Toric intraocular lens and intraocular lens insertion device

摘要

Provided is a toric intraocular lens that can further stabilize the extrusion of the toric intraocular lens by the intraocular lens insertion device. The toric intraocular lens has a lens body having a weak main meridian and a strong main meridian, a pair of support parts for positioning the lens body in the eye, and a joint part for joining the lens body and the support part. A toric intraocular lens, the toric intraocular lens is moved to the distal end of the insertion cylinder part with a substantially cylindrical instrument body having an insertion cylinder part at the tip for inserting the toric intraocular lens into the eye. Each joint is provided at a position facing each other across the center of the optical axis of the lens body, and one end of the weak main meridian of the lens body is located on the outer periphery of the lens body. The weak main meridian of the lens body and plunger Acute angle with the extrusion axis of the toric intraocular lens is a configuration is less than 0 ° larger than 90 °.
