Please contact us if you cannot find an answer to your question.

What is EyeStream?

EyeStream is a digital imaging upgrade module for slit lamps that transforms a traditional slit lamp into a fully functional digital imaging system. It enables high-quality image capture and video recording without replacing the existing equipment.

Do I need to replace my existing slit lamp to use EyeStream?

No. EyeStream is an external upgrade system designed to be mounted on compatible slit lamps. It allows clinics to upgrade to digital imaging at significantly lower cost compared to purchasing a new digital slit lamp.

Which slit lamps are compatible with EyeStream?

EyeStream is compatible with most major slit lamp brands, including Haag-Streit and Topcon-style systems, as well as other standard upper-light-source slit lamps.

Compatibility depends mainly on:

Microscope structure
Magnification system (typically 3x or 5x drum systems)
Physical mounting space

What imaging modes does EyeStream support?

EyeStream supports multiple clinical imaging modes, including:

Diffused illumination for general anterior segment observation
Slit illumination for detailed structural examination
Meibography mode for meibomian gland imaging

These modes cover routine slit lamp examination and dry eye diagnostics.

What is Meibography used for in EyeStream?

Meibography mode uses infrared illumination to visualize meibomian gland structure. It is used for:

Dry eye disease evaluation
Meibomian gland dysfunction (MGD) assessment
Longitudinal disease monitoring and follow-up comparison

What is the purpose of the yellow filter?

The built-in yellow filter enhances fluorescein staining visibility by:

Increasing contrast of corneal staining patterns
Reducing background light interference
Improving tear film break-up time (TBUT) observation
Supporting contact lens fitting assessments

Does EyeStream support voice control?

Yes. When used with VisuDoc software, EyeStream supports voice-activated operation, enabling hands-free control during examinations.

Typical voice commands include:

“Capture” – take a photo
“Video” – start recording
“Stop” – stop recording
“Slit / Diffusion / Meibo” – switch imaging modes

This improves workflow efficiency and reduces interruptions during clinical exams.

How are images and videos stored and managed?

All captured data can be stored in the VisuDoc system, allowing:

Structured patient record management
Longitudinal follow-up comparison
Clinical documentation and reporting
Improved doctor–patient communication

What image and video quality does EyeStream provide?

EyeStream delivers high-resolution clinical imaging, including:

8MP imaging sensor
Up to 4K image resolution (3840 × 2160)
1440p video recording at 30fps
JPEG image and MP4 video output formats

Is EyeStream suitable for dry eye clinics?

Yes. EyeStream is specifically designed to support dry eye diagnosis and management, including:

Meibography for gland evaluation
Fluorescein cornea staining observation
Tear film analysis
Long-term disease monitoring

Is installation complicated?

No. Installation is straightforward:

The module is mounted onto the slit lamp
Connected via USB to a computer
No replacement of optical components is required

Is EyeStream useful for teaching and patient communication?

Yes. EyeStream is widely used for:

Medical education and training
Real-time patient education
Visual disease explanation
Before-and-after treatment comparisons

It significantly improves patient understanding and treatment acceptance.
