Problems solved by technology

Usually, the treatment options for keratoconus include: corneal stromal ring implantation, corneal deep lamellar transplantation or penetrating keratoplasty. Although the above treatment options can improve the biomechanical strength of the cornea, they are limited to the treatment of the cornea that has already sent lesions and cannot solve the problem. fundamental defect in the cornea

Embodiment Construction

[0027] The technical scheme of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] The corneal cross-linking instrument of the present invention is equipped with a lens group in the lens barrel, which can eliminate the stray light and astigmatism of the light beam caused by diffraction, so that the brightness of the light spot formed by the light beam emitted by the light source is uniform and the edges are neat, meeting the treatment needs of different people.

[0029] The invention is a corneal cross-linking surgical instrument, comprising a high-power light source (1) fixed on the light source base (2) through a top wire and a light adjusting disc (4) installed in the middle of the light source base (2); A lens one (7) and a lens two (8) are installed in the light source base (2), a lens mounting seat (10) is linked under the light source base, and a lens three (11) is provided at the lower part of the lens mounting...

Abstract

The invention belongs to the medical appliance technical field and relates to a corneal cross-linking instrument. The corneal cross-linking instrument comprises a light source; the light source is installed at the upper part of a light source base; the middle of the light source base is provided with a light adjustment disk and a lens group; the lower part of the light source base is connected with a lens mounting seat; and the lower part of the lens mounting seat is provided with a lens. With the corneal cross-linking instrument of the invention adopted, stray light of a light beam can be eliminated, so that a light spot formed by a light beam emitted by the light source can be uniform, and the edge of the light spot is neat, and the size of the light spot is adjustable.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a corneal cross-linking instrument. Background technique [0002] The cornea is a layer of transparent membrane located on the front wall of the eyeball, accounting for about 1 / 6 of the fibrous membrane. The cornea is perfectly circular when viewed from the back, and horizontally oval when viewed from the front. The cornea covers the iris, pupil, and anterior chamber and provides most of the refractive power of the eye. [0003] Keratoconus is a corneal lesion characterized by dilatation of the cornea, causing the central portion of the cornea to protrude forward, thinning into a conical shape, and producing a high degree of irregular astigmatism. Keratoconus is a common disease that occurs mostly in teenagers, which can lead to irregular astigmatism, high myopia, severe vision loss, and acute corneal edema and scarring in severe cases. Usually, the treatmen...
