Optical Biometer

  • Complete optical biometry

    The Colombo IOL measures up to 9 values, including axial length, keratometry, anterior chamber depth, lens thickness, central corneal thickness, white-to-white, pupil size, retinal thickness, and choroidal thickness.

  • Automatic real-time fixation check

    Correct fixation is the key to accurate AXL measurement. The Colombo IOL provides automatic real-time fixation check, as a result, incorrect measurements caused by undetected poor fixation will be eliminated automatically to ensure the measurements are consistently repeatable.

  • IOL Power Calculation

    The IOL power calculation module is primarily employed in cataract surgery to select and compute the most suitable IOL power for patients, ensuring optimal postoperative visual outcomes.

  • More information for retina condition

    Although Colombo is not designed for diagnosis of retinal disease, but the high-resolution images can offer a basic screening of macular pathology before cataract surgery, which is beneficial for both patients and doctors.
