Abstract

The invention relates to a corneal cross-linking device capable of individualized treatment, comprising corneal information acquisition equipment, a light emission structure, an LCD device, a bracket structure and a control computer, the light emission structure and the LCD device are arranged on the bracket structure, wherein the control computer According to the corneal lesion shape and thickness information obtained by the corneal information acquisition equipment, the light time, light intensity and light source wavelength of the light source are controlled, and the LCD device forms a personalized treatment spot, so as to achieve flexible control of the shape and depth of corneal cross-linking. The present application solves the technical problems urgently to be solved in the current corneal cross-linking, and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments for ophthalmic treatment, in particular to a medical instrument for corneal surgery, and more specifically to a corneal cross-linking device capable of individualized treatment. Background technique [0002] Corneal cross-linking therapy is a new method developed in recent years to treat corneal-related diseases. Riboflavin and ultraviolet light induce cross-linking of collagen fibers in the corneal stroma to improve its mechanical strength, thereby preventing or delaying the progression of keratoconus. In addition to being used for the treatment of keratoconus, it is also used in the preventive treatment or postoperative treatment of iatrogenic corneal ectasia, in the treatment of corneal lytic lesions, superficial corneal ulcers, and bullous keratopathy. [0003] The traditional corneal cross-linking therapy is to remove the epithelial tissue in the central corneal diameter of 5-9mm...
