Faster, Easier Endothelial Imaging

CellChek 20 is Konan Medical’s new, non-contact specular microscope that can capture and analyze bilateral exams with one touch in under 40 seconds¹.

The new easy-to-use “Simple Mode” enables one-touch, fully-automated endothelial image capture with analysis, reporting, and exporting of data.

Blazing Fast

The new, easy-to-use “Simple Mode” enables one-touch, fully-automated endothelial image capture with analysis, reporting, and exporting of data.

The completely reimagined CellChek 20 is noticeably improved and simplified; remove the device from the box, connect to power, turn it on, and start imaging.

Konan’s gold standard Center Method™ and Flex Center Method™ are now fully-automated. Automated Center Method displays cell center counted densities and morphometric indices of both eyes immediately after images are captured - all in under 40 seconds.

Key New Features

With CellChek 20 you can capture, analyze and print/export a bilateral exam with just one touch. The new, easy-to-use “Simple Mode” makes running a bilateral exam faster and easier than ever before. CellChek 20 reduces testing time significantly, allowing you to test patients quickly and efficiently.


one-touch imaging

Fast, one-touch imaging of both eyes including positioning, alignment, imaging capture, analysis and print-out/exporting data. 

Optimized Touch Functions

Easy touch-friendly interface makes capturing, analysis, and reporting fast and efficient. Also features pinch-to-zoom image adjustment. 

Automated Trends Analysis

Konan exclusive image location enables relevant visit-to-visit trend analysis to track patient progression. 

25% Higher Resolution

Improved resolution allows better visualization of single cells and cell walls. Superb cell border tracing and gutta exclusion. 

Auto-Capture/Retry

This improved technology allows for successful imaging of difficult or challenging cases.  

> 30% Larger Image Area

The field of view has been increased to 0.25mm x  0.55mm, enabling better corneal visualization and more cells to be analyzed.

Flexible Touch Screen

The flexible 10.6” wide touch screen can be turned and tilted 180°, providing better ergonomics, space savings, and flexibility with technician use from any of the four sides: front, back, left, and right.

 

Fully-Automated Analysis

CellChek 20 offers fully-automated: Center Method; Flex-Center Method; and Auto-Trace analysis. These analysis methods provide one-touch, high precision results FAST.   

These fully-automated analysis methods are offered alongside the traditional manual Center and Flex-Center analysis methods, offering a total of 6 analysis options.   

Konan’s Center Method is mentioned in FDA panel minutes as being the “gold standard”, and is used by virtually every professional reading center.

New Auto Center Method
With the new Auto Center Method, the center of each individual, visible cell is automatically marked. Guttae and other dark regions are automatically excluded.

New Auto Flex-Center Method
The new Auto Flex-Center Method is an additional automated tool for analyzing images of advanced stage diseased corneas in which only a very few cells are visible.

Clinical Benefits


Cataract Surgery and Premium IOLs

Low endothelial cell counts and pre-existing dystrophies can markedly reduce the potential for positive surgical outcomes from an otherwise uneventful cataract surgery. Surgeons are finding these data points critical when recommending premium IOLs: verify and document pre-operatively that the cornea is not suspect to more likely post-op complications difficult to explain with the investment in premium IOLs.


Refractive Surgery

There are various reports in the literature of refractive surgery complications with corneas that have pre-existing dystrophies. It is incumbent on refractive surgeons and referring Optometrists to carefully assess the corneal health prior to performing or recommending an elective corneal surgery to enhance the potential for positive surgical outcomes.


General Corneal Health Assessment

Konan specular microscopy is an invaluable tool to screen for corneal diseases as such as Fuchs’ Dystrophy, keratoconus, other corneal dystrophies, and trauma. You won’t believe what you’ve been missing.


Contact Lenses

In the never ending battle to minimize the oxygen barrier from contact lens materials and lens hygiene, specular microscopy provides a highly detailed view of the integrity and distress of the cornea from the endothelium. As the “canary in the coal mine”, the endothelium can be an invaluable indicator of corneal distress.

*Konan specular microscopes are recognized in the industry as the de facto standard for ECD determination. This is supported in the minutes from the FDA panel meeting to discuss the ARTISAN® lens: “Data from 12 sites were chosen because they used the Konan specular microscopes. This instrument is now the accepted standard for the most accurate determination of endothelial cell density."
