NIR laser tissue welding of in vitro porcine cornea and sclera tissue.

Background And Objective: The objective of this study was to test the hypothesis that an near infrared (NIR) laser system (1,455 nm) in combination with a motorized translational stage to control the position and speed of the laser beam and a shutter to control the laser exposure to the tissue being welded could be used to successfully weld ocular tissues.

Study Design/materials And Methods: Seventy-five porcine corneas and 23 porcine scleral tissues were welded in vitro in this study. The welded tissues were examined using histopathology and tensile strength analysis.

Aorta and skin tissues welded by near-infrared Cr4+:YAG laser.

Objective: The aim of our study was to explore the wavelength dependence of welding efficacy. Ex vivo samples of human and porcine aorta and skin tissues were investigated using a tunable Cr(4+):yttrium aluminum garnet (YAG) laser.

Background Data: Tissue welding is possible using laser light in the NIR spectral range.
