The standard set

The ICHOM Standard Set for Cataracts is the result of hard work by a group of leading physicians, measurement experts and patients. It is our recommendation of the outcomes that matter most to patients with cataracts. We urge all providers around the world to start measuring these outcomes to better understand how to improve the lives of their patients.

1 Includes capsular problems, dropped nucleus or lens fragments into vitreous, return to operating theater, endophthalmitis, persistent corneal edema, and other.
