LASIK, except that the flap is created in the epithelium only, instead of through the epithelium and part of the stroma.
* The Epi-LASIK is like LASEK in that the flap is cut only in the epithelium; however, the eye surgeon uses a separator called an epikeratome, to create an epithelial sheet.
* The Photorefractive Keratectomy (PRK) procedure is where the eye doctor will use a laser to remove tissue from the surface of the cornea, with the result that the cornea has a new shape, thus reducing the vision problem.
* The Radial Keratotomy (RK) procedure is where the eye doctor makes incisions in a radial (spoke-like) pattern in your cornea, with the aim of flattening it, to reduce nearsightedness.
* The Astigmatic Keratotomy (AK) is the preferred laser refractive surgery wherein the eye doctor will cut the corneas in areas that are too bulgy. To flatten them to a more regular curve.
