Can You Avoid Lasik Problems With Screening And Tests?
The complexity of the procedure is often obscured by the office-like milieu of the surgery room, the fact that it takes only a scant few 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 computer-controlled 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 eye surgery has its inherent limits as to how much vision correction it can accomplish. Patients with gravely poor eyesight are 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 eye surgery. Since, the visual acuity constantly changes
until the age of 18, eye surgeons prefer to operate patients who are
well over 18 and whose prescription has completely stabilized. A simple
refractive examination followed by a meticulous comparison with the
patient’s early medical records would reveal whether the prescription
has stabilized or not.
The eye surgeon should also carry out
comprehensive tests of the eye anterior (front) and posterior (back).
This is helpful in determining certain eye ailments that might rule
out as a treatment option. For instance, a posterior examination might
identify eye diseases, such as ocular hypertension, glaucoma and diabetic retinopathy.
All in all, prior screening and tests are valuable and rather indispensable in
the sense that they determine the possible candidature of a patient for LASIK
surgery.
Finding a that you are confident of working with will ease your concerns about
problems with LASIK eye surgery.
