Crosslinking device for riboflavin-UV sclera crosslinking method

Abstract

The invention relates to a crosslinking device for the riboflavin-UV sclera crosslinking method. The device comprises a light source system, an operation head, and an optical fiber for connecting the light source system and the operation head, wherein the light source comprises an UAV light source and a red LED light source; the operation head comprises a light guide plate, more than one end lighting optical fiber which is fixedly connected with the rear wall of the light guide plate, and side lighting optical fibers which are fixedly connected to the left wall and the right wall of the light guide plate; reflecting films cover the upper wall, the lower wall, the left wall and the right wall of the light guide plate; the end lighting optical fibers are connected with the UAV light source; the side lighting optical fibers are connected with the LED light source. The device is high in flexibility and can achieve minimally invasive operation during performing the riboflavin-UV sclera crosslinking method.

Description

technical field [0001] The invention relates to the field of eye surgery instruments, in particular to a crosslinker for the riboflavin-ultraviolet sclera crosslinking method. Background technique [0002] Pathologic myopia (Pathologic Myopia, PM) is one of the most important blinding eye diseases in adults, and there is no good treatment strategy at present. Research on the pathogenesis of myopia suggests that the sclera is the main target organ of various pathogenic factors, and pathological weakness of the sclera is the result of pathological myopia and the cause of other related lesions. In recent years, a large number of studies at home and abroad have shown that sclera collagen cross-linking can effectively increase the biomechanical strength of the sclera and its weak areas, and it is expected to become one of the new feasible methods for the treatment of pathological myopia. [0003] Sclera cross-linking methods are mainly divided into physical cross-linking and che...

AI Technical Summary

Problems solved by technology

[0004] Previous riboflavin-UVA cross-linking studies mainly used UVA generators to remotely irradiate the target sclera area, and the eyeball needed to be pulled to expose the target sclera area. The exposure would cause great damage to the relevant ocular tissues, and the anatomical area could not be exposed. The area of ​​the sclera that is more posterior to the pole, and it is precisely this part of the sclera that is most prone to weakness and staphyloma

Therefore, the application of riboflavin-UVA crosslinking is severely limited
