Abstract Details


By inventing optical biometry about 20 years ago cataract surgery has changed fundamentally. Today, by establishing the most modern up-to-date internationally available database for IOL constants, “IOLCon” meets nowadays standards and requirements of a WEB based database for intraocular lens specifications and constants and provides essential data for successful cataract surgery. Biometer manufacturers are implementing the open XML interface to integrate IOLCon into their devices.

Haigis´ ULIB (User Group for Laser Interference Biometry) was the first database of its time to set a milestone in providing optimized constants for cataract surgery. From today's perspective, it no longer meets modern requirements. By launching IOLCon in 2017 a modern data base is worldwide available today which is open to all IOL and biometer manufacturers. By its self-explanatory functionality it is providing its users all relevant lens parameters. IOLCon fulfills the requirements of a modern biometry database and established itself as an indispensable tool for cataract surgeons by today.


Since its launch, IOLCon has grown steadily. As of February 2020, IOLCon offers data on approximately 394 IOL models from 27 manufacturers with over 16.000 clinical data and optimizations for 88 IOL models. Thus, by implementing IOLCon a biometry database is now available, which will also meet the future demands of ongoing developing ophthalmo-surgery. Today, IOLCon is a globally available internet-based database which meets all requirements of modern ophthalmic surgery, it can be accessed at
