Description

The Volk Digital ClearField Lens is an advanced tool designed for ophthalmic professionals seeking precision in retinal examination. As part of Volk's Digital Series, this lens is tailored for binocular indirect ophthalmoscopy, offering a comprehensive view of the retina, macula, and optic nerve. Its non-contact design enhances diagnostic capabilities, making it particularly effective for detecting retinal detachments and examining mid to far peripheral retinal areas.

Key Features

• Field of View: Provides a static field of 55° and a dynamic field of 72° with eye movement, allowing for extensive retinal coverage.
• Magnification: Offers 2.79x image magnification and 0.36x laser spot magnification, delivering detailed and clear images.
• Optical Design: Features a patented double aspheric design with Low Dispersion™ glass, ensuring high-resolution imaging and improved stereopsis.
• Anti-Reflective Coating: Equipped with advanced coatings to minimize glare, enhancing clarity during examination.

Ergonomics and Handling

With a working distance of 37 mm and a lens diameter of 51.9 mm, the lens is engineered for ergonomic handling. The reduced ring diameter facilitates easier manipulation, while the optical power of approximately 22 diopters provides versatility in various clinical settings. Available in multiple colors, the lens can be personalized to suit professional preferences.

Clinical Performance

The Digital ClearField Lens offers a wider field of view and more ergonomic handling compared to traditional lenses like the 20D and 28D. It provides high-resolution views even through small pupils, making it suitable for comprehensive peripheral retinal examinations. Proper alignment with the pupil and maintaining the correct working distance are essential for optimal performance.

Maintenance and Care

To ensure longevity, the lens requires careful cleaning with mild, pH-neutral detergents and a soft cotton cloth. It supports high-level disinfection methods and is compatible with various sterilization techniques, including Ethylene Oxide and Steam protocols. Proper storage in a clean, dry environment is recommended to maintain its quality.

Additional Considerations

Users should adhere to recommended disinfectant concentrations and soak times to prevent lens degradation. Over time, colored rings may fade, though this is purely cosmetic. The lens comes with a complimentary protective case and offers optional custom engraving, adding a personal touch to this essential ophthalmic instrument.
