Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a cornea marking device. Background Art

[0002] Corneal marking is a necessary step in ophthalmic surgery for implanting an intraocular lens. Currently, doctors typically use a slit lamp to determine the axial position, scratch the corneal limbus with a syringe needle, and then use a marking pen to position the cornea. This marking method relies heavily on the doctor's personal experience and places high demands on the marker's technique. Corneal markers are currently available on the market, most of which use positioning discs and marking pointers. While these devices can complete corneal marking, their overall operability is relatively low and inconvenient. Therefore, the design of a new corneal marking device has become a research trend in this field. Utility Model Content
