Description
With a wide field of view, the Volk 28D offers visualization past the mid peripheral region up to the equator and the peripheral retina upon thorough examination. The design and power of this lens makes it a clear choice when working with patients that have smaller pupils or don't do well with dilation, such as babies or elders. The slim profile as well as a closer working distance make it easy for the doctor to easily move the lens for a quick examination, especially with patients who may not remain still for a long time. Most widely used for examination and diagnoses of Retinopathy of Prematurity (ROP) and peripheral retinal defects such as tears and detachments.

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. 
Method A: Clean with a mild, pH neutral detergent and a clean soft cotton cloth or swab. Do not use detergent with any type of Emollients.

Method B: Clean the glass element with Volk Precision Optical Lens Cleaner (POLC) or a Volk LensPen®

Method C: 
  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. 
Cleaning and Care Precautions:
  • 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.
