The required technology for customized corneal ablation

The introduction of wavefront sensing technology and customized corneal ablation has revolutionized the field of refractive surgery. Yet, in order for customized laser vision correction to reach its full potential, a number of technological requirements must be addressed by the specific laser vision correction platform offering this customized procedure. At present,several different technology platforms exist. A more thorough understanding of these platforms will help in evaluating which system is best at eliminating aberrations. The following technology is required to provide what is considered optimal within the current state of knowledge in this field: (1) scanning spot laser delivery, (2) robust eye tracking,(3) an accurate wavefront device, and (4) the wavefront-laser interface.
