User Group for Laser Interference Biometry
ULIB is intended to serve as a platform to exchange information, news, ideas, results, FAQs etc related to optical biometry and its clinical applications.The group is open to everyone sharing the same background and interests. One of ULIB's special concerns is the optimization of lens constants for the calculation of intraocular implant lenses. Due to the fact that - out of a number of reasons - an optically measured axial length is different from the measurement result obtained with ultrasound, IOL constants like e.g. the A constant or ACD constant etc. will in general fail to give good results when used in optical biometry. Therefore, an individual optimization for a given intraocular lens type is necessary. This can be done on the basis of pre- and postop clinical data. A spreadsheet form in MS Excel format which can be downloaded from this site has been designed to accept this data. The results obtained from processing this data are published thus providing maximum benefit to all ULIB members.
