Problems solved by technology

However, although the action of these two systems can effectively control the growth of bacteria and protect the wettability of contact lenses during storage and care, there is no perfect combination that can provide perfect intraocular performance without causing damage to ocular tissues. Harmful Polymer Combination
All current contact lens care solutions still cause some degree of damage to the tear film and tissue and membrane integrity of cells within the eye

Abstract

The present invention discloses a contact lens care composition, which contains, by mass, 0.005-5.0% of a hyaluronic acid and antibacterial peptide bonding substance, 0.1-5.0% of a non-ionic surfactant, 0.5-9.0% of an inorganic salt, 0.001-5.0% of a buffer, 0.001-2.0% of a chelating agent, and the balance of sterilized water. According to the present invention, the antibacterial peptide in the formula can provide the disinfection and sterilization effect, and with the hyaluronic acid, the wetting of the contact lens can be ensured, and the gas permeation of the contact lens can be improved; and the contact lens care composition has characteristics of broad-spectrum antibacterial property, cleaning property, moisturizing, mild formula, no irritating and high stability, can be used for cleaning, disinfecting and storage of the contact lens, and can further be used as the wetting agent when wearing the contact lenses.

Description

technical field [0001] The invention relates to a composition for contact lens care. Background technique [0002] Since the advent of contact lenses, it has been accepted by more and more people, and reports of various injuries caused by improper care and wearing of contact lenses are not uncommon. The injury caused by contact lens wearing is mainly due to the hypoxia caused by its low oxygen permeability, which leads to corneal lactic acidosis and subsequent swelling of the cornea. and changes in the integrity of the conjunctival cell membrane, and in addition to the incompleteness of the tear film. These deleterious changes in the eye tissue and tear film may also result from contact of the eye tissue with antiseptics, disinfectants, cleaning agents, and some other ingredients in contact lens care solutions. These detrimental changes can be caused by contact with the contact lens and possibly by the adhesion of contaminating solutions from contact lens care to the conta...
