Description

Technical Field

[0001] The present invention relates to the technical field of eye fixation devices, in particular to an eye fixation device used for treating keratoconus by corneal collagen cross-linking. Background Art

[0002] Keratoconus is a progressive eye disease characterized by the central or paracentral area of ​​the cornea protruding forward in a cone shape, which leads to corneal thinning accompanied by irregular astigmatism and decreased vision, seriously affecting the patient's quality of life. As the disease progresses, patients may need to wear rigid gas permeable contact lenses, intracorneal ring implantation or ultimately corneal transplantation to improve vision. However, these treatments have their limitations. For example, the comfort of wearing RGP is not good, ICRS has limited changes in corneal structure, and corneal transplantation has risks such as donor shortage and rejection.

[0003] In recent years, corneal collagen cross-linking, as an emerging non-invasive or minimally invasive treatment method, has shown significant potential in the treatment of keratoconus. This technology promotes chemical cross-linking between corneal collagen fibers through ultraviolet A light irradiation combined with the action of photosensitizers (such as riboflavin, also known as vitamin B2), thereby enhancing the biomechanical stability of the cornea and slowing down or even preventing further deterioration of keratoconus.

[0004] During corneal collagen cross-linking, it is crucial to ensure that the eye remains absolutely stable during light irradiation. Any slight eye movement may cause the light irradiation area to deviate from the predetermined position, affecting the treatment effect. In order to avoid the eye movement affecting the treatment effect, a corresponding eye fixation device is usually used on the eye to perform a fixation operation. There are many types of eye fixation devices on the market. Most of them directly block the top of the eye and stretch the eyelid outward to achieve the fixation effect. However, this type of device is generally fixed directly on the head for use. There are defects such as the front and back position, height, and support distance on the eyelid that cannot be adjusted, which affects the fixation effect, is not convenient to operate, and brings inconvenience to the user. In view of this, we proposed an eye fixation device for corneal collagen cross-linking to treat keratoconus. Summary of the invention
