Endothelial cell morphology is like a ‘canary in the coal mine’…a potential warning that the structural stability of the endothelium has been affected, possibly by surgical procedures, disease, trauma or contact lenses.
Endothelial Cell Counts are Required for ICL Implantation
Your patients deserve the assurance of the collecting the same high quality data to assess and document that the cornea is physiologically adequate to support these surgical interventions.

CL (implantable contact lens) or PIOL (phakic intraocular lens)
- High precision and repeatability
- Excellent visualization of even stage +1 / +2 guttata that could significantly skew results
- Analysis of both cell counts and cell morphology changes (morphology is not assessed with a “card”)
- Changes in morphology can be a very sensitive indicator of corneal stress
- Unique ability to identify endothelial data location and assess trends over time
- Acquiring endothelial cell count or morphology changes over time from dissimilar locations can present erroneous assumptions on trends analysis
- Technician administered diagnostic test with full photographic documentation and statistics in only seconds.
- Does not require additional physician chair time and eliminates the inherent problems of “card” estimates.
- Important complementary uses for pre-operative assessments of corneal and other anterior segment procedures
Premium refractive products require premium attention to eligibility. Konan CellChek provides easy to use yet robust analytics to assure proper patient selection. There is a reason major manufacturers of ICL’s use Konan specular microscopes for collection of FDA safety data. Your patients deserve no less.

Scleral Lenses with High Risk Endothelial Cell Density
Fundamentals of the importance of endothelial cell density to support implantation of phakic IOLs described above, may have parallels in decision making for scleral lens therapies.
Endothelial cell count of less than 800 cells/mm² is where the problems may arise (Sindt 2010a), and endothelial cell counts <1,000 cells/mm² should be handled with extra care and should not be fitted with scleral lenses to avoid edema.
