Zyoptix-WaveFront

In addition to standard visual errors, Zyoptix also measures and treats small vision errors (higher order aberrations) that scatter light in a pattern that is unique to you. These are evident in dim light where a point of light is seen as scattered. These could cause shading to be seen around one edge of a perfectly round light, and they are certainly an important cause of poor quality night vision. About 70% of people with these vision problems could benefit from Zyoptix treatment.

Zyoptix is the name for customized treatments available on the Bausch and Lomb platform. The Zywave aberrometer measures the eye's unique wavefront map and in addition to the refractive error (shortsight, farsight and astigmatism), picks up fine aberrations which are unique to the individual eye. Fine aberrations can account for poor vision especially at night when the pupil is larger and effect of aberrations more pronounced.

The process of wavefront acquisition is more involved and takes a little longer.The software breaks the wavefront into a variety of components for analysis by the surgeon and indicates which specific aberrations are of visual significance. The surgeon at Centre for Sight decides based on the patient's symptoms (night vision problems , glare, halos etc.), pupil size and magnitude of aberrations whether the added expense of performing a Wavefront lasik treatment is worthwhile.

Zyoptix Wavefront Lasik treatments are also useful for treating unusual prescriptions including high levels of astigmatism. The advantage of the Zyoptix wavefront treatment in these cases I is that treatment is limited just to the area that needs to be corrected and is more precise. This combined with iris registration ensures accurate treatment delivery Each wavefront map is unique to each eye and it is vital that the Wavefront lasik treatment is applied in the correct location on the corneal surface.
