Comprehensive electrophysiology system transforms eye care, enabling ophthalmologists and optometrists to conduct tests to assess vision-threatening diseases with ease

GAITHERSBURG, MD, January 11, 2017LKC Technologies once again leads through innovation as the RETeval™ device, LKC’s full function flash ERG/VEP system, was granted a patent (USPTO # 9,492,098 B2) on November 15, 2016 for its exclusive innovative stimulus generation, and another patent (USPTO # 9,510,762 B2) on December 6, 2016 for its LKC Sensor Strip skin electrode arrays. The patents further solidify LKC Technologies’ commitment to innovation and dedication to quality. These patents have far-reaching implications in bringing full ERG functionality closer to the patient, as the products enable physicians and researchers to better utilize visual electrophysiology to evaluate retina function in the assessment, diagnosis, and monitoring of a variety of vision-threatening diseases.

“Today’s eye care professionals want repeatable, accurate test results and easy to use systems that help them understand what is going on with their patients,” said LKC Technologies President and patent author, Jim Datovech. “While the RETeval™ device is designed to utilize traditional corneal based electrodes, certain clinical settings benefit from the less invasive skin electrodes. We are especially proud of LKC’s Sensor Strip skin electrodes, which are easy to use, cost effective, and more efficient than other skin electrode options. These patented electrode arrays enable easier electrical connections with reduced bending stiffness, which results in less room for error and more effective usage. Where warranted, patients appreciate the non-invasive nature of these electrodes and fast ERG testing with the RETeval™ device, and doctors appreciate the reliability and repeatability of ERG results using the device, regardless of their choice of electrode.”

The RETeval™ device is LKC Technologies’ handheld visual electrodiagnostic system that features a complete solution for ophthalmologic flash Electroretinogram (ERG) and flash Visual Evoked Potential (VEP) testing. Flash ERG and flicker ERG testing is helpful when used to diagnose or treat patients with glaucoma, diabetic retinopathy, CRVO, pediatric nystagmus, and much more. The RETeval™ device is the world’s first non-invasive hand-held, full function ISCEV protocol-compliant visual electrophysiology device that utilizes skin or corneal electrodes on dilated or un-dilated eyes. Completely portable, the device is useful for any research or clinical setting, including a multi-office practice.

Datovech further stated that, “It is particularly gratifying that customers around the world are utilizing nearly 600 installed RETeval™ systems in their daily practice with a high level of satisfaction and effectiveness. Flash ERG/VEP test results provide functional information that was previously not easily or readily available to assist in the diagnosis and treatment of a variety of diseases. Utilizing the RETeval™ device unlocks the availability of ERG/VEP based functional information in a clinical setting.”

“Using our patented Sensor Strips enables comprehensive and accurate testing that is easier for both the operator and patient. The sensor strip has all three required electrodes and is placed on the skin in a one-piece strip. The electrical connection to the strip is a simple clip that can be operated with one hand,” said LKC Technologies COO and inventor Quentin Davis. “Customers have reported that LKC’s Sensor Strips are easy to apply and are well tolerated by patients, which is particularly helpful in the pediatric market and for patients who do not tolerate corneal electrodes well. Our Sensor Strip electrodes offer similar test repeatability comparable with corneal electrodes.”

Compared to other skin electrodes on the market for ERG testing, the LKC Technologies’ Sensor Strips have the following benefits:

  • Inclusion of all three necessary electrodes in one array, making placement of all electrodes easier and more consistent in clinical use
  • All connections done simultaneously with one connector, making it impossible to misconnect the electrodes to the device
  • Patented torsion-relief feature of LKC’s Sensor Strips and automatic electrode clip disconnection feature reduces the chance of the connector or cable inadvertently pulling the electrode off of the skin due to patient movement or environmental factors
