Volk 90D Clear Slit Lamp Lens [V90C]

The Volk 90D is the most widely known fundoscopy lens and is to date considered the gold standard in exam rooms across the world. The small profile of the 90D coupled with its optical profile makes it a great first lens. This lens is a perfect choice for general examination and retinal imaging. This lens can be used to get through small pupils for patients who do not prefer or accommodate dilation and as a result is also a popular choice for un-dilated retinal exams.

Cleaning & Care

1. Cleaning should be performed regularly to remove bodily fluids, dust, and soils from the surface of the product. 
2. Select the appropriate method of cleaning from the CLEANING METHODS Options listed below. 
3. If a product is to be sterilized prior to its re-use, Volk recommends that it first be cleaned using method C below. 

1. Prepare fresh enzymatic cleaner (e.g. Enzol) solution – 2 ounces per gallon using warm (~30-43°C) tap water. 
2. Soak each device in solution for 20 minutes. 
3. After soaking, brush knurled surface of housing with a soft-bristle brush and wipe lens portion with a soft cloth until all traces of cleaner and soil are removed. Pay special attention to all crevices and other hard-to-reach areas. Note: Do not brush lens portion to avoid scratching; use soft cloth.
4. Thoroughly rinse devices in a room temperature tap water bath (not under running water) until all visible cleaner has been removed. 
5. Transfer the devices to a freshly prepared enzymatic solution (per step 1 above) and sonicate for 20 minutes. 
6. After sonication, thoroughly rinse devices in a room temperature tap water bath (not under running water) until all visible cleaner has been removed. 
7. Inspect each device for remaining debris. If any is observed, repeat the cleaning procedure with freshly prepared cleaning solutions. 

• Whenever possible dry Volk lenses with an ultra-soft, low-lint, cotton cloth. 
• Cleaning Method C is the preferred method for cleaning Volk’s 2-piece autoclavable (ACS) vitrectomy lenses (e.g. Mini Quad ACS, Central Retinal ACS, etc.). However, the sonication step of Cleaning Method C may cause lens damage, which limits the useful life of these lenses. Use of an alternate validated cleaning method that does not include automated sonication is highly recommended by Volk Optical whenever practicable for these lenses.
