  • Use the method of physical exposure (diathermocoagulation, cryocoagulation , cryoblowing , laser therapy).
  • Suckable clouded neny corneal installation solution used ethylmorphine hydrochloride (dionin) rising in a concentration of from 1% to 8% by 1-2 drops 3 times a day;
  • Forced installations and electrophoresis with enzymes: lidase , trypsin, lycozyme (papain).
  • With deep keratitis treatment painkillers added as novocaine blockade nonspecific and spe graphical instruments antiinflammatories general dei Corollary [ phenylbutazone , indrmetatsin , hexamethylenetetramine (urotropin) with glucose intravenously]; corticosteroids in the form of installations, subconjunctival and retrobulbar injections of dexazone , cortisone, hydrocortisone, dexamethasone strictly after the end of corneal epithelization under the cover of antiviral drugs; desensitizing agents (diphenhydramine, tavegil, suprastin , diazolin ); Surgical treatments (Kera toplastika).
