Laser Eye Surgery is a process used to correct visual problems. This is carried out through the use of an excimer laser. The process is highly effective and not overly complicated, and is generally a better alternative to a conventional eye operation. It is a procedure that is used especially to treat problems related to refractive errors. The process involves the use of a laser beam appropriate for visual correction. Those who are diagnosed with myopia, hyperopia, and astigmatism are prime candidates for laser eye surgery. It is a reliable alternative for those who wear eyeglasses and contact lenses.

Laser Eye Surgery
Several types of laser eye surgery are available, including LASIK, LASEK, and PRK. In order to prepare properly for the operation, it will be necessary for a doctor to properly examine the eye problem prior to the procedure. The appropriate procedure will be decided upon by the ophthalmologist. The decision will be based on examination of the existing vision problem, risk factors, and affordability. Some preparatory steps should be undertaken prior to the operation.
The most common form of laser eye surgery is Laser Assisted in Situ Keratomileusis, also known as LASIK. During this procedure, the patient will be given anesthetic eye drops and sedatives. The eye will then be immobilized, before a flap is made in the cornea. A mechanical microkeratome will be used to perform this operation. The flap will then be folded, in order to allow access to the middle portion of the cornea. The excimer laser will be used to reshape the cornea. Vision should improve within a few weeks of surgery.
LASEK eye surgery, also known as Laser Assisted Sub-Epithelial Keratomileusis, is similar in its makeup to the PRK process. With the LASEK process, an alcoholic formulation is used before the outermost layer of the cornea is scrapped. This allows for the softening of this layer, which can then be removed gently. The stroma is then reshaped with the excimer laser, before the epithelium is then replaced.
The PRK process is normally appropriate for those with a relatively thin cornea. PRK stands for Photorefractive Keratectomy, and involves the manual scrapping of the outer layer of the cornea. The excimer laser is then used to reshape the stromal layer of the cornea. There is a slightly longer period of recovery with this type of operation. Some self care tips are given in order to help the patient speed up the healing process.
