PROBLEM TO BE SOLVED: To provide a capsulorhexis cutter that enables intuitive operation and circular capsulorhexis.SOLUTION: A rotary member 2 rotatable around an axis line O is provided with a second through-hole 5b for penetrating through the rotary member 2 along the direction of the axis line O. The second through-hole 5b is hooked by an operation instrument 7 for pressing and rotating the rotary member 2 around the axis line O. Also, a blade part 6 is provided which projects from the rotary member 2 downward in the direction of the axis line O. When the rotary member 2 is rotated by the operation instrument 7 hooked in the second through-hole 5b around the axis line O while the blade edge of the blade part 6 is stuck into a patient's anterior capsule 10, a cut line where the blade edge of the blade part 6 cuts the anterior capsule 10 is derived in an arc shape.SELECTED DRAWING: Figure 6C |
