Publication number: 20220365373Abstract: The object of the invention relates to a method of designing a colour filter for modifying human colour vision by defining the spectral transmission function of the colour filter such as to maximise colour discrimination between more than one element, colour sample, of a colour sample set when a targeted human eye, the colour vision of which is to be modified, is viewing the colour sample set with the colour filter, and at the same time such as to minimise the difference between the colour identification of the colour samples by the targeted eye and a reference eye having a reference colour vision. The object of the invention also relates to such a colour filter, such a colour filter set, and the use of such colour filter and a method for modifying human colour vision.Type: ApplicationFiled: October 2, 2020Publication date: November 17, 2022Inventors: György ÁBRAHÁM, Róbert Tamás FEKETE, László KONTUR, Péter KONCSÁR

Publication number: 20210186683Abstract: An injection system for an intraocular lens (IOL) utilizes a folding device for the IOL. The folding device comprises a pair of co-acting winglets pivotable between an open position and a closed position, and together defining a hinge axis and a receptacle for the IOL. Each winglet has an outwardly extending, unitary leg portion defining a base plane that includes the hinge axis and a motion limiting protuberance on each said leg portion extending from the base plane. The base planes are situated at an angle relative to one another and the protuberances abut one another when the winglets are in the open position. The base planes merge into a single plane when the winglets are in the closed position.Type: ApplicationFiled: February 23, 2021Publication date: June 24, 2021Inventors: Peter HANGYA, Laszlo KONTUR

Publication number: 20130066422Abstract: An intraocular lens for implantation in the ciliary sulcus of the eye has an optical part, on the periphery of which are arranged at least two haptic struts in the form of closed loops arranged symmetrically on each side of the optical part. Each loop is formed by at least three segments interconnected by flexion points, an arched upper segment forming the part for contact with the sulcus of the eye, and two lower segments providing the join between the upper segment and the optical part of the lens, to which they are also connected by flexion points. The length of the upper segment is less than the sum of the lengths of the lower segments and of their spacing (D) in the area of their connection to the optical part. The spacing is such that the lower segments converge on each other in the direction of the optical part.Type: ApplicationFiled: September 11, 2012Publication date: March 14, 2013Applicant: QMP HOLDING GMBHInventors: Rüdiger DWORSCHAK, László KONTUR
