One of ULIB's special concerns is the optimization of lens constants for the calculation of intraocular implant lenses. Due to the fact that, for several reasons, an optically measured axial length is different from the measurement result obtained with ultrasound, IOL constants such as the A constant or ACD constant will generally fail to give good results when used in optical biometry.
