Ultra-Precision Micro-Optics

Miniature Telescopes for the Eye

Our 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 Italian physicist Galileo Galilei, VisionCare’s implantable telescopes employ bi-convex and bi-concave convergent and divergent micro-lenses, coupled with air lenses, to create a magnified image on the retina.

Our ultra-precision micro-optical devices represent a first-of-kind technology platform: unlike large external magnification systems used to explore the outdoors or outer space, our implantable telescope technology is utilized within the eye to help improve vision for everyday activities in patients with macular degeneration and severe central vision loss. Our patients require high resolution magnification that is projected onto healthy retinal tissue surrounding the degenerated macula. The magnification helps these more peripheral parts of the retina ‘see’ the image. Clinical research trials have demonstrated that patients with End-Stage AMD enjoy clinically significant improvements in visual acuity with VisionCare’s micro-sized, 3.6mm diameter telescope implant.

VisionCare looks forward to continue pushing the technology envelope on high-performance micro-optical design and manufacturing to help even more people with severe vision disorders.
