FIELD: medicine.
SUBSTANCE: invention relates to medicine, namely to ophthalmosurgery, and in particular to scleroplasty. Transplant for scleroplasty has polymeric base, covered with porous layer of the same polymer. As polymer base, transplant includes layer, made from porous stretched polytetrafluoroethylene, which has nodular-fibrillar structure. As porous layer, it includes layer of porous polytetrafluoroethylene, which has volume fraction of void space 15-40%, specific surface of void space 0.25-0.55 mcm2/mcm3, average distance between voids in volume 25-30 mcm and average chord volume 8-25 mcm, with the total width of transplant constituting 0.15-0.35 mm (first version). Transplant for scleroplasty can also include porous layer of polymer, whose surface is processed to add compatibility with sclera tissue. Transplant surface is processed by application of allogenic dermal fibroblasts of 3-5 passages of culturing, with the total width of transplant being 0.15-0.35 mm (second version).
EFFECT: chemically and biologically inert transplant, which ensures effect of invasion of sclera tissues, is obtained.
