However, damage thresholds were determined for the spot size of only 0.37\u2009mm due to the low output of the employed SC source at that time. The objectives of this study are to determine the lowest possible corneal damage threshold at a large corneal spot size using a more powerful SC source and provide data for the future possible refinements of laser safety standards.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>A series of experiments was conducted in the New Zealand white rabbit model to determine the corneal damage threshold induced by a 900\u20132000\u2009nm SC source, with corneal 1\/e beam diameter of about 1.2\u2009mm. Slit\u2010lamp biomicroscope was employed to reveal the corneal damage characteristics. By employing the action spectra determined through the analysis of current laser safety guidelines and standards, the effective damage threshold could be calculated.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The determined damage threshold given in terms of the peak radiant exposure for the exposure duration of 0.14\u2009s was 44.3\u2009J\/cm<jats:sup>2<\/jats:sup>. At threshold level, corneal damages involved the epithelium and the shallower stroma.
