METHOD FOR SEPARATING GRAFT OF DESCEMET MEMBRANE AND ENDOTHELIUM Russian patent published in 2019 - IPC A61F9/07 A61F9/13 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to ophthalmology. To obtain the Graft of Descemet's membrane (DM) and the endothelium, an external margin of the DM of the corneoscleral donor flap is incised without trabecular meshwork, along the Schwalbe front boundary ring along an arc of a circumference of 320 degrees. Then, the DM is separated from the underlying posterior stroma in the form of a ring segment with an arc length of 320 degrees, with an internal diameter of 8 mm. Next, with the help of tweezers, the seizure of the separated part of the DM for edge thereof is made, the remaining part of the DM is separated to the center of the cornea. Next, trepanation of the corneoscleral flap with separated DM is carried out to obtain the finished DM roll.

EFFECT: method reduces the culling of donor tissue during the preparation of the DM and endothelium graft and the trauma of the endothelium during the separation of the DM from the underlying stroma of the donor, which reduces postoperative complications.
