Abstract:
An ophthalmic marker having a U-shaped yoke at one end of a cranked axle is disclosed. The axle is rotatable mounted with a co-axial cylindrical handle. The other end of the axle extends beyond the handle and is bifurcated. A plumb bob having a sphere and a stem is pivotally mounted on the bifurcated end of the axle. The yoke has three marker points the upper two of which are maintained in a horizontal plane by a gravitational force urging the plumb bob into a vertical plane notwithstanding the handle not being held exactly horizontal. A method of eye marking and marker making are also disclosed.
