Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
monofocal IOLs group
monofocal IOLs group were implantation with Tecnis® ZCB00
Diffractive multifocal IOLs group
Diffractive IOLs are a type of multifocal (bifocal) IOL that are based on the Huygens-Fresnel principle. Specifically, a diffractive IOL has concentric rings in its posterior surface that form 2 primary focal points independent of pupil size. This optical behavior of the IOL can effectively restore far and near vision. However, it can also cause side effects, such as halos and glare and loss of contrast sensitivity.
