Abstract:
An effective method for welding corneal and/or scleral tissues. To join the tissues, laser light is applied using a wavelength which enables penetration of the light to a tissue depth of about 0. 2-2. 0 mm. The wavelength is selected from within one of the following ranges: (1) 1400-1900 nm, or (2) 2100-2400 nm. In epikeratophakia procedures, the wavelength ranges will be 1900-2100 nm or 2400-2650 nm, allowing a tissue penetration depth of about 0. 05-0. 2 mm. A laser power output value is selected so that the tissue temperature during welding remains at about 44. degree. -60. degree. C. This value is between about 30 mW-1. 5 W. The laser light may be applied in the form of a spot-type beam, an elongate beam, or an annular beam. Application of laser light in the foregoing manner enables ocular tissues to be safely and effectively welded, and is useful in corneal transplantation.
A chemically driven HF overtone laser operates from either thermal or electrical dissociation of a molecular gas containing fluorine. Significant output powers are produced from. DELTA. v=2 vibrational transitions. Free F atoms produced by both thermal and electrical dissociation techniques are reacted with a molecular gas containing hydrogen to produce excited HF molecules. Overtone transitions, i. e. ,. DELTA. v=2 transitions are preferentially depleted by both optical enhancement and preinjection techniques to produce overtone laser transitions.
