Patent ID: 8795262

Claim:
A method of suturing, repairing and sealing ocular structures, which comprises using a flap of optically transparent, biocompatible biological tissue for application over a surface discontinuity or perforation in the ocular structure, positioning, over the discontinuity or perforation, the flap with a biocompatible chromophore, so that a side of the flap treated with the chromophore is facing and in contact with a surface of the ocular structure, the biocompatible chromophore being located limitedly to said side of a flap, and subsequently fixing the flap to the surface of the ocular structure by photothermal laser-induced welding, wherein the photothermal laser-induced welding is obtained by irradiation of a laser beam emitted from an end of an optic fiber connected to a laser generator, the end being brought into contact with the flap and exerting pressure thereon in order to seal the discontinuity or perforation, the biocompatible chromophore having an optical absorbance band including an emission wavelength of the laser beam.
