The Implantable Miniature Telescope (IMT) is FDA approved in the United States and has a CE Mark for the European Union and the United Kingdom, and a therapeutic goods certificate from Australia. Samsara Vision’s new generation SING IMT received a CE mark for the European Union in 2020 (SING IMT is not currently FDA approved).
SING-IMT is the brand name for the Tsert SI (TM) system, model NG SI IMT 3X. This is the NG SI IMT 3X implantable device packaged with the Tsert SI delivery system. The Implantable Miniature Telescope is referred to as "the IMT (by Dr. Isaac Lipshitz)" or as "the Implantable Miniature Telescope (by Dr. Isaac Lipshitz)."
Samsara Vision's expertise in ultra-precision micro-optics and machining allows us to make miniaturized telescopes that can be placed safely in the eye by an ophthalmic surgeon. Based on the principles of the seventeenth-century Italian physicist Galileo Galilei, the telescope technology platform employs first-of-kind bi-convex and bi-concave convergent and divergent micro-lenses, coupled with air lenses, to create a magnified image onto healthy retinal tissue surrounding the degenerated macula. The telescopic device and the cornea enlarge images in front of the eye approximately 2.2 or 2.7 times their normal size (depending on the model used).
The magnification helps these more peripheral parts of the retina 'see' the image viewed in straight-ahead vision by reducing the apparent impact of the blind spot. (The blind spot does not go away, but it appears smaller to the patient due to magnification.) Clinical research trials have demonstrated that the majority of suitable patients with late-stage AMD enjoy clinically significant improvements in visual acuity and visual function with Samsara Vision's micro-sized, 3.6mm diameter telescope implant. Our research will continue to push the technology envelope on high-performance micro-optical design and manufacturing to help even more people with severe vision disorders.
Resuming the ability to drive is not an expected outcome for patients.
Presently, the Samsara Vision IMT is indicated for monocular (one-eye) implantation to improve vision in the eyes of patients at least 65 years of age with severe to profound vision impairment caused by bilateral central scotomas (scars) associated with late-stage age-related macular degeneration (AMD). Patients with late-stage AMD who have undergone bilateral cataract removal and intraocular lens placement are contraindicated for telescope surgery.

The IMT is housed in a prosthetic device composed of three primary components: a 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.About Implantable Telescope Components
