Corneal implant to be introduced into the optical centre (Z) of the cornea of the human eye for the purpose of correcting impaired vision, in particular presbyopia, or presbyopia in combination with hypermetropia or myopia. To propose a corneal implant which is suited for introduction into the optical centre (Z) of the human eye, and which may be applied for correcting presbyopia on its own or in combination with hypermetropia or myopia, the effective thickness (d) of the corneal implant (2), measured in the direction of the optical axis (5) of the eye, must be larger than 50 mum and the maximum width (b), measured in a plane perpendicular to the direction of thickness, must be less than 1 mm, the corneal implant (2) having no imaging function in relation to the human eye.
