Abstract: An intraocular lens (IOL) with an adjustable diopter after surgery is disclosed. According to an aspect of the present disclosure, the intraocular lens with an adjustable diopter after surgery may include: a haptic with a cylindrical receptacle, wherein one or more fixtures are configured to extend outwardly on an outer surface of the receptacle; an optic mounted within the receptacle of the haptic, and configured to refract a light, wherein a thread is formed on an inner circumferential surface of the receptacle, and the optic is configured such that an outer circumferential surface thereof engages with the thread and rotates to be able to move forward or backward in a direction in which the light is incident in the receptacle; and one or more magnetic members provided externally in at least one location at a periphery of the optic to rotate the optic by magnetic force.

Abstract: Disclosed is a cannula fixing device for insertion into a body including a needle having a specific length, and inserted into the body, a connection part connecting a first tube that supplies a solution to the needle, and the needle, and an expansion part that is selectively expanded from an outer peripheral surface of the needle inserted into the body.

Abstract: An embodiment relates to an astigmatism axis adjustable artificial lens which is adjustable so that a correction axis of the artificial lens matches an astigmatism axis when the astigmatism axis and the correction axis of the artificial lens do not match. Here, the astigmatism axis adjustable artificial lens includes a support part and an optical lens part. The support part is fixed to a lens capsule of a patient's eye. The optical lens part is coupled to the support part and has a correction axis that matches the patient's astigmatism axis. The optical lens part is rotatably coupled to the support part to be adjustable so that the correction axis matches the patient's astigmatism axis.

Abstract: An embodiment relates to a safety vitreous body cutting device capable of safely removing only a vitreous body attached to a retina without damaging the retina. Here, the safety vitreous body cutting device includes a tubular body part, a cutter part, and a safety net part. The tubular body part is formed in a cylindrical shape, negative pressure is provided at the inside, and an open hole is formed on the outer circumferential surface of a distal end. The cutter part reciprocates along the axial direction of the tubular body part at the inside of the tubular body part to cut the vitreous body introduced into the open hole. The safety net part is provided at the distal end of the tubular body part, and allows the vitreous body to pass through, but prevents the retina tissue from passing through.

Abstract: Disclosed is an eyelid speculum including a frame, a first rotary arm coupled to one side of the frame to be rotatable, a second rotary arm coupled to an opposite side of the frame to be rotatable, a movement part configured to move the first rotary arm and the second rotary arm such that the first rotary arm and the second rotary arm are moved in a direction, in which they become closer to or more distant from each other, a first support arm coupled to the first rotary arm to be rotatable, and configured to support an upper eyelid, and a second support arm coupled to the second rotary arm, and configured to support a lower eyelid.
