Abstract: The invention is a surgical instrument (1) used in ophthalmology, which allows a penetrating or lamellar cornea transplant without the use of suture. It comprises a set of arc segments interconnected by a small diameter polypropylene wire (2), which goes through the internal body structure of each segment. The first arc segment (3), also called the segment guide, is an arc of 160-330 degrees with a circular cross-section and a rounded edge. The second arc segment (4), also called the main segment, is an arc of 270-360 degrees, and has a horizontal or oblique cross-section tangential to the surface of the cornea, or a circular cross-section. The third arc segment (5), also called the secondary segment, has a thickness or cross-section greater than that of the main segment.

Abstract: The object of this patent belongs to the field of opthalmology and is a surgical instrument (1), whose using allows the execution of punctuate of cornea transplant without the use of suture; consists to a set of arms segments interconnected through a wire, “prolene” (2) of small diameter, which goes through internally structured along the body of each segment, with the first segment of an arc, called the guide (3), is conformed by a bow of 300 degrees with a diameter circular section to be defined and rounded edge, the second segment of an arc, called the main arc (4), is the first proof of the number of rings cooptation, preferably built into a material called PMMA, whose arc can vary from 300 to 400 degrees, with thick set and horizontal sections and oblique tangential to the surface of the cornea and the third segment of an arc, called secondary arc (5), which has a greater thickness of the primary segment (4).
