ABSTRACT:
A method and means of providing stromal repair and improved refractive correction by creating corneal stromal collagen tissue with fibril diameter and spacing that duplicates the optical transmission and diffusion characteristics of natural corneal collagen. The repair method includes implanting the collagen scaffold during laser corneal ablation or other interlamellar surgery to improve visual acuity or to preclude the possibility of ectasia.
