Title: OPTICAL CYLINDER AND METHOD OF SURFACE TREATMENT OF THE SAME
Abstract:
Disclosed is an optical cylinder of a corneal prosthesis comprising: a) an optical cylinder comprising a solid polymer (preferably, PMMA), and b) a plurality of nanoparticles (preferably, hydroxyapatite, HAp) forming a substantially uniform layer on a circumference of the solid polymer surface of the optical cylinder. Also disclosed are methods of surface treatment of optical cylinders of corneal prostheses, and corneal prostheses thereof, comprising contacting an optical cylinder with a mixture comprising an organic solvent, a dispersant (i.e. PMMA), and a plurality of nanoparticles via dip- coating.
