  • MidVitreous Lens for Vitreolysis Applications

    Volk Optical’s Idrees MidVitreous Lens specifically designed for elimination of floaters

    Mentor, Ohio (May 11, 2015) –Volk Optical’s new Idrees MidVitreous lens provides high resolution views and maximum focusing ability to reduce required laser energy during vitreolysis treatment.

    IdreesReleaseBLOG

    Developed in collaboration with Dr. Mohammed Idrees of the Saudi German Hospital (Riyadh, Saudi Arabia), the lens was designed specifically for elimination of vitreous strands or opacities in the central mid-vitreous. With a 1.11x image magnification, and .90x laser spot, the Idrees MidVitreous Lens provides the highest resolution and focusing ability of any commercially available vitreolysis lens. Less laser energy is required for treatment, improving patient safety.

    The flanged contact provides stability for laser delivery and prevents patients from squeezing it off the eye. The large ring diameter (36mm) and tall lens body allow for easy manipulation within the orbit, particularly in patients with deep set eyes. The direct contact lens requires the use of viscous coupling fluid during laser treatment.

  • Dispatch From the Field: Terry Cooper Reports on First Leg of Uganda Mission

    Volk’s Pictor Plus earns its keep!

    It’s been a hectic but rewarding first two days in Uganda for me and the Vision 2020 team. Due to some issues with the benchtop systems, Pictor Plus ended up being our only fundus camera and it has proved to be up to the task. We’ve screened upwards of fifty patients, diagnosed a host of vision issues and even made history–not bad for just two days on the ground!

    Screening has been carried out by the Mulago Hospital staff assisted by the Royal Free Hospital Team. In just one morning clinic, we screened thirty patients, carrying out both fundus and OCT photography on each. This patient throughput is similar to that achieved in a London hospital. As patients wait for days, camping outside on the hospital grounds to be seen, it’s imperative we see as many as possible while we’re here, as well as training and mentoring the local staff.

    TC1

    Part of the reason we’ve been able to achieve such high throughput in challenging conditions has been the ease of managing patients with the Pictor Plus. With a bench top system, you have to get the patient to the chin rest with no flexibility at all in positioning. The Pictor Plus can be used on patients sitting on a regular chair, with the practitioner free to position both the Pictor Plus and the patient’s head and gaze. All three team members using it (an ophthalmologist, a retinal nurse and an orthoptist) have all expressed how much they love the ease of use and prefer it to a typical benchtop system.

    TC2

    Screening consisted of an initial Pictor Plus exam and review by an ophthalmologist. In general, we took four fundus images of each patient with Pictor Plus, disc-centered and macula-centered, of each eye. The Pictor Plus’ eyecup provides stability to the camera, reduces stray light and generally helped team members get good images. Images were then transmitted wirelessly into the Spectra Retineye screening software provided by UK-company Health Intelligence. After being acquired, the images were graded by an ophthalmologist on the team prior to, in most cases, OCT examination.

    TC3

    With our first screening exam, we made ophthalmic history in Uganda. Both the formal screening and the OCT exam were firsts for the entire country. This landmark has even attracted the attention of the national press. When you think that this technology has been available for decades, and about the volume of these exams that have been conducted in our developed countries, it is truly humbling to realize the impact of this trip.

    The first exam indicated focal laser treatment which was then carried out using a Quantel laser and Volk Optical HR Centralis lens. Over the course of the clinics, patients exhibited a range of pathologies. We saw all stages of diabetic retinopathy, as well as serious conditions such as BRVO (Branch Retinal Vein Occlusion) and CRVO (Central Retinal Vein Occlusion). In addition, we examined two patients who had pathologies suggesting they were HIV positive.

    On Thursday, we will have a pediatric consultant with us, trying out the camera on the children’s ward. They have 300 births a day here, so no shortage of patients. We will be screening for evidence of retinoblastoma and other eye disease.

    From there, I travel to the Mbarara rural clinic. I’ll be sending more updates as time allows.

  • Volk’s Terry Cooper Joins Mission to Uganda to Prevent Blindness

    Terry will bring the Volk’s Pictor Plus portable imaging capability to underserved population

    On Friday, April 24th, Terry Cooper (Volk’s Regional Manager for Europe) will embark on a 10 day charitable mission to Uganda. The Vision 2020 Links team, a group of ophthalmologists, orthoptists, and nurses from the Royal Free Hospital in London lead by consultant ophthalmologist Clare Davey, is on a mission to reduce preventable blindness in this underserved nation.

