Problems solved by technology

[0003] Existing soft contact lenses have high hydrophilicity. Because the contact lenses are worn into the eyes, they cover the front of the cornea, hindering the contact between the cornea and air and causing corneal hypoxia. In addition, tears can moisten the cornea , outside the conjunctiva, the lens must also be moistened, resulting in a lack of tears, causing dryness and soreness in the eyes of the lens wearer

Abstract

The invention provides a corneal contact lens nursing composition containing mycose, and also relates to the compositions of the type. The composition comprises the following components in weight percent: 0.001-8% of mycose, 0.01-3% of isotonic regulator, 0.001-4% of buffering agent, 0.01-3% of lubricating moisturizing agent, 0.001-1% of complexing agent, 0.01-1% of surface active agent and 0.00001-0.15% of antimicrobial agent. The invention is used for the storage, sterilization, cleaning, lubrication, moisture preservation and dry resistance of the lens of the corneal contact lens and for the rehumidification of the lens, can relieve the dryness and acid bilges of the eyes, reduce the death rate of the corneal epithelial cell in a dry environment, and improve the restoration of the corneal epithelial and intradermal cells.

Description

technical field [0001] The invention relates to a composition for corneal contact lens care. Specifically, the composition is a contact lens care composition including trehalose. Background technique [0002] Contact lenses can be divided into three types: rigid, semi-rigid and soft. Rigid contact lenses are made of polymethyl methacrylate (PMMA) that is basically impermeable to oxygen and siloxane and acrylate copolymers that are permeable to oxygen. The semi-rigid contact lens is made of silicone rubber that is permeable to oxygen and can maintain the normal respiration of the corneal surface. It needs to use a special wetting solution to keep it moist; in order to meet the comfort and physiological requirements; Soft contact lenses, most commonly lenses made of polyhydroxyethylmethacrylate (HEMA). The HEMA molecule has a network structure, which enables the lens to absorb and release low-molecular liquid. The looser the network structure of the lens, the higher the wate...
