Publication number: 20230329690Abstract: Provided is an eyelid opening device capable of easily and safely opening eyelids. When installing the eyelid opening device on eyelids, by closing the gripping portion, the opening direction of the first hooking portion and that of the second hooking portion are changed from the upper side or the lower side to the rear while narrowing the distance between the first hooking portion and the second hooking portion by the arm portion of the first arm portion and the second arm portion. Then, the gripping portion is opened to change the opening direction from the rear side to the upper side or the lower side by gradually increasing the distance between the first hooking portion and the second hooking portion via the first arm portion and the second arm portion.Type: ApplicationFiled: October 11, 2021Publication date: October 19, 2023Applicant: MIRAI EYE INC.Inventors: Junsuke AKURA, Motohumi TSUDA

Patent number: 11547553Abstract: An accommodative intraocular lens capable of effectively exerting a focus adjustment function includes an optical portion and a plurality of support portions arranged around the optical portion. The support portion includes an anterior support portion and a posterior support portion, and the anterior support portion presses an anterior capsule and the posterior support portion presses a posterior capsule by the elastic force of the support portion. When the lens capsule is in a distance vision state or in a near vision state, as the pressing force of the anterior capsule against the anterior support portion increases or decreases, the anterior support portion deflects backward or returns forward while maintaining the radial position of the base end portion, so that the tip end portion of the anterior support portion moves backward or forward greatly while maintaining the radial position, and the optical portion moves backward or forward accordingly.Type: GrantFiled: October 2, 2018Date of Patent: January 10, 2023Assignee: MIRAI EYE INC.Inventor: Junsuke Akura

Publication number: 20220362010Abstract: An intraocular lens includes an optical portion and a support portion. The optical portion has an anterior optical plate portion and a posterior optical plate portion arranged on the anterior and posterior sides of the lens capsule. An optical body portion is arranged between the anterior optical plate portion and the posterior optical plate portion. The support portion has an outer support plate portion. An anterior support plate portion extends inwardly from an anterior end portion of the outer support plate portion and connects to a peripheral portion of an anterior optical plate portion of optical portion. A posterior support plate portion extends inwardly from a posterior end portion of the outer support plate portion and connects to a peripheral portion of a posterior optical plate portion of the optical portion. The anterior support plate portion and the posterior support plate portion extend inward and rearward or inward and forward.Type: ApplicationFiled: September 18, 2020Publication date: November 17, 2022Applicant: MIRAI EYE INC.Inventor: Junsuke AKURA

Publication number: 20220151769Abstract: An accommodating intraocular lens includes a lens capsule expansion bag placed in a lens capsule whose anterior capsule has been incised in ophthalmic surgery. An intraocular lens is placed in the lens capsule expansion bag. The lens capsule expansion bag includes an anterior bag portion in contact with an anterior capsule, a posterior bag portion in contact with a posterior capsule, and an intermediate bag portion in contact with an equator. The intraocular lens includes an optical portion and a support portion. The support portion includes an anterior support portion in contact with the anterior bag portion and a posterior support portion in contact with the posterior bag portion. In response to the movement of the lens capsule, the lens capsule expansion bag deforms. The anterior support portion of the intraocular lens greatly deflects or returns accordingly, whereby the optical portion is largely moved in the anterior-posterior direction.Type: ApplicationFiled: April 22, 2020Publication date: May 19, 2022Applicant: MIRAI EYE INC.Inventor: Junsuke AKURA

Patent number: 10028823Abstract: An intraocular lens includes a lens capsule expanding device and an optical portion. The lens capsule expanding device includes a front supporting portion to make contact with an inner surface of an anterior capsule. A rear supporting portion provided on a rear side of the front supporting portion makes contact with an inner surface of a posterior capsule while facing the front supporting portion. A connecting portion connects the front supporting portion and the rear supporting portion so as to have biasing force in a direction of separating the front supporting portion and the rear supporting portion from each other. Due to the biasing force, the front supporting portion presses the inner surface of the anterior capsule and the rear supporting portion presses the inner surface of the posterior capsule. The optical portion changes the curvature of a central portion according to movement of the connecting portion.Type: GrantFiled: December 10, 2014Date of Patent: July 24, 2018Assignee: MIRAI EYE INC.Inventor: Junsuke Akura
