Abstract

The invention relates to chromophore formulations in semi-solid or solid form to be used for the colouring of biological tissues in order to absorb in a selective and localised manner the laser radiation in the processes of laser welding of biological tissues. These procedures are applied in surgical treatments for the suturing, healing and sealing of incisions and wounds in various types of tissue, such as the cornea, skin and mucous membranes.
