Problems solved by technology

[0003] 1. During the wearing process of corneal contact lenses, the blinking movement will cause the soft contact lenses to slide back and forth and wear the cornea; although the hard contact lenses can adjust the stability under the blinking movement (blinking and squinting). High, but increases wearer's discomfort;
[0004] 2. In order to ensure the stability of the curved surface of the contact lens, the material strength is high. Generally, a harder material is selected for self-made or commercial hard contact lenses, which sacrifices water content and oxygen permeability, shortens the wearing time, and increases the wearer's Risk of corneal damage lesions;
[0005] 3. The electrochemical sensor circuit coated on the surface destroys the smoothness of the contact lens surface, which greatly reduces the wearer's comfort. health hazard;
[0006] 4. In the biological sensor without circuit, the capture antibody only exists on the surface of the contact lens, and the diagnosis and treatment efficiency is low

Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.

[0031] refer to Figure 1 to Figure 2 , in one embodiment, a microstructured mechanically flexible smart contact lens, comprising a hollow ring-shaped porous grid formed by one or more deformable elastic mechanical units according to one or more distribution rules structure, wherein the annular layout is formed by the periodic combined arrangement of the deformable elastic mechanics units in the circumferential and radial directions or in an orthogonal manner. This kind of microstructure design makes it maintain low main curvature fluctuations under the loads of extrusion, torsion and shearing imposed by the blinking movement of the human eye, weakening or eliminating the obvious continuum annular thin shell near geometric defects. buckling phenomenon...

Abstract

The invention relates to a micro-structure corneal contact lens and a preparation method thereof. The corneal contact lens adopts a mechanical flexible material and comprises a porous grid structure of a hollow annular layout formed by one or more deformable elastic mechanical units according to one or more distribution rules, wherein the annular layout is formed by periodically annularly and radially combining and distributing or orthogonally combining and distributing the deformable elastic mechanical units. The micro-structure corneal contact lens and the preparation method thereof with certain biological tearful eyes detection capacity are low in cost, expandable, capable of being customized and capable of realizing the mass production and wide in application range of people.

Description

technical field [0001] The invention relates to a microstructured corneal contact lens and a preparation method thereof. Background technique [0002] The development of biomedical contact lenses has been more than ten years. Especially in recent years, with the development of micro-nano-scale materials and manufacturing processes, contact lens sensors based on microelectronic systems and contact lenses for diagnosis and treatment based on biochemical detection have gradually entered research. In the field of vision of researchers, the integration of life science, material science, engineering and many other fields has made contact lenses beyond the basic function of vision correction, and their significance as a flexible eye detection platform has become increasingly prominent. However, it has not yet obtained a good solution for its basic defects and the contradiction between the preparation process and the addition of biomedical functions, as follows: [0003] 1. During ...
