Problems solved by technology

[0005] Ultraviolet light-riboflavin cross-linking is currently the most important collagen cross-linking method used in ophthalmology research. Studies have proved that this method can strengthen the biomechanical strength of cornea and sclera tissue. Although the cross-linking equipment has the advantages of good stability, it generally has the disadvantages of large volume and cumbersome operation, and the existing technology mostly uses probes and other methods to irradiate the cross-linked parts in space, which requires a high degree of exposure to the eyeball sclera. , the irradiation range is also limited, and the irradiation intensity cannot be adjusted at the terminal, which lacks flexibility

Description

technical field [0001] The invention relates to the technical field of ophthalmic medical devices, in particular to an adjustable ultraviolet irradiator for ophthalmology. Background technique [0002] As a refractory eye disease with high incidence, myopia not only manifests as abnormality of the ocular refractive system, but also can be accompanied by varying degrees of damage to the visual nervous system. It has become a disease that seriously threatens global public health. Progressive myopia, as one of them, often leads to blindness due to severe pathological changes of the fundus system, which greatly threatens human health and quality of life. [0003] During the formation and development of myopia, the main pathological manifestations are sclera thinning and axial length increase. Collagen fibers in normal sclera tissue account for about 75% of the dry weight of sclera, which makes the sclera tissue have strong toughness and plays a key role in resisting intraocular...
