specific Embodiment approach

[0092] According to another specific embodiment of the present invention, the material used to prepare the intraocular lens in the present invention is composed of hydrophobic acrylate monomers and hydrophilic acrylate monomers, optional additives such as crosslinking agents, ultraviolet absorbers, blue light absorbers Agents, etc., obtained by polymerization. Wherein, the polymerization method is selected from bulk polymerization, preferably free radical bulk polymerization. The free radical polymerization initiator can be selected from common free radical polymerization initiators in the art, such as being selected from azo initiators, and / or peroxy initiators, preferably dilauroyl peroxide, bis(4-tert-butylcyclohexyl ) peroxydicarbonate, peroxybis(hexadecyl)dicarbonate, peroxydicarbonate ditetradecyl ester, azobisisobutyronitrile, azobisisovaleronitrile, azobisisoheptyl Nitrile, dicumyl peroxide, benzoyl peroxide, 2,5-dimethyl-2,5-bis(tert-butylperoxy)hexane, tert-butylper...

Embodiment approach

[0100] According to another specific embodiment of the present invention, when the material used for preparing the intraocular lens of the present invention contains a fluorescent agent, the fluorescent agent is fixed inside or on the surface of the final material. The fluorescent agent is stably combined in the final material. At this time, the fluorescent property of the material of the present invention can be used for medical detection. Specifically, the fluorescent material is made to fluoresce under a slit lamp light source or a Pentero microscope, and ophthalmologists can clearly, Clearly judge the adaptability of the material to the cornea, because the material will not stain the cornea when it contacts the cornea, and completely get rid of the exogenous corneal fluorescent staining agent, so that the material of the present invention can be used for medical testing without adding any additional reagents (including fluorescent agents) ).

Abstract

The invention relates to medical devices, in particular to a medical device for treating cataract, and particularly an artificial crystalline lens used for preventing and / or treating after cataract. More particularly, the artificial crystalline lens with one or more additional parts comprises a, a body, and b, an annular additional body, and the annular additional body is connected to the artificial crystalline lens.

Description

technical field [0001] The present invention relates to a medical device, in particular a medical device for the treatment of cataracts, in particular an intraocular lens for the prevention and / or treatment of post-cataract, more particularly an intraocular lens with one or more additional parts. Background technique [0002] Various reasons such as aging, genetics, local nutritional disorders, immune and metabolic abnormalities, trauma, poisoning, radiation, etc., can cause lens metabolic disorders, resulting in lens protein denaturation and turbidity, which is called cataract. With the aging of the global population, The incidence of cataracts and the total number of people suffering from cataracts are increasing. Cataract has become the world's first blinding eye disease. Among the 40-45 million blind people in the world, cataracts account for 46%. At present, there are 6.7 million cataract patients in my country, and about 1.3 million new cataract-blind people are add...
