Implantable Miniature Telescope
VisionCare's
lead product is the Implantable Miniature
Telescope (IMT™ by Dr.
Isaac Lipshitz), currently in Phase
II/III clinical trials for central vision loss
due to age-related macular degeneration (AMD).
This visual prosthetic device is designed to
improve vision and quality of life for
individuals with moderate to profound vision
loss caused by dysfunction of the macula. The
macula is a small specialized area at the center
of the retina that is responsible for detailed
central vision. Individuals with vision loss due
to advanced AMD encounter difficulties
performing everyday activities, since detailed
central vision is needed to recognize people,
read mail, and watch television. The telescope
implant is intended to be a permanent solution
for vision loss due to AMD.
The prosthetic telescope, together with the cornea, acts as a telephoto system to enlarge images 3X or 2.2X, depending on the device model used. The telephoto effect allows images in the central visual field ('straight ahead vision') to not be focused directly on the damaged macula, but over other healthy areas of the central and peripheral retina. This generally helps reduce the 'blind spot' impairing vision in patients with AMD, hopefully improving their ability to recognize images that were either difficult or impossible to see.
The prosthetic telescope is implanted by an ophthalmic surgeon in an outpatient surgical procedure. The device is implanted in one eye, which provides central vision as described above, while the non-implanted eye provides peripheral vision for mobility and navigation. After the surgical procedure, the patient participates in a structured vision rehabilitation program to maximize their ability to perform daily activities. Situated in the eye, the device allows patients to use natural eye movements to scan the environment and reading materials.
