Description

Volk Optical's 30D Lens is an essential tool for ophthalmic professionals, designed specifically for binocular indirect ophthalmoscopy (BIO) and fundus examination. This lens provides a comprehensive view of the retina, making it invaluable for both static and dynamic ophthalmic assessments.

Key Features

• Wide Field of View: The 30D Lens offers a broad field of view, allowing detailed examination of the peripheral retina. This feature is particularly beneficial for identifying retinal defects such as tears, detachments, and neovascularization.

• High Dioptric Power: With a dioptric power of 30 diopters, the lens is crafted from biconvex, aspheric glass optics, ensuring enhanced imaging quality even through small pupils. This makes it ideal for use with pediatric patients or those who cannot undergo pupil dilation.

• Non-Contact Design: Suitable for use with both binocular indirect ophthalmoscopes and slit-lamp biomicroscopes, the non-contact design enhances patient comfort and cooperation during examinations.

Optical Specifications

The lens is available in two sizes, Large and Small, each offering distinct specifications:

• Field of View: Ranges from 44° to 75° depending on the size.
• Image Magnification: Approximately 2.09x to 2.15x.
• Working Distance: Around 30 mm.

These specifications provide a panoramic retinal view, particularly useful when detail and stereopsis are less critical.

Ergonomics and Handling

The ergonomic design, with options in several ring colors, allows for easier handling and manipulation around the orbit. The Small version is particularly advantageous in pediatric or challenging cases, offering greater maneuverability.

Maintenance and Care

Proper cleaning and maintenance are crucial for the longevity of the 30D Lens. It should be cleaned with mild, pH-neutral detergent and a soft, lint-free cotton cloth. If the lens contacts the eye, high-level disinfection is required. Sterilization methods include Ethylene Oxide, Steam, and others, especially for surgical use.

Avoid using alcohol, peroxide, or acetone on contact elements, and store the lens in a clean, dry environment. A sterilization case or tray is recommended to prevent damage, and while colored rings may fade with repeated sterilization, this is purely cosmetic.

Additional Features

Each lens comes with a complimentary case and offers optional custom engraving, enhancing personalization. The 30D Lens stands out for providing a larger field of view with less magnification compared to lower-power BIO lenses, offering consistent imaging regardless of the patient’s refractive error.

Volk Optical's 30D Lens is a versatile and reliable choice for comprehensive retinal examination, embodying precision and quality in ophthalmic diagnostics.
