How Lasik Surgery Can Benefit You

LASIK or Laser-assisted in situ keratomileusis, commonly known as LASIK, or simply lasik surgery, is an advanced form of refractive keratectomy for the treatment of hyperopia, myopia, and astigmatism in eye surgery patients. A ribbon-like flap, called a corneal flap, is opened with the use of a laser to remove the external layer of corneal tissue (keratome) and replace it with a thin, flexible band of tissue. The new corneal tissue is designed to work like your own natural lens. It has the ability to bend light in the direction you desire – up and down, left and right, even up and down – similar to a pair of glasses. In addition to providing much better vision than your natural lenses, the corneal flap can also prevent painful and embarrassing eye dryness that frequently occurs after surgery.

Although the results of lasik surgery may be very good, there are certain situations where the vision may still be blurry after surgery. In some cases, a patient may have problems meeting close-up objects such as letters or small print. This is because the flap is open at the bottom, exposing the clear corneal layer; however, when the flap is closed, the object appears blurred because the inside of the eye is now covered by the thin, misshapen corneal layer. Because some people have a problem meeting objects, they may still need to wear reading glasses to help them see clearly after lasik surgery.

Many people report having dry eyes at first, but within the first six months of lasik surgery, their eyes may feel a little dry for a few days. To promote healing, the top of the lens should be covered with a sterile solution of 1% hydrocortisone cream, which lubricates the cornea and prevents irritation. As with any surgery, dry eyes can be aggravating, so it’s important to take the first six months very seriously. With proper care and attention, the results of lasik surgery can last a lifetime.
