Abstract

The invention relates to a corneal removal amount device, in particular to a device for evaluating the corneal removal amount in a refractive operation through optical coherence elastography. The technical problem of the invention is to provide the device for evaluating the corneal removal amount in the refractive operation through optical coherence elastography, which can fix the position of a lens and can prevent the cornea of a patient from being hurt by too strong light. The device for evaluating the corneal removal amount in the refractive operation through optical coherence elastography comprises a first supporting framearranged on one side of a fixing frame and the fixing frame, a concave mirror frame arranged on the first support frame in a sliding manner, and a convex mirror frame arranged on the first support frame in a sliding manner and arranged on one side of the concave mirror frame. Through cooperation of the concave mirror frame, the convex mirror frame, a shading mechanism and a buffer mechanism, the medical staff can detect the cornea thickness of a patient more conveniently, external light can be shielded, and the detection result is more accurate.

Description

technical field [0001] The invention relates to a corneal removal amount device, in particular to an optical coherence elastic imaging evaluation corneal removal amount device for refractive surgery. Background technique [0002] When light enters another medium with a different refractive index from one medium, the direction of travel will change, which is called refraction in ophthalmology. Medical staff can use the principle of refraction to perform a series of calculations on the patient's eyes. Corneal thickness is measured to facilitate follow-up corneal surgery for patients. [0003] Doctors generally measure the patient's corneal thickness through the cooperation of light and lens, use the light to pass through the lens and irradiate the patient's eyes, and then adjust the position of the lens to record the change of light to complete the measurement work. Such an operation process is relatively cumbersome. And when adjusting the position of the lens, the lens canno...
