WebWhen light rays enter the eye and traverse the different refractive indices, the wavefront surface changes, taking on a shape unique to that eye. These variations are called wavefront aberrations. Depending on the instrument, an operator can detect a corneal wavefront, an internal wavefront or a total wavefront (corneal+internal). WebIntraoperative wavefront aberrometry can also aid surgeons in selecting the correct axis for toric IOLs as well as placement of limbal relaxing incisions (LRIs) for astigmatism correction. 1 The first commercially available …
