Users Group for Laser Interference Biometry (ULIB) on the Web at:


The Users Group for Laser Interference Biometry is devoted to the technology behind precision axial length measurements by partial coherence interferometry. Since inception, the ULIB has continuously grown, with a mailing list presently serving 54 colleagues from 16 different countries. You are invited to add your name to this list at any time. This mailing list, as well as the ULIB website, was originated by Dr. Wolfgang Haigis of the University of Würzburg, who continues to oversee its many helpful features.

During the past few years, Dr. Haigis has collected, calculated and/or refined IOL constants of 22 different types of intraocular lenses. Together with additional results for 5 lenses which were supplied by members of the group, this data is published on the optical biometry lens constants of the ULIB website.

The ULIB is interested in obtaining as much data as possible and you are encouraged to participate. The best way to submit data is through and Excel spreadsheet, available from this download area. Your participation will substantially benefit the ULIB database and improve the accumulated statistics for the calculated lens constants.

In the near future, the ULIB web site will include an area from which you can download IOL constants onto a disk. The disk can then be inserted into optical biometers such as the LENSTAR® or IOLMaster® to automatically update IOL constants.
