An excellent choice for accurate IOL calculations for every patient

The Lenstar 900 APS provides highly accurate laser optic measurements for every section of the eye −from the cornea to the retina− and is the first optical biometer on the market that can measure the thickness of the crystalline lens. With its integrated Hill-RBF Method, Barrett and Olsen formula and the optional Toric Planner featuring the Barrett Toric Calculator, Lenstar 900 APS provides the user with latest technology in IOL prediction for any patient.

  • Match the axis

Lenstar features dual-zone keratometry or T-Cone topography for
precise astigmatism and axis measurement

Lenstar features dual-zone keratometry or T-Cone topography for precise astigmatism and axis measurement

  • Best Toric Results
    • Lenstar features dual-zone keratometry or T-Cone topography for precise astigmatism and axis measurement.
  • Improved outcomes with dual zone keratometry
    • Measurement equivalent to the “Gold Standard”
    • Spaced 32 measurement point pattern improves precision
  • Topography for torics – match the axis
    • With the optional T-Cone toric platform, the axis and astigmatism measurement of Lenstar is extended with true 11-ring Placido topography. This additional data improves the efficacy and safety of toric IOL surgery, eliminating the risk of irregularities and allowing the user to double check the axis location.

"We utilize the Konan specular microscope after all of our DSAEK surgery. The information that the specular microscope provides is valuable for assessing the long term effects of the surgical trauma of the procedure, and specular microscopy is critical to understanding your personal outcomes with DSAEK." - Dr. Terry

Dr. Coble

"The Konan Specular Microscope is very tech friendly. It is easy to use and the information is outstanding. Managing corneal dystrophies and predicting outcomes, such as when to perform a DSEK procedure, has been very advantageous in the care of my patients. The ability to explain subtle visual acuity decrease has helped reduce patient anxiety. The Specular Microscope is well worth the money." - Dr. Coble
