Advanced Custom LASIK and PRK Wavefront vs. Optimized vs. Contoura
Advanced wavefront-guided, advanced wavefront-optimized, and advanced CONTOURA LASIK and PRK are customized versions of LASIK and PRK vision correction surgery. Wavefront-guided, wavefront-optimized, and topography (or CONTOURA) guided LASIK techniques use cutting-edge technology to map and evaluate the unique features of your eye.
“Wavefront” refers to a surface perpendicular to corresponding points on multiple rays of light. During advanced wavefront LASIK, your eye surgeon will use a highly advanced, special instrument called a wavefront aberrometer to take measurements of your eye, using a beam of
light. The wavefront aberrometer uses the measurements to create a 3D wavefront map, which includes any minor flaws in your vision. A wavefront map is as unique as your fingerprint. Your surgery will follow this map and correct your eyes precisely, in a way that is completely
personalized to you.
Although they are different procedures, both wavefront-guided and wavefront-optimized use this mapping system to generate customized results. CONTOURA LASIK and PRK are topography-guided custom laser vision correction procedures to treat myopia with or without astigmatism. These procedures provide the following benefits:
- Increased precision for patients with aberrated corneas
- Highly personalized measurements
- Vision mapping that details vision imperfections
- Laser correction that is personalized to your vision mapping if you do require it
Each advanced custom procedure is designed uniquely to address or prevent specific concerns. So, which is best for you?
Wavefront-guided LASIK is different from the usual LASIK procedure because it has a double approach to correcting your vision. Wavefront-guided LASIK technology corrects major vision errors, as LASIK usually does, and it also addresses minor irregularities in your vision system, called higher-order aberrations.
Wavefront-guided LASIK procedure will take slightly longer than conventional LASIK surgery. However, it is excellent for patients who have more subtle vision concerns, including those that glasses or contacts cannot correct.
It detects aberrations in the entire vision system, including both cornea and the lens. Some patients do not require correction of lens aberrations. Some patients also are not well-suited for this type of correction because of the thickness and shape of their cornea.
Advanced wavefront-optimized LASIK is similar to conventional LASIK, but with some enhancements. In this type of customized correction, your unique corneal curvature parameters are entered into the laser. The reshaping is based on these parameters to customize the LASIK or PRK to your unique corneal shape, resulting in more precision and better quality of vision.
During your procedure, the program directs the laser to treat both the center and the periphery of your cornea, which allows it to maintain its natural shape. This is what prevents any possible light-related distortions.
Advanced wavefront-optimized LASIK has a wide range of treatments, including nearsightedness, farsightedness, and astigmatism and the surgeon can successfully correct higher levels of myopia, astigmatism, and hyperopia than other custom LASIK treatments. Advanced wavefront-optimized LASIK has extremely reliable measurements, even in the case
of eyelid interference, poor eye alignment, and disturbances of ocular surface.
Advanced CONTOURA topography-guided
With this treatment, the surgeon can treat many corneal higher-order aberrations as well as myopia and astigmatism. The treatment does remove more corneal tissue that wavefront-optimized LASIK and PRK. It is, therefore, not suited for patients with thinner corneas.
Which is best for me–advanced wavefront-optimized, advanced wavefront-guided, or
advanced CONTOURA topography-guided?
