Moderate to Dense Cataract

Measuring a Moderate to Dense Cataract

In measuring a moderate to dense cataract, the IOL Master axial length display will typically show the above characteristics. Often, the secondary maxima will completely disappear into the baseline. As long as the primary maxima is narrow, and has a centered terminal peak, the measurement is considered valid.

Remember to use the Best Measurement Technique and sample several areas around the center of the measurement reticule until the best display is obtained. The important components of accuracy with the IOL Master are: correct alignment with the fixation light, measurement consistency, and a correct display pattern. Experience has shown that this general rule applies to signal-to-noise ratios as low as 1.6.
