Customization and Accessories

The Volk 78D Lens is available in a variety of ring colors, including Black, Blue, Gold, and more. Custom engraving options are available, allowing up to 14 characters on the lens and up to 17 on the case. It comes with a single lens case or a presentation case for secure storage.

Maintenance Guidelines

To maintain optimal performance, the lens should be cleaned with lukewarm or distilled water and a gentle, pH-neutral soap. It should be dried with an ultra-soft, low-lint cotton cloth. For disinfection, high-level disinfectants are recommended, and several sterilization methods are suitable, excluding autoclaving or boiling.

Additional Considerations

The lens is designed for use by licensed physicians and is effective for examinations with both dilated and undilated pupils, though dilation is recommended for optimal imaging. The cosmetic discoloration of colored rings due to sterilization does not affect functionality, ensuring long-term reliability.

Widely trusted in clinical practice, the Volk 78D Lens continues to be a preferred choice among ophthalmologists for its exceptional imaging capabilities and robust design.
