Laser Surgery for Astigmatism: Transforming Your Vision with Topographic Guided Technology -

Second Phase                                                        

Whether the first phase of your treatment involves IntraLASIK or PRK, at his Calgary Centre, Dr. Demong will transform your vision in the second phase using Wavefront Optimization, the foundation of all treatments with the Wavelight Allegretto Eye Q laser. He will customize your treatment even further using the Wavefront Guided mode or Topography Guided mode. The Wavefront Guided mode uses a Wavefront generated template to guide the treatment beam while the Topography Guided mode uses the treatment defined by the Oculyzer topography system. Dr. Demong selects the treatment most suitable for your unique needs but every treatment starts with Wavefront Optimization for the safest, most accurate results possible.

Topography Guided Laser Treatment

In Topography Guided mode, the Allegretto delivers the desired treatment according to customized settings from the corneal topography performed at the time of your assessment.  It is particularly effective for correction of problems directly in the center of vision and addresses defocus errors , especially astigmatism, across a wide range but cannot treat higher order aberrations.

Using Oculink technology, your topographical map is linked to the Allegretto laser system to guide Dr. Demong's treatment of

specialized conditions such as  high astigmatism following corneal transplant surgery or decentered / irregular ablations after previous refractive surgery.  As a corneal specialist, Dr. Demong appreciates the safety, accuracy and control this technique offers, providing a superior alternative over traditional surgical intervention.

The effectiveness of Wavefront Optimization, the safety of Perfect Pulse and the speed of the Allegretto are an integral part of every Topography Guided treatment.
