Wavefront Guided Lasik Proves to be Effective Eye Surgery

When we experience distortions in our vision, or the way the light enters the eye, these are known as aberrations. Most of these create common problems such as nearsightedness, but less common aberrations, or higher order aberrations, are unable to be treated with traditional methods and can cause a number of other problems in vision.

Higher order aberrations only occur in a small amount of the population, but are unique according to each patient. No two aberrations are exactly the same, and this is why wavefront guided technology is becoming a very popular treatment – it produces a completely individual mapping of the eye, which can more effectively guide the reshaping of the cornea.

Before treatment, aberrations are mapped using an Aberrometer, which then guides the laser across the cornea. Aberrometers work by sending light into the eye, and any errors in its reflection back to the device are captured. All higher and lower aberrations are then displayed as 3D images.

During treatment this data is interfaced with the LASIK system. In this way, each movement of the laser is precise according to your individual aberrations. The system scans the eye so quickly that it also accounts for any tiny movements in the eye to produce accurate results for the best vision possible.

Wavefront guided LASIK is the only way to correct higher order aberrations. Spherical aberration is one of the most common problems that wavefront is excellent at treating. This system produces excellent results due to its individual mapping, and patients will be informed  by their vision specialist as to whether this is the right option for them.

Wavefront data is used to create a very precise treatment for each eye.  Because of the precision attained from the mapping of many different data points in the eye, this procedure can be very effective at curing many higher order aberrations.  The higher resolution the laser mapping can create (which basically means, the more data points used), the better and more accurate the procedure.
