Description

Technical Field

[0001] The present invention relates to the technical field of corneal detection equipment, and in particular to a corneal detection equipment with macro detection and free-angle real-time display. Background Art

[0002] Corneal pachymeter is used for corneal astigmatism, corneal dystrophy, corneal edema, and accurate measurement of corneal thickness. At present, corneal pachymeter is mainly used for preoperative examination and postoperative efficacy evaluation of refractive surgery, namely radial incision, excimer laser refractive ablation, and excimer laser in situ mileibrio. Refractive surgery changes the curvature in different ways to achieve the purpose of correcting refractive errors.

[0003] The existing corneal thickness meter has a detection line. Since the detection line is too long, the detection line is still placed in a disorderly manner after being inserted into the detection hole, which can easily cause the detection line to be tangled and scattered. Therefore, it is necessary to design a new corneal thickness meter.
