A kind of riboflavin-ultraviolet sclera cross-linking method with cross-linker

Abstract

The present invention relates to a riboflavin-ultraviolet sclera cross-linking method cross-linker, which comprises a light source system, an operating head and an optical fiber connecting the light source system and the operating head; the light source system includes a UVA light source and a red LED light source; The operation head includes a light guide plate, more than one end-emitting optical fiber fixedly connected to the rear wall of the light guide plate, and side-emitting optical fibers fixedly connected to the left and right walls of the light guide plate; Both the wall and the right wall are covered with reflective film; the end-emitting optical fiber is connected to the UVA light source, and the side-emitting optical fiber is connected to the LED light source. The invention has good flexibility and can realize minimally invasive operation when riboflavin-ultraviolet sclera cross-linking method is performed.

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
