Optical Biometer

  • Complete optical biometry

    The Colombo Myopia measures up to 8 values, including axial length, keratometry, anterior chamber depth, central corneal thickness, white-to-white, pupil size, retinal thickness, and choroidal thickness (optional).

  • 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.

  • Myopia Progression Analysis

    The Colombo IOL provides trend analysis of important parameters in myopia management, such as axial length, AXL variation, AXL/CR ratio, etc. This analysis guides clinicians in making informed decisions for effective myopia control strategies.

  • Choroidal thickness Analysis (optional)

    Studies have found that choroids are thinner in longer, more myopic young adult eyes[1]. The findings suggest that choroidal thickness should be evaluated in myopia management. The Colombo IOL provides HD OCT images and measurement of SFChT for deep study in choroidal layer in myopic eyes.
