What is Laser Eye Surgery?

Refractive state of eye is enhanced through later eye surgery so that reliance on glasses or contact lenses is reduced. With later surgery the cornea is remodeled and the shape of cornea is permanently changed. Latest development in this field is LASIK (Laser Assisted In-Situ Keratomileusis). An instrument known as microkeratome is used to cut flap of the corneal tissue to enter into the cornea. Nearsightedness is typically corrected through this procedure. Laser eye surgery is a common method used in surgery. An excimer laser is used to ablate some tissue from frontage of the eye. Latest technique akin to LASEK is EPI-LASIK where epi-keratome instrument is used to take out top layer of cornea. Under local anesthesia PRK (photo refractive keratectomy) procedure is performed. The eyes are anesthetized with the use of eye drops. Microscopic amounts of outer eye tissues are destroyed through this type of refractive surgery. With the use of computer controlled UV light the cornea is reshaped.

In recent years, Laser eye surgery refractive surgery has become very common and popular. This is, however, not recommended to those afflicted with glaucoma or diabetes or in case of slow healers. It is also not advised to those suffering from vascular diseases, pregnant women and autoimmune diseases. In case of other normal healthy individuals also, certain amount of risk is always involved. There could be delay in healing or they could be exposed to exposure. With right treatment, this problem can be over-come in the long run. Some other typical complaints associated with Laser eye surgery include regression and halo effect.
