Abstract

The invention discloses an eye film agent, wherein each 1800-2200 cm2 of the agent comprises sodium azulene sulfonate 0.1-0.5g, film-forming agent 25-40g, plasticizer 5-10ml, sterilizing water 100ml, and right amount of demoulding agent, wherein the plasticizer employs glycerine, and the demoulding agent employs fluid wax, the film-forming agent is selected from polyvinyl alcohol or methylcellulose propylene glycol ether or methyl hydroxypropylcellulose.

Description

technical field [0001] The invention relates to an ophthalmic film. In particular, it relates to an ophthalmic film containing sodium azulene sulfonate which is convenient to use and has remarkable curative effect. Background technique [0002] Ophthalmic diseases such as conjunctivitis and keratitis are caused by eye infection with germs or decreased body resistance. The patient complained of ocular conjunctival injection, purulent discharge, ocular irritation, and upper and lower eyelids sticking upon waking, all of which are hallmarks of bacterial conjunctivitis. The typical clinical manifestations of keratitis include pain, photophobia, tearing, blepharospasm and other irritation symptoms, as well as ciliary hyperemia, corneal infiltration and turbidity, or corneal ulcers. Anti-inflammatory drugs and antibacterial drugs are generally used for clinical treatment of this type of eye disease, and anti-infection is one of the important measures for treatment.
