Optical ophthalmic biometer Colombo™ IOL

tabletop

Measure up to of 8 values Simultaneously imaging of cornea and retina in high definition All-in-one design, no extra PC required Built-in IOL power calculation User-friendly operation Complete optical biometry The Colombo measures up to 8 values, including axial length, corneal curvature radius, anterior chamber depth, central corneal thickness, white-to-white distance, pupil size, retinal thickness, and lens thickness (lens thickness is only available in Colombo IOL II) Visualizable fixation check To obtain reliable axial length values, fixation is important during measurement. Colombo allows you to visually verify your measurement, the alignment can be driven to the center of macula. This helps to increase the repeatability of measurement for those patients with poor visual acuity. 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.
