Title:
INTRAOCULAR LENS INSERTION APPARATUS
Document Type and Number:
Japanese Patent JP2007307082
Kind Code:
A
Abstract:

To provide an intraocular lens insertion apparatus capable of pushing out a lens smoothly into an eye by an extruding shaft as it is from the state of keeping the lens.

The insertion apparatus is the lens insertion apparatus of the intraocular lens for moving the intraocular lens 1 from a lens holding part in the distal end direction of the insertion apparatus by the extruding shaft 6 and inserting it into the eye. The lens holding part has a first holding part 4 and a second holding part 3 which can be abutted to surfaces on the mutually opposite sides in a lens marginal part. When a position in the distal end direction viewing from the center of the lens at the marginal part is defined as a 0° position, the first holding part 4 can be abutted to a region behind the position of a first circumferential direction angle at least larger than 45° and smaller than 70° on both sides in the circumferential direction from the 0° position of the marginal part. The second holding part 3 can be abutted to a region behind the position of a second circumferential direction angle larger than the first circumferential direction angle on both sides in the circumferential direction from the 0° position of the marginal part.
