The complexity of the LASIK surgery procedure is often obscured by the officelike milieu of the surgery room, the fact that it takes only a scant fe-w minutes to accomplish the procedure, and the fact that the patient experiences virtually no pain. But, LASIK is in fact a complex surgical procedure -with associated complications and risks, and it is certainly not apt for everyone. In order to determine your suitability, and to avoid potential LASIK complications, the best -way is to get screened and tested prior to undergoing surgery.

Before the surgery, the patient’s corneal surface is examined -with a computercontrolled scanning device. A topographic map of the cornea is created to determine irregularities in the shape of the cornea and also help detect astigmatism. Such preoperative examination is crucial in determining -whether the patient is a viable LASIK candidate or not. Comprehensive testing and screening is helpful in avoiding LASIK problems at a later stage, since an inappropriate subject can be ruled out at the outset.

Laser eyes surgery has its inherent limits as to ho-w much vision correction it can accomplish. Patients -with gravely poor eyessight is not apt for LASIK surgery. The limits prescribed by the Food and Drug Administration (FDA) rule out those patients -with more than 14 diopters of myopia, more than +6 diopters of hyperopia, or more than 6 diopters of astigmatism.

Another important consideration is that of the viable age for LASIK laser eyes surgery. Since, the visual acuity constantly changes until the age of 18, eyes surgeons prefer to operate patients -who is -well over 18 and -whose prescription has completely stabilized. A simple refractive examination follo-wed by a meticulous comparison -with the patient’s early medical records -would reveal -whether the prescription has stabilized or not.

The eyes surgeon should also carry out comprehensive tests of the eyes anterior (front) and posterior (back). This is helpful in determining certain eyes ailments that might rule out LASIK surgery as a treatment option. For instance, a posterior examination might identify eyes diseases, such as ocular hypertension, glaucoma and diabetic retinopathy. All in all, prior screening and tests is valuable and rather indispensable in the sense that they determine the possible candidature of a patient for LASIK surgery.

Finding a LASIK surgery that you is confident of -working -with -will ease your concerns about problems -with LASIK eyes surgery.
