Bio Ink Formulations, Bio Printed Corneal Lenticule, And Applications Thereof

Abstract: The present disclosure discloses a xeno-free bio-ink formulation amenable to be printed using a 3D printer. The bio-ink formulation exhibits optimum viscosity in the range of 1690-5300 cP. The present disclosure discloses a bio-printed corneal lenticule obtained from the bio-ink formulation. The bio-printed corneal lenticule as disclosed is of the optimum thickness in the range of 10-500 microns and exhibits transmittance in the range of 80-99%. The present disclosure also discloses a process for preparing the bio-ink formulation as well as for preparing the bio-printed corneal lenticule. Further, the present disclosure discloses a method of treating a corneal defect using the bio-printed corneal lenticule as an implant to treat the corneal defect. The bio-printed corneal lenticule can further be used as a model for in-vitro drug testing and diseases modelling.
