VisionCare™ CentraSight® Implant for End-Stage AMD

Implantable Miniature Telescope.

The CentraSight treatment program uses a tiny telescope (Implantable Miniature Telescope by Dr. Isaac Lipshitz) that is implanted inside the eye. The telescope implant is a Health Canada & FDA-approved medical device that works like a telephoto lens of a camera. Once implanted inside the eye, it magnifies images onto the healthy areas of the light-sensing retina to help improve central (straight ahead) vision. The CentraSight treatment program has been developed to help patients follow the necessary steps for proper diagnosis, surgical evaluation, and postoperative care.

Implantable Telescope Technology

The Implantable Telescope Technology platform is based on wide-angle micro-optics that, in combination with the optics of the cornea, create a telephoto system that magnifies objects in view. VisionCare’s third-generation telescope implant (Implantable Miniature Telescope by Dr. Isaac Lipshitz), has received FDA approval. The company also holds a CE mark and Israel Ministry of Health approval for distribution and sale of the device. The telescope implant is surgically placed in the capsular bag after removal of the eye’s lens. Implantation inside the eye allows the patient to see using natural eye movements in both stationary and dynamic environments.


The Implantable Telescope Technology is housed in a prosthetic device composed of three primary components: a fused quartz glass capsule that contains wide-angle micro-optical elements; a clear polymethylmethacrylate (PMMA) carrier; and a blue PMMA light restrictor. The sealed optical component is snap-fitted into the carrier plate.
