Problem: Current vision screening devices are costly, require large spaces for use, and need to be supervised by trained staff,

which limits testing productivity and creates long wait-times.

With worsening manpower shortages, existing infrastructure does not have a saleable approach to meet the increased demand for vision testing.

 

Screening equipment is bulky and expensive
→ costly to expand vision testing to more sites

Visual acuity test requires space
→ limits testing output in small clinic space

Manual vision screening
→ more manpower is needed to support greater demand for tests

AVAT 1.0 Clinical Performance

 

Pinhole Testing

 

Why AVAT?

  • Afocal lens technology and adaptive computer algorithm provide clinical-grade accuracy, validated at public eye specialist centres in Singapore.
  • Small physical footprint – 4 times reduction in size means more VA testing can be performed without increasing floorspace or manpower.
  • Easy, intuitive test workflow for self-testing with minimal or no supervision eliminates the need for skilled operators to administer test.
  • VA testing can be performed at any time in hospitals and community (schools, GPs) to offer comprehensive, convenient screening.
  • Results can be seamlessly integrated in existing electronic medical records or secured cloud storage for easy retrieval and removes human error.

Deployment Strategy

AVAT is the game changer in hongkong

AVAT addresses the increasing demand to decentralise the existing care model of conducting eye screening and monitoring of eye diseases. By incorporating automation and digitalisation, AVAT has allowed for more efficient vision testing workflow with minimal costs and manpower resources.

  • Freeing up space, manpower resources
  • Allowing self-administered testing with no supervision
  • Require small footprint
