Breakthrough Eye Therapy

Our innovative non-viral gene therapy platform offers revolutionary treatments for eye diseases.
Innovative Drug Delivery Platform

Leveraging the Power of Electroporation

Eyevensys technology features proprietary DNA plasmids and our proprietary Electrotransfection System,
comprising an ocular device and an electrical pulse generator.

DNA Plasmids

Proprietary DNA plasmids encoding therapeutic proteins targeting retinal disease pathways are designed and produced by Eyevensys.

Electrotransfection System

Delivers DNA plasmids to the ciliary muscle cell nuclei, where therapeutic proteins are expressed and secreted, reaching the back of the eye.

BREAKTHROUGH TECHNOLOGY

Our proprietary technology enables the eye to generate its own therapeutic proteins.

OUR PIPELINE

EYS809

A novel approach for the
treatment of Wet AMD, our
platform technology enables
production of two powerful
proteins by encoding a single
plasmid.
