Abstract
Methods for the amelioration of ectatic corneal disorders using corneal augmentations are disclosed. The shape of the augmentation is determined using data obtained from mapping of a patient's cornea based on computerized corneal topography and tomography. Factors considered include the maximum keratometry and specific iso-deviation contours. In one embodiment, an augmentation is inlayed into a femtosecond created, intrastromal pocket. In a further embodiment, an onlay augmentation is positioned over a region of the cornea from which the epithelial layer has been removed. The onlay is held in place by glue, sutures, tucking under a perimeter chamfer, or some combination thereof, until the epithelial layer regrows over the augmentation. In a further embodiment, the inlay or only augmentation is followed by a post-augmentation, further reshaping of the corneal augmentation. In one embodiment, this further reshaping is photorefractive keratectomy (PRK) surgery. In another and a phototherapeutic keratectomy (PTK) surgery.
