nexRef

The software hub of the Nexio ecosystem.

PC software for acquiring, reading, transforming and routing ophthalmic data. nexRef connects to nexBox devices, communicates with the Haag-Streit Refractor 900, and uniquely supports reading and writing both nexCard and NIDEK / Marco Eye Care Card workflows directly from a PC.

How it works

One PC workstation, three local flows.

nexRef keeps the refraction workstation simple: one PC, the Refractor 900 and the cards. No cloud dependency for card workflows.

Step 1

Refractor 900

RS-232 link or REST API depending on configuration.

Step 2

nexRef on PC

Local reading, writing, and data retrieval.

Step 3

Cards

Eye Care Card readable on PC.

To our knowledge, nexRef is the only public solution that can read NIDEK / Marco Eye Care Card refraction cards on a PC in 100% offline mode.
