In three patients with numerous relapses of corneal erosions cryotherapy in the sense of cryostimulation was performed. Short-term medium intense cryoapplication was used - 1 cryocycle of -80 degrees C for 7 seconds on the whole area of the defect, using an applicator with a working area of 2 mm. On the third day after the procedure in all eyes satisfactory epithelization occurred. On the fifth day after the procedure the eye had recovered. The observation period is 13-17 months - no relapse. Cryotherapy proved the most effective of all hitherto used therapeutic procedures.
