Abstract: It is provided an intraocular lens insertion system that achieves a preferable insertion of an intraocular lens without using viscoelastic material in an eyeball. The intraocular lens insertion system includes an intraocular lens insertion apparatus configured to use a predetermined driving force to move an intraocular lens and insert the intraocular lens into an eyeball, an irrigating solution infusion apparatus configured to infuse irrigating solution into the eyeball, a driving source configured to deliver the predetermined driving force to the intraocular lens insertion apparatus, an irrigating solution source configured to deliver the irrigating solution to the irrigating solution infusion apparatus, and a switching unit configured to switch in a multistage manner a control of a delivery of the irrigating solution from the irrigating solution source to the irrigating solution infusion apparatus and a control of a delivery of the predetermined driving force from the driving source to the intraocular lens insertion apparatus.

Abstract: An intraocular lens insertion apparatus includes a substantially tubular insertion member configured to be inserted into an eye, an opening part provided at a tip end of the insertion member to eject an intraocular lens into the eye, and an intraocular lens push member which pushes the intraocular lens to move the intraocular lens through the insertion member and ejects the intraocular lens from the opening part into the eye. An opening direction of the opening part is tilted with respect to a direction in which the insertion member extends, and a recess having a predetermined depth and extending in the extending direction is provided at an outer peripheral surface of the insertion member on an insertion member rear end side of the opening part.
