Problems solved by technology

Antibiotic eye drops can only be used in case of eye infection, if there is no infection, it will only cause damage to the eyes
Chloramphenicol-type eye drops, because chloramphenicol has severe bone marrow suppression, pregnant women may cause serious adverse reactions to newborns, and tetracycline-type eye drops are likely to cause fetal malformations

Abstract

The invention provides a deuterium-depleted water contact lens eye lotion and a preparation method thereof, and belongs to the technical field of ophthalmic liquid medicine. The deuterium-depleted water injection is prepared from the following raw materials in percentage by weight: 0.01-3% of an osmotic pressure regulator, 0.5-2% of immobilized hyaluronic acid, 0.01-5% of a buffering agent, 0.001-1% of a surfactant, 0.001-4% of a chelating agent, 0.000001-0.0001% of a preservative and the balance of deuterium-depleted water. The immobilized hyaluronic acid can exist in the eyes for a long time and has the effects of lubricating the contact lenses for a long time, inhibiting bacteria and keeping the eyes wet, so that the problems of dry eyes, bacterial infection and the like caused by wearing of the contact lenses are effectively avoided, the addition amount of a preservative is reduced, stimulation to the eyes is avoided, and the safety of the contact lenses is improved. Wide application prospects are realized.

Description

technical field [0001] The invention relates to the technical field of ophthalmic medicinal liquids, in particular to a deuterium-depleted water eye moistening liquid for contact lenses and a preparation method thereof. Background technique [0002] With the changes in people's lifestyles and working conditions, people spend more and more time using their eyes, such as looking at computers, watching TV, playing video games, etc. for a long time, and are very prone to visual fatigue and dry eye syndrome. Eye drops have unknowingly become a must-have item for office workers. Many people drip a couple of drops from time to time to relieve discomfort. In fact, doing so is very harmful. In order to keep the sterility of the medicine and prolong the validity period of the medicine, preservatives are added to guarantee the quality. Because most of the eye drops contain preservatives, it will damage the conjunctival goblet cells in the eyes. Such as the conjunctival cup shape, if ...
