Method for implanting intrastromal corneal segments when type I corneal ectasia

摘要

implantation method intrastromal corneal segments with I type corneal ectasia, comprising measuring the spherical refraction equivalent (SE), the implantation of a segment, the selection of the thickness 150, 200, 250, 300, and 350 microns, depending on the value of FE, the choice of the arc length of the segment of 160 ° or 210 °, characterized in that the additional area is determined ectasia segment implanted so that it overlaps the maximum zone ectasia, and the input section for forming tunnels carried by strong corneal meridian, wherein when the thickness of the FE 1-2,45 D segment coagulant is 150 microns in SE 2,5-3,45 D - 200 microns, SE 3,5-4,95 D - 250 microns, SE 5,0-6,45 D - 300 microns, SE 6,5 D and a - 350 microns and a length of the arc segment is selected depending on the area ectasia (S), namely, when S is not more than 12.75 mmdlina arc is 160 °, if S 12.75 mm- more than 210 °.
