KEY TAKEAWAY POINTS

Utilizing accurate Lens Constants for specific IOL models and employing an appropriate new generation IOL formula can improve the refractive outcome of a cataract procedure

Manufacturer recommended lens constants, either theoretically calculated or refined with initial clinical data, or independent websites provided clinical lens constants, such as those from ULIB, are starting points for individual surgeons when working with a new IOL model

Personalization of lens constants is a critically important step for individual surgeons to further improve and optimize refractive outcomes and patient satisfaction. A simple suggested protocol is provided in Fig 2

Resources and tools are available to support individual surgeons on lens constant personalization
