This sight-saving technology, better known as OCT, underpins the diagnosis and treatment of every major eye disease, as well as being used to screen for numerous non-eye-related illnesses, such as diabetes and multiple sclerosis.

However, OCT systems are confined to specialist environments due to the size and fragility of the underlying optical hardware, heavily restricting access. Our photonic chip technology compresses a tabletop-worth of mirrors, lenses and fibre-optics onto a single piece of material smaller than a coin. Like the chips that power your phone, these are mass-manufacturable and can be used anywhere on or off planet Earth.

Siloton’s photonic chips are core to a new generation of portable eye scanner, delivering OCT at scale. Our core focus is on developing a complete ophthalmic OCT system for use in the clinic, community, and home. Since 2025, we have also started to make our chip technology available for use in other market segments, through our OCT-Chip Development Kits.
