Fluorescent adhered elastomer

Abstract

A fluorescent viscoelastic agent for eye operation is prepared from a fluorescent substance and a non-fluorescent viscoelastic substance through physical and / or chemical mixing. It may have one color or the mixture of more colors chosen from white, red, blue, yellow, green, purple, and orange. It can improve the contrast and stereo feeling in visional field of doctor.

Description

technical field [0001] The invention relates to a clinical medical device, in particular to a fluorescent viscoelastic agent used in ophthalmic microsurgery. Background technique [0002] Viscoelastics are very important in ophthalmic cataract, corneal transplantation, eye trauma and other surgeries. They can protect the corneal endothelium, maintain the depth of the anterior chamber, protect the intraocular tissues, cooperate with mydriasis, prevent vitreous prolapse, help stop bleeding, support the capsular bag, and lubricate sutures, etc. The use of viscoelastic agents improves the quality and safety of surgery. Commonly used viscoelastic agents include sodium hyaluronate, methylcellulose, and chondroitin sulfate. However, the viscoelastic agents currently used clinically do not contain fluorescence, have poor visibility and attractiveness, low contrast in the surgical field, poor three-dimensional perception, low visual efficiency of the surgeon, and easy visual fatigu...

AI Technical Summary

Problems solved by technology

However, currently clinically used viscoelastics do not contain fluorescence, poor visibility and attractiveness, low contrast in the surgical field of view, poor stereoscopic effect, low visual efficiency of the surgeon, and easy visual fatigue; the viscoelastic in the anterior chamber after the operation The viscoelastic agent is not easy to be removed, and the residual viscoelastic agent in the anterior chamber can cause high intraocular pressure in patients after surgery; it cannot prevent the macular damage that may be caused by the strong light irradiation of the operating microscope

[0003] Non-fluorescent viscoelastics are widely used clinically in ophthalmology and have brought a lot of convenience to ophthalmic microsurgery, but the difficulties and complications caused by their defects and deficiencies are also very common; through searching, domestic and foreign There is no fluorescent viscoelastic at present, and no solution that can well solve the above problems has been disclosed.
