The advancement of new technologies in intraocular lens (IOL) design and surgical techniques has increased the expectations of patients for exceptional postoperative vision without any refractive correction. The correct measurement of axial length (AL) and corneal power are crucial for the calculation of IOL power and achievement of the desired postoperative refraction.1 Modern optical biometry devices use either partial coherence interferometry (PCI) or optical low coherence reflectometry (OLCR) to measure several variables including AL. In addition they can measure keratometry (K), anterior chamber depth (ACD), lens thickness (LT) and horizontal white-to-white (WTW) corneal diameter using different approaches.2 Moreover, the built-in software in these devices provides more accurate IOL power calculation and multiple choices of IOL formulas.3 The ...
