METHOD FOR TRANSPLANTATION OF CORNEAL-PROSTHETIC COMPLEX Russian patent published in 2024 - IPC A61F9/07 A61F2/16 

FIELD: medicine; ophthalmology.

SUBSTANCE: corneal-prosthetic complex (CPC) is transplanted, the CPC is prepared, the recipient’s cornea is trepanned, the remaining bridges are dissected, the CPC is placed in the recipient’s bed and the CPC is fixed with interrupted sutures. Trepanation is followed by dissecting the bridges in a counterclockwise direction from 6 o’clock to 12 o’clock, preserving the remaining semicircular bridge between the trepanned cornea of the recipient and the cornea remaining after trepanation (CRAT). Further, the interrupted suture is fixed at 9 o’clock of the CPC to the CRAT, after which the bridges are continued to be dissected, while the jumper is left at 3 o’clock, then interrupted sutures are applied at 8 and 10 o'clock between CPC and CRAT. Remaining bridge at 3 o'clock is dissected, completely removing trepanned cornea of recipient (TCR). Further, the CPC is elevated by creating an angle between the iris and CPC of 45 degrees, and extracapsular EC or IOL removal is performed, thereafter, the CPC is lowered into the recipient’s bed and the operation is completed with the interrupted sutures of the CPC to the CRAT. In a particular case, in the presence of intraoperative complications, the CPC is lowered, fixed to the CRAT with an interrupted suture and the eye condition is normalized, thereafter, the interrupted suture is dissected, and the CPC is raised again, restoring angle of 45 degrees, and the extracapsular EC or IOL removal is completed, after which the CPC is lowered into the recipient's bed and completely fixed with the interrupted CPC sutures to the CRAT.

EFFECT: method enables reducing the risk of intraoperative complications by maintaining a relatively tight anterior chamber and the ability to control the degree of sealing of the eye when performing the CPC transplantation in the patients with burn and dystrophic leukoma in combination with complicated cataract or in the presence of an IOL.
