LKC Technologies Makes Flash ERG and VEP Testing Easy with the RETeval™ Device
Powerful ERG Testing At Your Fingertips

ERG tests provide functional and reliable data, which matters when vision is at stake. Our transformational RETeval™ device makes ERG and VEP testing easy and readily available, providing proven and repeatable test results.

Real-Time Results for Real Patients

Same day answers with the RETeval™ device which displays real-time test results directly on the device. Make it even easier with our optional EMR SDK and customized tests for your practice. Get accurate information at your fingertips, exactly when you want it.

Affordable and Portable

Gone are the days with a dedicated room to store large, complex equipment for complete ERG testing. The RETeval™ device is small enough to fit in your hand, and delivers complete flash & flicker ERG capability at your fingertips. Perfect for multi-doctor, multi-office, or satellite office practices.


"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
