Gonnin-Amsler Marker: Precision Ophthalmic Measurement Tool

The Gonnin-Amsler marker is a specialized ophthalmic instrument designed for precise measurement of pupil distance and other critical ocular parameters. This adjustable tool features a curved scale that measures from 7.0 to 23.0 millimeters in 1-millimeter increments, providing clinicians with reliable data for accurate patient assessments. Its ergonomic design ensures ease of use during examinations, making it an essential component for eye care professionals in hospitals, ambulatory surgery centers, and clinics. The marker's robust construction supports frequent sterilization, maintaining hygiene standards while delivering consistent performance across diverse clinical settings.

• Measuring interpupillary distance (IPD) for eyeglass fitting and surgical planning
• Assessing corneal diameter for contact lens sizing and diagnostic purposes
• Supporting pediatric eye exams where small-scale precision is required
• Facilitating pre-operative evaluations in ophthalmic surgery centers

Specifications
