AI Technical Summary
Technical Problem
Conventional intraocular lens injectors face issues with complex lens setting and potential damage due to user handling, and semi-preset type injectors struggle with maintaining the lens in the correct position, leading to inaccurate ejection.
Method used
An intraocular lens holder with a restricting member that secures the lens in place during storage and releases the restriction when attached to the injector, featuring a mounting member, pressing member, and lid member to ensure precise positioning and ejection.
Benefits of technology
Enables accurate setting and ejection of the intraocular lens by restricting movement during storage and releasing the restriction for seamless extrusion, enhancing operational precision and reducing lens damage.

Abstract
The purpose of the present invention is to enable accurate setting of an intraocular lens into an injector, and to enable accurate discharge of the intraocular lens by means of the injector. An intraocular lens holder (10) comprises a restriction member (2) that restricts movement of an intraocular lens (7) in a storage state in which the intraocular lens (7) is stored, and releases the restriction on the movement of the intraocular lens (7) through attachment to a distal-end chip (30).
