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
Claims11
A method of producing microstrands of collagen, comprising:
- 61 forming a solution of collagen using a solvent,
- 62 spraying said solution of collagen onto a conductive target from a conductive spraying needle that is maintained at a high potential with respect to said target
- 63 moving said needle to and fro with respect to said target,
- 64 allowing said solvent to evaporate from said target so as to form collagen fibrils or strands on said target upon the evaporation of said solvent, and
- 65 continuing said spraying until a mat of said fibrils or strands are formed on said target.
