Acquisition and image processing
Sagittal Anterior Map
Sagittal Anterior Map gives information about Radius and diopter information of each point with respect to optical axis of the eye
Tangential Anterior Map
Tangential Anterior Map gives information about Radius and diopter information of corneal surface measured instantaneously


Refractive Anterior Map
Refractive Anterior Map gives total corneal refractive power Provides single and dual multimap view with preferred scale customization
Anterior Elevation Map
Anterior Elevation Map gives detailed information about the shape and contour of the cornea. It determines areas of elevation or depression relative to a reference shape


Zernike Analysis
Zernike analysis for refractive information from spherical to higher order aberrations

Dry Eye analysis
All-in-one unit- a complete solution for all dry eye examination needs
Cartesia is equipped with extensive dry eye examination module which consists of key dry eye evaluation procedures like
Meibography
Tear meniscus height analysis
Tear film breakup time

Meibography
Infrared Visualization
IR rays facilitates the detection of Meibomian Gland Dysfunction (MGD) which occurs due to lipid layer deficiency of the tear film using infrared light
Automated analysis
Automated analysis of the image simplifies the diagnosis process for the user
Easy interpretation
The results would be a displayed in comprehensive, color-coded grading framework which is quick

Tear meniscus analysis
Severity grading with colour coding aids in clear Identification of the condition
Quantitative and qualitative measurement of tear meniscus
Tear volume and tear film status can be measured using Tear meniscus height (TMH)
Accurate auto-segmentation of Tear meniscus
Precise meniscus height displayed in millimeters

Non invasive tear film breakup time
Tear film stability assessed with non-invasive tear breakup time analysis
Quantitative and qualitative measurement of tNon-invasive nature of testing eliminates the need for fluoresce-in staining thereby the tear film remains unaltered prior to measurementear meniscus
Testing experience with zero irritation or discomfort for patients
One click video capture makes the acquisition easier
Effortless Data Visualization
Offers graphical mapping with first breakup time and average tear breakup time
Intuitive time graph- Easy tracking of tear film stability over time



Non invasive tear film breakup time

TMH Comparative Report

Pupillography
Capable of dynamic pupil measurement and analysis under Photopic (40 Lux), Mesopic (4Lux) and Scotopic (0.04 Lux) conditions
Crucial pre-operative measurement in case of refractive surgery or multifocal IOL implantation
Angle kappa
Angle kappa can be measured in terms of Cartesian and polar forms, under different lighting conditions: Photophic, mesopic, scotopic and dynamic conditions


Keratoconous
Cartesia offers advanced keratometry measurement, providing precise data on corneal curvature. It captures detailed front surface readings, enhancing diagnostic accuracy for ectatic conditions like keratoconus. This feature supports effective surgical treatment planning for corneal procedures
Scheimpflug
A Scheimpflug camera uses the Scheimpflug principle to capture detailed images of the cornea and anterior chamber, enabling measurements like central corneal thickness and anterior chamber depth
