A kind of microstructured corneal contact lens and preparation method thereof

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 ...

AI Technical Summary

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
