Abstract
A toric intraocular lens includes a lens body, support portions, and connecting portions for connecting the lens body and the support portions. The lens is housed in an insertion apparatus that includes a tubular apparatus body having an insertion tube for the lens and a plunger for moving the lens. Each of the connecting portions is arranged at a position where the connecting portions face each other across a center of an optical axis of the lens body. One end of the flat meridian of the lens body is located at a position opposite to a position, with respect to an axis that passes through the center and connects the connecting portions, at which the plunger contacts the lens body. An angle between the flat meridian and an axis along which the lens is pushed by the plunger is larger than 0° and equal to or smaller than 90°.
