Combining Multimodal Wavefront Examination and Digital Refraction to Create a Rapid and Accurate Approach (XFraction) for a Total Visual System Assessment for Intraocular Lens Selection

Abstract

Following advances in intraocular lens technology in recent years, greatly increased options are now available to the ophthalmic surgeon. However, there is a need for improved diagnostic technologies to optimize outcomes and select the best treatment strategies. A process combining multimodal wavefront examination and digital refraction, wavefront optimized refraction or ‘XFractionSM,’ has been recently developed to address this requirement. This novel fusion of techniques increases the amount of data that can be captured from each eye by orders of magnitude and is completed in much less time than former separate methods or manual refraction alone. The result is a process that enhances current procedures, provides superior patient diagnosis over previous techniques through the full optical pathway, and provides multiple benefits to both the patient and physician. The process enables the collection of a large amount of relevant information that makes available new levels of understanding about each patient’s unique visual system. Its use in clinical practice has been further associated with increased practice efficiency, enhanced optimized refractions, improved diagnostic surgical outcomes, and higher levels of patient satisfaction.
