CellChek® D | D+

Eye Bank Specular Microscopes

Designed to improve patient outcomes, CellChek D+ redefined specular microscopy in Eyebanking.

It was quickly and widely adopted by many of the world’s finest Eye Banks.

Clinical Applications

Donor cornea tissue assessment

Clinical Benefits

Provides remarkable views of endothelium, intra-stomal structure and the epithelium

For the first time, visualize blood cells, fungus, rough keratome cuts, dead cells, and epithelial anomalies

CellChek D+

Introducing the first multi-imaging system for donor corneal analysis.  CellChek D+ provides an amazing view into the cornea that simply has never been seen before defining the structure of the endothelium, stroma and epithelium. Comprehensive imaging to assist both eye banks and corneal surgeons to make better decisions on implantable material.

New "Donor Enhanced" Imaging System

CellChek D+ features a patent applied for “Donor Enhance” imaging system that provides remarkable views of endothelium, intra-stomal structure, and the epithelium.  The range of new information from which to make better clinical decisions is spectacular (pun intended):  blood cells, fungus, rough keratome cuts, dead cells, epithelial anomalies. Never have we had this view of pre-implanted material.  Corneal surgeons are finding this information to be illuminating in helping to understand graft success and failure.

Broad overview but with large multi-sample analytic areas 

CellChek D and D+ feature a new finder feature with digital measuring / documenting tools.

Patented Cellular Analysis Methods

All Konan specular microscopes feature the Center Method of analysis. Center Method is mentioned in FDA panel minutes as being the “gold standard” and is used by virtually every professional reading center for independent assessment of corneal endothelial analytics.¹ Unlike full-auto assessments, the Center Method provides high precision and repeatability for specular images in which relatively small continuous areas of visible cells are visible.

The Flex-Center method is the third tool for advanced stage diseased corneas in which only a very few number of cells are visible. With this semi-automated, perimeter-count method, again, high precision and repeatability is achieved.  Only Konan provides the rich set of analytic tools for reliable assessment of the entire spectrum of corneal conditions.

It is not surprising that Konan is the global gold standard in corneal endothelial assessment.

Full Graft Imaging

CellChek D and D+ provide a total picture of the cornea.  Use digital measurement tools to identify, measure and document cornea dimensions, defects, and scars.
