[Experimental and morphological as well as physical and chemical interaction of laser radiation of a close infrared range with the fibrous eye membrane].
Experimental-and-morphological as well as physical-and-chemical changes occurring in the eye fibrous coat tissues, i.e. the cornea and sclera, at non-ablation impact of fiber laser radiation (Er-glass) with a wavelength of 1.56 mcm were analyzed. Necrobiotic or necrotic changes occur in the tissues with regard for laser radiation capacity and impact duration; subsequently, the regenerative process involving a retraction of the sclera and a flattening of the cornea takes place in the end. When the cornea is heated by fiber laser radiation with a minimally possible intensity (up to 0.3 Wt), a temporary weakening is observed in the corneal rigidity. Should it be accompanied by a simultaneous occurrence of retraction forces coming from the sclera (at its coagulation), it can be used to change, in the clinical controllable mode, the corneal curvature radius.
