LipiView II Ocular Surface Interferometer
Leading innovation in lipid layer thickness measurement and meibomian gland imaging
LipiView® II Ocular Surface Interferometer with Dynamic Meibomian Imaging™ (DMI) measures lipid layer thickness (LLT) with nanometer accuracy, captures blink dynamics, and images meibomian gland structure.
The LipiView II Interferometer features patented technology that provides a sophisticated assessment of factors that contribute to dry eye. Compelling visuals and video captures provide a unique opportunity to educate patients about their personal ocular health.| Patent Information
LipiView II Features
Real-time visualization of the lipid layer to evaluate the dynamic response of lipids to blinking
Patented noise canceling technology to measure sub-micron thickness of the lipid layer
Video and analysis of blink dynamics
High-definition imaging with Dynamic Meibomian Imaging
Dynamic Meibomian Imaging
Meibomian Glands in High-Definition
Surface lighting originates from multiple light sources to minimize reflection.
Changes to the light intensity across the surface of the illuminator compensate for the lid thickness variations between patients.
LipiView II Reporting
Visualize and Analyze Blinks
Analyze Blink Patterns
Computerized analysis of blink patterns objectively quantifies the number of complete and partial blinks. Results are displayed in a frame-by-frame graphical representation that shows fluctuations in lipid thickness measurements between each blink. A video capture allows clinicians and patients to review blinking habits during consultation.
Visualize Blink Response
High-resolution video depicts how well ocular lipids disperse in response to a blink through variations in light patterns reflected off of the tear film called an interferogram. The system enhances the interference pattern and displays a profile corresponding to an interferometry color scale which has been validated to a known standard for lipid layer thickness measurements with a precision of 1 nm and an accuracy of ±10 nm.
