RETeval Device

“Facing the pandemic of COVID-19, I appreciate the use of RETeval® and other portable devices to minimize the patient’s movement to too many rooms, thus hopefully limiting the spread of disease.”

– Dr. Igor Kozak, specializing in Vitroretinal Surgery, Medical Retina and Uveitis at Moorfields Eye Hospital Abu Dhabi


“We have been very pleased with the RETeval. It has changed the way that we practice and has allowed us to significantly decrease the amount of EUAs with ERGs we perform. Furthermore, it has resulted in earlier diagnosis of patients with inherited retinal degenerations.”

– Melanie Schmitt, MD, University of Wisconsin School of Medicine and Public Health


“There is a COVID19 positive little girl on the ward who needs an ERG to help with a possible NCL diagnosis, so that will be my first attempt of an ERG wearing full PPE!”

– RETeval® User


“The handheld and portable nature of the device made it easy to bring to multiple office locations. We were able to test many patients at once, and gathering information was seamless for our technicians and patients. We have been able to see more patients and get better information on their retina function since acquiring the RETeval device last year. Our patient profile is improved since we are bridging the gap between structural and functional information, allowing us to see a full picture of eye health.”

– Robert Feig, MD, Brooklyn Eye Center – Retina Specialist


“The RETeval  device brings my practice a truly portable, easy to use ERG solution. We have the option of obtaining a standard ERG with skin electrodes or corneal electrodes. We were impressed with the ease of acquisition, the quality of the automatic reporting function and the affordability. The ability to download reports into our EMR facilitates timely record keeping and communication with referring doctors. We appreciate the overall quality of the device.”

– Dr. Monique Leys, MD EBO, West Virginia University Eye Institute


“I have been using RETeval for about 4 months and in this short time I was able to implement ERG with minimal disruption to the clinic. The exams are done by our excellent nurse and she reports that the patients are really cooperative.”

– Dr. Igor Kozak, specializing in Vitroretinal Surgery, Medical Retina and Uveitis at Moorfields Eye Hospital Abu Dhabi


We plan training sessions and visits by patients implanted with a RETINA IMPLANT Alpha AMS subretinal implant(*) in their own home environment. This allows an individualized training adapted to the requirements of each implant user. It also requires a lot of flexibility. Thus, to evaluate our Corneally Recorded Implant Responses outside the clinic or a lab we need a small, easy to handle and flexible diagnostic tools. The RETeval has turned out to be a smart and helpful system for having a quick check of the implants’ electrical output.

*RETINA IMPLANT Alpha AMS is a FDA non-approved medical device. RETINA IMPLANT Alpha AMS is a CE-marked product.


RETevet Device

“I enjoy the RETevet’s ease of use and portability. The first time I started the device I was able to perform an ERG with no help at all from LKC. We are now performing ERG tests with RETevet in patients with no sedation at all if it is indicated or owner denies sedation.”

– Martí Cairó Font, DECVO Ophthalmologist, Hospital Veterinari Canis – Girona, Spain


“I added the RETevet device to my practice because of the ease of use, portability, and ability to get repeatable test results. In my experience, LKC products have less variability in test results, making the RETevet perfect to use between my practice locations to get the same results for all our patients. In my mind, the RETevet is superior to other systems in the field, both with respect to accuracy and reproducibility, and with an ease of interpretation that is surpassed by none.”

– Dr. Robert J. Munger, DVM, DACVO, Animal Ophthalmology Clinic, Ltd.


“As someone not familiarized with ERG, I was surprised with how easy it is to perform ERG tests with the RETevet. The real time view of the patients eye during testing and the way the device monitors electrode connection allows me to control all crucial parameters for successful measurement.  I can perform most of the light-adapted tests without sedation of anesthesia with ease due to the fast and efficient testing protocols.”

– Kaisa Wickström, Veterinarian, Eläinlääkäriasema Kamu Oy – Oulu, Finland


“Our organization has implemented the RETevet device at multiple locations. The ability to visualize the animal’s eye throughout the entire procedure ensures proper electrode placement, more accurate testing, and minimal downtime between patients. The device has significantly less background interference which allows our patients to be tested without sedation. These features enable our staff to test more animals in an affordable manner. We are impressed with the performance and capability of LKC’s RETevet device.”

– Frank J. Frassetto III, ACHE, BSHM, CRT., Chief Operating Officer, Eye Care for Animals


“I improved my skills under the guidance of the most outstanding European veterinary ophthalmologists, Prof. Dr. Peter Bedford (Royal College of Veterinary Sciences London) and Prof. Dr. Alain Regnier (Ecole Nationale Vétérinaire de Toulouse) and I am a member of ESVO (European Society of Veterinary Ophthalmology). I have a wide range of diagnostic and surgical instruments and when it comes to electrophysiology, I carry out examinations of the retina using the extremely modern RETevet device, which allows performing an ERG examination without general anesthesia.”

– Piotr Dąbrowski, Veterinary Doctor, Surgeon – Poland


UTAS Systems

 “I have been a loyal LKC customer for over 20 years. I started with the UTAS system for ERG testing to determine not just surgery candidacy for patients with cataracts, but also to thoroughly evaluate retinal function in cases with retinopathy and vision loss. I added the RETevet device to my practice because of the ease of use, portability, and ability to get repeatable test results. In my experience, LKC products have less variability in test results, making the RETevet perfect to use between my practice locations to get the same results for all our patients. I also took advantage of the fact that LKC could help me create customizable testing protocols for my practice needs, including a scotopic patient test set. The device is a great addition to my ERG testing capabilities, and the combination and comparability of the UTAS and RETevet systems give my practice capabilities that exceed those of many practices. It provides the optimal results for my patients and their owners with a convenience that is unparalleled. I am confident that our testing is the best in our area. LKC’s great customer service and commitment to quality have kept me as a repeat customer for decades. In my mind, the RETevet is superior to other systems in the field, both with respect to accuracy and reproducibility, and with an ease of interpretation that is surpassed by none.”
