In addition to standard visual errors, Zyoptix also measures and treats small vision errors (higher order aberrations) that scatters light in a pattern that is unique to you. Scattered light errors could, for example, cause shading seen round one edge of a perfectly round light, and certainly they are an important cause of poor quality night vision. About 70% of people could benefit from Zyoptix treatment.
These small errors are detected with wavefront technology and treated by the laser with a combination of smaller and larger beams, allowing the surgeon to deliver a more precise, personalised treatment. |
