Refractive Surgery

Before doing any surgery, you should always understand and know what is going on.

With all the new procedures, where, in order to reduce dependence on glasses, how to select one, do not even know what they mean? 101 welcome refractive surgery.

In RK (radial keratotomy) - the first and most popular form of the first refractive surgery (surgery, in order to reduce dependence on glasses, by Ortho-K and effectiveness of your prescription glasses, while on the surface of your eyes) . Cuts in the cornea to relax its curvature, thereby changing it. With the passage of time, its effect is not stable, and in some patients because of the procedures used. A very small number of physicians, surgeons, now performed in the RK, because of this point.

Have PRK (photorefractive keratectomy operation) - the top of a very thin cornea (epithelial), is to eliminate all kinds of methods, including alcohol, brushes, or laser. Laser, and then reshapes the cornea very sophisticated, resulting in a more predictable and stable results. Top, and then left renewable itself over 3 - 7 days. Patients wear the "bandage" contact lens, in the meantime, to comfort. The vision of the progress of the recovery is slower than expected, with the LASIK surgery and the patient may experience some discomfort in the renewable period.

LASIK surgery (laser in situ keratomelusis) - a tool that is used to create a thin flap edge of the left circle conditions attached, as a hinge. Just think, a portable CD player on its open door hinge. Flap is turned open; laser show in order to change the shape of the cornea is like having PRK. Flap, and then placed in position. Rapid visual recovery and the level of discomfort is minimal.

Creatine kinase (conductive keratoplasty) - Recently, apart from the refractive surgery. It uses radio waves, rather than laser to reshape the cornea shape. Limitations of the procedure is that it can only be said to the patient, is a predictable or presbyopic (those who need reading glasses), and "touch the body," a common six months later - three years. Very unique advantage of this procedure is that, in many circumstances, it can provide a certain degree of distance and near vision in a single eye!
