You may be reading this wondering why you should consider the purchase of a specular microscope; we’ll offer two great reasons: 1). It reimburses quite well. 2). Corneal dystrophies are far more prevalent than glaucoma in patients over 40 (Konan citation). Specular microscopy has gained traction in the recent decade due to the advancement in technology and imaging of endothelial cells with such detail and powerful algorithms that data can be quite useful. Changes in endothelial cell morphology, including cell loss, are a strong indication that the cornea is under stress. This is critical information for all patients who undergo corneal surgery such as LASIK, PRK, DSAEK, corneal inlays, intraocular lenses, phakic IOLs, and various keratoconus treatments. On that reason alone it would seem to have a necessary home in those seeking to take diagnostics in Optometry to the next level. Given the strong and consistent reimbursement amounts that Specular Microscopy has offered, many manufacturers have followed suit- launching their own microscope rivaling the Konan (gold-standard) system. We do however favor the Konan for its level of detail, advanced algorithms, and complex software that keeps Specular Microscopy as a “stationed investment” rather than just a space on the pretest table. We so often criticize manufactures whom create systems with external monitors/computers, however we aren’t bothered taking up further space with something so complex in design and innovation.
OUR TAKE: A worth investment of funds and real estate (room).
Konan’s specular microscopes are regularly used for both well vision and medical patients.Corneal dystrophies are far more prevalent than glaucoma in patients over 40.*
The FDA requires specular microscopy as a primary end point for clinical studies for ophthalmic drugs and devices. Konan microscopes are recognized by eye care practitioners, regulatory groups, professional reading centers, and clinical trial experts as the gold standard for endothelial cell analysis. Changes in endothelial cell morphology, including cell loss, are a strong indication that the cornea is under stress. This is critical information for all patients who undergo corneal surgery such as LASIK, PRK, DSAEK, corneal inlays, intraocular lenses, phakic IOLs, and various keratoconus treatments.
Patient complaints including fluctuating vision, blurry vision, foreign body sensation, photophobia, contact lens intolerance, and haloes around lights can be indications of endothelial problems. Patients at risk for these problems include those who have diabetes, glaucoma, retinal disease, or recurrent iritis; those who use long term medications, have had prior anterior segment surgeries, or are long term contact lens wearers.
The new CellChek XL specular microscope represents the latest in endothelial cell analysis algorithms and computer technology.
The instrument is simple to use and provides practitioners with essential information for procedures including DSAEK, corneal transplants, refractive IOLs, contact lens fitting and many others. The testing, from imaging to completion of automated analysis, fits easily into your patient flow. The broad range of patients who need this diagnostic modality also make it a wise economic decision.
The CellChek XL’s side-by-side configuration allows you to place it against a wall or in a corner to minimize space requirements.
The equipment can further add value by providing data for case reports to journals, and allows you to monitor cell changes related to the use of new techniques.
Over 200 peer-reviewed studies and articles attest to the accuracy of Konan’s analysis algorithms. All of the normative data for cellular morphology were developed on Konan devices and are only accurate for Konan devices. Featuring auto-focus, auto-alignment, auto-capture, and auto-cell counting, the CellChek XL easily captures consistent, high quality images of the patient’s corneal endothelium using a patented method that identifies the position of the cellular interface.
The CellChek XL software automatically records the location from which the data samples were acquired. One strong value of specular microscopy is to be able to assess and quantify change in the cornea over time. Without location data, trending is simply not accurate or reliable.
The CellChek XL offers five fixation points for image capture at the center and four peripheral sites, allowing a more comprehensive look at the cornea. This is particularly valuable in cases such as DSAEK, ALK, or in the presence of corneal dystrophies.
Using non-contact optical pachymetry, the CellChek XL provides corneal thickness measurements at all five data sample sites. Independent studies have shown this to be as accurate as ultrasound pachymetry with less potential trauma to the cornea.
The CellChek XL offers five fixation points for image capture at the center and four peripheral sites– featuring auto-focus, auto-alignment, auto-capture, and auto-cell counting.
The CellChek does require connection to an included monitor which displays results, and provides on-screen prompts for use. The CellChek XL cannot be used without this monitor.
An integrated database management system allows robust data mining and simplification of links to electronic medical records. We always recommend speaking with your EHR provider to make certain.
Yes. The CellChek performs non-contact Pachymetry at all five data sample sites. Independent studies have shown this to be as accurate as ultrasound pachymetry with less potential trauma to the cornea (Konan Citation).
