Wavefront LASIK is also known as custom LASIK surgery or wavefront-guided LASIK. This procedure uses three-dimensional measurements to illustrate the way patient’s eye processes images. These three-dimensional models are later used in reshaping the frontal part of the eye – cornea. Cornea is the transparent part of the eye that covers the iris, pupil, and the anterior chamber. Cornea refracts the light, and holds about two-thirds of eye’s total optical power. LASIK is a surgical procedure that is aimed to correcting vision problems and providing patients with alternatives to wearing corrective eyeglasses or contact lenses.
What benefits offers wavefront-guided LASIK
Wavefront-guided LASIK promises the significant improvement in how much and how well a patient is going to see after the surgery. The post-operative risk with wavefront LASIK is reduced to the slightest chance, and may involve glares, halos, and occasional difficulties with night vision.How much and how well a patient sees, depends on vision defects known as lower-order aberrations and higher-order aberrations, respectfully. Low-order aberrations result in refractive errors while higher-order aberrations create problems in contrast sensitivity, glare, shadows and halos.
The greatest benefit of wavefront LASIK, when compared to the traditional procedure, is that it treats both problems. If the surgery is successful, patients will get better chance of achieving better than 20/20 vision, reduced chance of losing best-corrected vision, visual quality or contrast sensitivity, as well as reduced chance of night-vision disturbances and glare.
Who is a good candidate?
Wavefront LASIK relies on standard LASIK candidacy criteria. An ideal LASIK candidate should be at least 21 years old. The proper candidate’s vision has stabilized with using glasses or contact lens prescription for at least 2 years. The patient’s cornea also has to be thick enough and to have appropriate curvature. This is important since the cornea needs to be reshaped. An ideal candidate should also be free of any disease, since this may reduce the effectiveness of surgery and post-surgical recovery.
Is Wavefront LASKIK safe?
Wavefront LASIK is probably the safest procedure in eye surgery. This procedure involves sophisticated three-dimensional eye mapping that helps in the course of surgery. This way, the chances that everything will work as planned are maximized. Otherwise, wavefront LASIK uses the same surgical procedures as traditional LASIK, and more than seven million of them have already been performed successfully.
How much does it cost?
Wavefront LASIK surgery is a bit more expensive than the standard LASIK procedure. This is because it requires the latest technology and consumes more time.
