CORNEAL TOPOGRAPHER

Model Name :Cartesia

Model Number: PT-1

Topography Module

Provides precise analysis of the anterior corneal curvature and concentricity

Performs comprehensive imaging and delivers data by utilizing Placido based videokeratoscopy with Scheimpflug tomography

Topography maps and indices

Multiple maps for accurate diagnosi

Acquisition and image processing

Smooth focus assistant system with Auto shot option enables non-touch capture as soon as focus is achieved.

Advanced deep learning algorithms for image processing and it enhances accuracy of resultant topography maps; along with crucial pre-operative parameters while planning for refractive or cataract surgery.

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

Topography Report

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

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
