Editor’s note: The first of these two studies is a database study from the UK [1]. In it, the authors retrospectively calculated the prediction errors for 2129 first-eye cataract surgeries, in order to recalculate the outcomes for the second eye based on a 50% correction factor. Their main conclusion was to confirm that refractive outcomes for second eyes can be improved by taking into account 50% of the first-eye prediction error when this is within ±1.50 diopters.
