✦ Synopsis
Background and Objective: Reduction of thermal damage inbred with laser surgery is an ongoing challenge. The cavitation effect has been shown to facilitate the transmission of a laser beam through the otherwise opaque water layer. We suggest that by immersing the target tissue in water during laser surgery, thermal damage will be diminished.
Study DesignfMaterials and Metho&:
A method of irradiating tissue by COB laser through a layer of a few millimeters of water is described. A series of experiments was conducted on fresh bovine cornea immersed in water or in air, histology of thermal damage was compared.
Results:
We were able to show that irradiation of tissue immersed in water reduces the thermal damage caused to the area surrounding the incision as compared to the damage caused during irradiation of tissue in air (P < 0.001).
ComZusiorc Laser surgery of tissue immersed in water can reduce the inbred thermal damage. Application of this method to clinical use may result in precise, clean cutting, and enable the use of C o g laser through water.
