Davis plumb-bob 4-ray pre-op corneal gravity marker solomon 4 7/8 marks 3," 6," 9," and 12 o'cloc 20.0 cm (8.0)

Davis Plumb-Bob 4-Ray Pre-Op Corneal Gravity Marker

The Davis plumb-bob is a specialized ophthalmic instrument designed for precise pre-operative marking of the cornea. This gravity-based tool features four distinct rays marked at the 3, 6, 9, and 12 o'clock positions, ensuring accurate vertical alignment during surgical planning. With a total length of 20.0 cm (8.0 inches), it provides sufficient reach and stability for clinicians in busy operating rooms and ambulatory surgery centers. The instrument relies on natural gravity to establish a true vertical axis, minimizing human error in rotational alignment. Its robust construction supports repeated sterilization cycles, making it a reliable staple for eye care facilities requiring consistent, high-precision corneal orientation before procedures.

• Pre-operative corneal marking for astigmatism correction
• Establishing vertical axis alignment in cataract surgery
• Rotational calibration for toric intraocular lens placement
• Standardizing patient positioning in outpatient clinics

Specifications

• Clean with mild detergent and water after each use to remove residue.
• Inspect regularly for bending or damage to the plumb line mechanism.
• Store in a dry, protected case to prevent corrosion of metal components.
• Verify vertical accuracy periodically using a calibrated level.
