METHOD FOR MAKING REFRACTION-CORRECTING EXIMER LASER INTRASTROMAL KERATECTOMY Russian patent published in 2000 - IPC

FIELD: medicine. SUBSTANCE: method involves making installation anesthesia and healing conjunctival cavity. Vacuum ring is installed slice is carried out with flap on pedicle formed. The flap is bent up and laser keratoablation, drug instillation, flap repositioning are carried out. Anesthesia is applied with vasoconstrictor used. Vacuum ring is placed so that its longitudinal axis passes through pupil center. The ring is shifted vertically downward by 0.5-1.0 mm. 0.4-0.6% methyl cellulose solution and 0.17-0.19% sodium hyaluronate solution mixture is instilled into the conjunctival cavity before forming the flap. The flap base is placed in 12 o'clock position so that the lower edge of the flap is not greater than 2 mm apart from limb boundary. The flap is folded with its internal surface inside. The stromal bed is washed with means improving regeneration after performing laser keratoablation. Antibiotic solution and non- steroid preparations are instilled. The flap is manually smoothed in transpalpebral way. EFFECT: enhanced effectiveness of treatment.
