KEY TAKEAWAY POINTS
• Wavelight plus is an evolution in creating an ablation profile by representing the pre-operative eye using a virtual 3D eye model constructed using multiple data sources.
• The data to create the 3D eye model are derived from a single diagnostic device that integrates a Scheimpflug tomographic apparatus, a Hartman-Shack wavefront sensor, and partial coherence interferometry biometer.
• In contrast to current technologies, the wavelight plus ablation algorithm additionally simulates and optimizes the post-operative anterior corneal surface within the 3D eye model to achieve the intended correction while considering geometric and optical properties of the individual eye. These include corneal anterior and posterior curvature, total ocular wavefront, the effect of anterior chamber depth to the ray tracing, anticipating anterior surface of the crystalline lens and axial length.
• The new ablation algorithm includes compensation for peripheral laser ablation efficiency, epithelial remodeling, and biomechanical influences that can observed with standard LASIK.
