Optical Biometer

  • Complete optical biometry

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

  • IOL Power Calculation

    The IOL power calculation module is 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, which is beneficial for both patients and doctors.
