Tear Film Imager Technology

The TFI uses spectral interference to image the corneal surface with a large field of view and high lateral resolution.

Mode of Operation

  • The TFI conducts an analysis of broadband, low contrast, light reflectance from ultra-thin layers.
  • The TFI has a spectral-model-based interpretation of the reflectance.
  • The TFI has a full field imaging over a large field of view > 6.25mm.
  • The TFI conducts an analysis of broadband, low contrast, light reflectance from ultra-thin layers.
  • The TFI has a spectral-model-based interpretation of the reflectance.
  • The TFI has a full field imaging over a large field of view > 6.25mm.

Device Attributes

The TFI measures and can report the following while the patients blink naturally

All muco-aqueous layer thickness parameters (MALT). These specifically include:
  • Evaluation of the muco-aqueous thickness layer (MALT) over time.
  • Evaluate the average muco-aqueous thickness layer (MALT).
  • Evaluate the muco-aqueous layer thickness change rate (MALTR).

All measurements are at nanometers resolution.
The TFI non-contact measurement allows regular blinking to preserve tear film dynamics.

Lipid layer thickness Parameters

  • The TFI evaluates the dynamics of the lipid layer thickness (LLT) over time
  • Evaluates the lipid layer thickness (LLT) over a large field of view >6.25mm
  • Evaluates the average lipid layer thickness (LLT)
  • Evaluates the lipid breakup time (LBUT)
  • Evaluates lipid map uniformity

Lipid layer maps demonstrate the significance of the lipid layer uniformity, which plays an important role in maintaining tear film health.
The TFI produces a 3D map of the lipid layer over a large field of view > 6.25mm.

Mean Blink Frequency

  • The TFI evaluates the interblink interval (IBI) and is measured in seconds.

Measurements performed during natural blinking.

The only device to simultaneously measure the muco-aqueous and lipid layers

The TFI presents imaging of the corneal surface with a very large field of view and a high lateral resolution.
  • The TFI provides the thicknesses of the tear film’s muco-aqueous and lipid inner layers with a nanometers-level resolution.

The thicknesses are measured at a very high rate. The spatial and temporal resolutions enable the reliable calculation of the dynamic properties of the tear film.
