Embodiment Construction

[0046] The implementation of the present invention will be described in detail below with reference to the drawings and examples.

[0047] see figure 1 As shown, a multifocal artificial cornea according to the present invention includes a stent 10 and a mirror post 20 that is connected with the stent 10, so as to be used for keratoplasty. The view of the object.

[0048] Please refer to Figure 8 , Figure 9 As shown, the bracket 10 is used to carry and install the mirror column 20. The bracket 10 includes a main structure 101 and a clamping structure 102 formed on the outer periphery of the main structure 101. The main structure 101 has a spherical structure, and an opening is provided in the middle of the main structure 101. 11. The opening 11 is pierced with a mirror column 20. Specifically, the inner peripheral wall of the opening 11 is provided with an internal thread for matching installation and connection of the mirror column 20. In this embodiment, the outer circum...

Abstract

The invention discloses a multi-focus artificial cornea which comprises a frame and a lens column connected with the frame in a matched mode. The frame comprises a main body structure; an opening is formed in the middle of the main body structure; the lens column is arranged in the opening in a penetrating mode; the lens column comprises a light guide structure with multiple focuses, so that a plurality of corresponding diopters are formed through the light guide structure during light zooming; and the lens column is made of a PMMA material. The invention further discloses a preparation process of the multi-focus artificial cornea. According to the multi-focus artificial cornea disclosed by the invention, through the multi-focus light guide structure, not only can a patient achieve a short-distance view field, but also a far-distance view field can be achieved; when a user sees far, light energy distributed to a far focus is improved, and a good far vision is generated, when the user sees near, due to reflection and light stimulation, light energy distributed to a near focus is improved, a good near vision is generated, and far-end and near-end view fields are achieved, and the user has a real intermediate vision.

Description

technical field [0001] The invention relates to a medical device, in particular to a multi-focus artificial cornea and a preparation process thereof. Background technique [0002] The artificial cornea is a product similar to the human cornea made of medical polymer materials. The artificial cornea includes two parts: an optical lens column and a bracket. The optical mirror column is made of transparent material with excellent optical properties and stable physical and chemical properties, which is used to replace the cloudy cornea that obstructs the optical pathway of the eyeball after disease; the bracket is equivalent to the bridge connecting the optical mirror column and surrounding tissues, so it is required to have a good Histocompatibility. [0003] When the human cornea is damaged and an artificial cornea is installed, the lens needs to be removed in order to avoid complications. It is suitable for patients with good fundus function but corneal damage who cannot un...
