Why is quite simple -

standard biomicroscopy does not provide the

critical detail of the earliest signs of endothelial disease

Clinical Indications

Evaluation of abnormal corneal signs or symptoms
Treatment of known ophthalmic diseases
Treatment of known ophthalmic injury
Preoperative assessment of surgical risk

Clinical Signs of Endothelial Disease

Elevated rate of polymegethism
Presence of pleomorphism
Abnormal reductions in endothelial cell density
Appearance, enlargement, or coalescence of guttae

Clinical Applications

Document a disease process
Simplified patient education ("A picture is worth a thousand words")
Aid in planning the treatment of a disease process
Document the delivery of medical treatment
Document the response to medical treatment

Konan Quote

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." R. Doyle Stulting, MD, PhD.
