METHOD FOR PREPARING CORNEA TRANSPLANTATION IN VASCULARIZED CORNEA LEUKOMA

摘要

FIELD: medicine.;SUBSTANCE: method involves intravenously introducing chlorine row photosensitizer as liposomes at bolus dose of 1.0-1.5 mg/kg 2 weeks prior to transplantation. The whole cornea surface is exposed to laser radiation field-by-field with the neighboring fields overlapping over 5% of area in 10-15 min after photosensitizer introduction is over. The wavelength corresponds to photosensitizer liposome light radiation absorption maximum. Power density is equal to 100-120 J/cm². Irradiation is carried out within circle in moving from periphery to the center.;EFFECT: emptied and regressed newly formed cornea blood vessels with no bleeding occurred in transplanting cornea.
