Abstract

The invention relates to imaging equipment, in particular to optical coherence elastic imaging equipment capable of evaluating cornea removal amount. The invention aims to provide the optical coherence elastic imaging equipment capable of evaluating the cornea removal amount, which can fix the head of a patient and does not need to be manually wiped. According to the technical scheme, the optical coherence elastic imaging equipment capable of evaluating the cornea removal amount comprises a stabilizing frame, a super-radiation light-emitting diode, an X-type optical fiber coupler, a detector, a lens placing frame and a plane mirror placing frame, the super-radiation light-emitting diode is arranged on one side of the top of the stabilizing frame, and the X-type optical fiber coupler is connected between one side of the super-radiation light-emitting diode and the stabilizing frame. The head of a patient is pushed to the middle through a second rubber clamping plate, so that the head of the patient is centered, and therefore, eyes of the patient can be conveniently evaluated and detected and are prevented from deviating from the lens placing frame.

Description

technical field [0001] The invention relates to an imaging device, in particular to an optical coherent elastic imaging device capable of evaluating corneal removal. Background technique [0002] The cornea normally refracts and focuses light onto the retina and acts as a protective barrier for the ocular components of the eye. The cornea is susceptible to a number of diseases, genetic conditions, and trauma that can lead to opacity of the supposedly optically transparent window to the retina, following corneal disease, requiring resection of the cornea and transplantation of a new donor, Before performing corneal ablation, the patient needs to evaluate the amount of cornea removal. At present, when performing corneal evaluation, the existing equipment cannot limit and fix the patient's head, which leads to the inability of the patient's eyes to be centered, which leads to the imaging results being affected. In addition, the lenses and flat mirrors are easy to be stained wi...
