23 Jul Corneal graft cascade method for improving tissue engineering artificial cornea diopter
Abstract
The invention discloses a corneal graft cascade method for improving the tissue engineering artificial cornea diopter. A tissue engineering artificial corneal graft is manufactured by polymeric biomaterials through 3D (three-dimensional) printing; the corneal graft comprises a front end corneal graft and a back end corneal graft; the front end corneal graft has the similar dimension and curvature to those of the patient cornea, and is put on a corneal recipient bed; the back end corneal graft has the similar dimension and curvature to those of a crystalline lens of a patient, and is put between the iris and the crystalline lens of the patient; by combining the diopter of the front end corneal graft, the front wall and back wall curvature in the back end corneal graft is regulated; the integral diopter is improved to the normal value; the corneal graft cascade is realized; the technical problem of insufficient single tissue engineering artificial cornea diopter is solved.
