Today’s lesson: Cleaning Non-Contact Exam Lenses. Read on for some do’s and don’ts of how to keep your Volk BIO and slit lamp lenses clean and clear for the best possible imaging. Regular care to remove smudges, oils, make-up, lint, and water spots will keep your non-contact lenses in great shape for years to come.

Do:

  • rinse lens under warm running tap water.
  • use a very soft, non-abrasive sponge, with a mild detergent, such as Dawn soap, to gently clean the lens surface.
  • clean lens one side at a time in a clockwise direction. Cleaning in a counter-clockwise direction may loosen the glass element from the ring over time.
  • dry the lens with a low-lint cotton, or cotton-synthetic towel. Old school baby diapers are a great choice. Microfiber cloths can be used to dry a wet lens, as long as the microfiber cloth and the lens are clean.

Don’t:

  • scrub hard or rub the lens surface with force. This could cause damage to the anti-reflective coating over time.
  • use microfiber cloths on a dirty dry lens. They can be used only if clean, to dry a clean, wet lens.
  • dry lenses with paper products such as napkins, paper towel, or Kim Wipes as these may scratch the lens surface over time.
  • air dry your lens; water droplets left to dry on the surface of the lens may deposit hard water minerals which will cause damage to the coating.

For quick, convenient cleaning, Volk also offers the Lens Pen and Precision Optical Lens Cleaner (POLC) wipes. The Lens Pen has a lint brush on one end and a carbon-fiber tip to gently remove smudges on the other end. Always be gentle with the Lens pen! POLC wipes are pre-moistened with an ethyl alcohol cleaning solution that dries instantly.

Vold M.D. and Transcend Medical Inc., the TVG lens has been designed specifically for MIGS and all intraoperative gonioscopy procedures.

“Volk Ophthalmic Lens Review” featured on EyeGuru.org

“By Residents, For Residents” is the motto of EyeGuru.org, providing essential information to ophthalmology residents, from Residency Essentials guides to Flashcard Decks. The site’s latest blog post, written by site co-founder Dr. David Xu, a second year ophthalmology resident at UCLA, tackles the common question many residents face: “Which lenses should I buy?” It’s an important one; lenses are a significant cost to newly minted ophthalmologists, so you want to invest in lenses with the utility, performance, and quality to last you for years to come.

In his post, David reviews several of our slit lamp lenses, BIO lenses, and gonio lenses, comparing the magnification, field of view, application, and ease of use for each type of lens, and recommending his preferred choices. He even breaks down key lens parameters in a handy comparison chart.

While we did provide loaner lenses for David’s evaluation, he did not receive any other benefit from Volk, and all views and opinions in his post are his own.

Laser Lens Optimized for Vitreolysis Procedures

Volk Optical’s new Singh MidVitreous Lens improves patient comfort during elimination of floaters


Mentor, Ohio (August 31, 2016) – Volk Optical’s new Singh MidVitreous lens provides high resolution views with doctor-designed features that improve treatment efficiency and patient comfort during laser vitreolysis treatment.

SinghRelease

 

Developed in collaboration with Dr. Inder Paul Singh, the lens was specifically designed for elimination of vitreous strands or opacities in the near & central mid-vitreous. With a 1.16x image magnification, and .86x laser spot, the Singh MidVitreous Lens provides the highest resolution and focusing ability of any commercially available vitreolysis lens. Less laser energy is required for treatment, improving efficiency and safety.

A compact design facilitates lens placement, particularly in children and patients with small eyes. The small flanged contact increases patient comfort by providing stability throughout vitreolysis, which typically lasts longer than other laser procedures. The design prevents patients from squeezing the lens off the eye, and reduces the amount of manual pressure the doctor needs to apply in order to maintain coupling. The 30-mm ring diameter and short 24-mm lens body allow for easier slit lamp handling, with slightly more imaging depth range than a taller lens. The direct contact lens requires the use of viscous coupling fluid during laser treatment.

For more information on the Volk Singh MidVitreous lens, visit www.volk.com or phone Volk at 1-800-345-8655.

Volk University: Lenses, Lenses and More Lenses

Welcome to “Volk University” where we invite you to learn more about the selection, use and care of your favorite Volk products.

Today’s lesson – Lenses. What’s special about Volk lenses and what’s the difference between the more than 180+ lens options we offer.

 

Volk Lens Basics

  • Volk lenses are aspheric on both sides of the lens-many other lenses are only aspheric on one side. An aspheric surface delivers a crisper image to eliminate distortion. Volk’s double-aspheric lenses eliminate more distortion for better overall imaging.
  • The Diopter value of a lens is a unit of refractive power of an optical lens, and is denoted by the inverse of the focal length of the lens.
    • A lens with a higher Diopter power provides a wider field of view, lower magnification, and the best performance through small pupils.
    • Lenses with a lower Diopter power have a narrower field of view, higher magnification, and do not perform well through a small pupil.

 

  • Lens orientation makes a difference.
    • Double aspheric lenses are not always symmetric on both sides. A lens with asymmetric aspheres will produce different optical results depending on which side of the lens you look through. Therefore, proper orientation is required for peak performance.
    • The Volk “V” is like an arrow and is designed to point towards the patient. Orient your lens with the point of the V pointing at the patient.
    • Some lenses have a silver rim on one side of the ring – the silver rim is another indicator of orientation. The silver rim should always be on the side of the lens closest to the patient.

 

  • “Working distance” (distance of the lens to the patient’s eye) varies by lens. Ensuring the lens is at the right focal length will ensure the finest clarity, depth of focus, and field of view. Refer to your lens’ instruction manual, Volk’s website, or a Volk catalog for listings of working distances.
  • Most lenses are optimized for use at lower slit lamp magnification settings. Increasing the slit lamp magnification may introduce image distortion and aberrations.
    • Suggested slit lamp magnification power for Volk lenses is 6x– 16x, where 10x is the optimal mag. 25x and 40x are too high and will likely cause distortion in the image.