    Volk’s Pictor Plus handheld digital imager will be used primarily for diabetic retinopathy exams, as it delivers high quality retinal images with a 40 degree field of view of the fundus. It will also be used for pediatric retinoblastoma screening–particularly critical as the incidence of this childhood cancer in Uganda is much higher than that of the UK (1-2 cases referred per week in in one clinic alone in Uganda, compared to 50-60 per year in the UK).

    “I first learned about the Uganda trip when I met Clare Davey at an ophthalmology congress,” explains Terry. “As I learned the scope of the project, I realized that Pictor Plus would be great tool for the physicians on this mission. What’s more, I have a personal interest in charitable activities, so my involvement on Volk’s behalf really came together organically.”

    20150422-5S8A3130 Terry has spent this week in training with the Vision 2020 team. Here, a Vision 2020 team member practices a retinal exam using the Pictor Plus.

    The portability of the Pictor will be a huge boon for the mission, as screenings will take place both in a hospital setting in the capital city of Kampala and in a more rural clinic located in Mbarara near the border of Rwanda. The extremely compact Pictor weighs in at just one pound. The Pictor, its accessories, and a laptop with DR screening software will travel in a standard sized backpack outfitted with a solar panel for field use.

    The entire Pictor Plus system fits in a solar powered backpack. The entire Pictor Plus system fits in a solar powered backpack.

    Terry will be sending back dispatches from the field as he’s able and we’ll be documenting his trip. Like Volk Optical on Facebook (Volk Optical), or follow us on Twitter (@VolkOptical) or LinkedIn (https://www.linkedin.com/company/volk-optical) to follow Terry’s journey.

  • Accurate Ocular Measurements with the Volk Eye Check

    Volk Optical’s Eye Check, an electronic handheld ocular measurement device, aids in the diagnosis of ophthalmic abnormalities. Capable of a number of key measurements including pupil diameter, horizontal visible iris diameter, interpupillary distance, margin reflex distance, pupil eccentricity and strabismus angle, Eye Check helps practitioners screen and document ocular characteristics for contact lens fitting and general diagnostic purposes.

    The Eye Check’s intuitive user interface is easily navigated by physicians and support staff for seamless integration into the practice environment. Its real-time, accurate and objective results enable quick decision making and can be output to electronic records management systems with WiFi connectivity. Eye Check can help to quickly identify patients that are candidates for specialty lenses and reduce practice drop out rates.

    Eye Check measurement parameters that facilitate lens fitting are: • Horizontal Visible Iris Diameter (HVID) to assess correct contact lens diameter • Pupil diameter and eccentricity for GP lens fitting and multi focal contact lens choice • Lid margin to pupil margin for bifocal lens fitting

    For general diagnosis and documentation, Eye Check also measures: • Interpupillary distance for eyeglass fitting • Margin reflex distance for detection and documentation of ptosis in endocrine disorders, as well as pre- and post-surgical comparison • Strabismus angle for Amblyopia and Strabismus screening with objective documentation of strambismus amplitude

  • New Iridotomy Lens with Unique Features

    Volk Optical has launched a new specialty lens for iridotomy procedures. Developed in conjunction with Eytan Blumenthal MD, the Blumenthal Iridotomy Lens design increases access to the periphery for more efficient glaucoma treatment with less potential for damage to surrounding tissues.

    The design of the contact lens indents the cornea to open the angle and flatten the peripheral iris, delivering better patient outcomes with less post-laser inflammation. The Blumenthal Iridotomy’s precise positioning and sharply focused laser spot minimizes iris tissue collateral damage and distances the cornea from the iris to reduce the risk of endothelial cell damage.

    The Blumenthal Iridotomy lens improves over classic lenses, as it is the only lens with corneal indentation capability for enhanced viewing of the far periphery. Constructed using Volk’s patented aspheric optics, the lens delivers better image quality and improved laser burn. Lower energy is required, reducing thermal collateral damage. The large lens housing improves lens grip and alignment for oblique viewing of the entire chamber.

    Eytan Blumenthal, MD is Chairman of the Department of Ophthalmology at Rambam Health Care Campus (Hafia, Israel). This is his second lens collaboration with Volk.
