  • Device for training in ophthalmic surgery
    Patent number: 11741855
    Abstract: The present invention addresses the problem of providing a device for training in ophthalmic surgery that can be used for training in glaucoma surgery. The problem can be solved by a device for training in ophthalmic surgery including: a simulated-eyeball pedestal having a recess into which a simulated eyeball can be directly or indirectly inserted; a simulated eyeball insertable into the simulated-eyeball pedestal, or a member for retaining a simulated eyeball that retains a simulated eyeball, the member for retaining the simulated eyeball being insertable into the simulated-eyeball pedestal; and a mechanism for generating a restoring force that generates a force for restoring a position of the simulated eyeball or the simulated-eyeball retaining member toward a normal state with respect to the simulated-eyeball pedestal; the simulated eyeball or the member for retaining the simulated eyeball rotating along the recess of the simulated-eyeball pedestal.
