METHOD FOR LAYER-BY-LAYER KERATOPLASTY Russian patent published in 2005 - IPC

FIELD: medicine, ophthalmosurgery.

SUBSTANCE: the present innovation deals with technical performance of layer-by-layer keratoplasty in case of considerable corneal thickening. The method should be fulfilled due to dissecting pathologically altered corneal part followed by its removal and substitution with a layer-by-layer corneal transplant. After removing the part of pathologically thickened cornea one should split it along the edge of trepanation channel for the depth of 1-3 mm at developing circular pouch to place there a layer-by-layer corneal transplant. The latter has got the thickness in the center being 0.4-0.5 mm, its edge is thickened up to 0.2-0.3 mm along the whole perimeter for the width 1-3 mm. The transplant should be fixed to recipient's cornea with interrupted sutures.

EFFECT: higher efficiency.
