  • 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.

  • Patent number: 11475797
    Abstract: A simulated eyeball for training in ophthalmic surgery includes a simulated sclera region that constitutes a simulated sclera, and a conductor layer that is formed on a side of the simulated sclera region that is on an interior of the simulated eyeball, the conductor layer forming a simulated choroid region.

  • Publication number: 20220051591
    Abstract: A simulated sclera 2 is obtained by including a plurality of fiber layers (a) and a resin (b) in contact with the fiber layer (a), having a. fiber diameter of a fiber constituting the fiber layer (a) of 0.6 ?m or more and 170.0 ?m or less, laminating the plurality of fiber layers (a), and impregnating the laminated fiber layers (a) with the resin (b).

  • Publication number: 20190362654
    Abstract: The invention provides an inner limiting membrane peeling model that is used in procedure training in peeling of the inner limiting membrane. The model has: a simulated retina and a simulated inner limiting membrane formed on the simulated retina. The simulated inner limiting membrane is formed of a hydrophilic polymer gel that is formed mainly of a water-soluble polymer. At least when used in the above procedure training, the model is disposed with the simulated inner limiting membrane immersed in water or an aqueous solution containing a predetermined solute.
