METHOD FOR FEMTOSECOND LASER CORRECTION OF MYOPIA AND MYOPIC ASTIGMATISM FOLLOWING POST-LASIK COMPLICATIONS Russian patent published in 2015 - IPC A61F9/08 A61N5/67 

FIELD: medicine.

SUBSTANCE: new graft is formed by FemtoLASIK technique at a depth, which is 20 mcm less than that of an incompletely formed graft in the corneal area and 1 mm less in diameter than that of the incompletely formed graft; the grafts have a common centre. The newly formed graft is separated after pre-separation of an edge of this graft starting from a graft pedicle and extending sequentially along the whole circular length; the graft itself is separated by means of a micro spatula curved along a corneal curvature. The spatula is brought along the pedicle full-length and pushed to an opposite side by rocking motions. After separation, the graft is elevated, and a stromal bed is ablated; this involves using ablation algorithm normograms to provide a refraction effect combined with removing the residual incomplete graft in depth.

EFFECT: method enables ensuring the highest possible visual acuity, reducing a rate of operative and postoperative complications.
