Abstract

TORICINTRAOCULAR LENS AND INTRAOCULAR-LENS INSERTION INSTRUMENT A toric intraocular lens includes a lens body having a flat meridian and a steep meridian, a pair of support portions for positioning the lens body in an eyeball, and connecting portions for connecting the lens body and the support portions. The toric intraocular lens is housed in an intraocular lens insertion apparatus that includes a tubular apparatus body having an insertion tube at a distal end of the apparatus body for inserting the toric intraocular lens into the eyeball and a plunger for moving the toric intraocular lens to a distal end of the insertion tube. 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 of the optical axis and connects the connecting portions with each other, at which a tip of the plunger contact a circumference of the lens body. An acute angle between the flat meridian of the lens body and an axis of the plunger along which the toric intraocular lens is pushed by the plunger is larger than ° and equal to or smaller than 90 ° .
