ClinConnect Summary

With increasing demands of patients concerning their visual function after cataract surgery, a variety of advanced technology intraocular lenses (IOL) have become available in the last years. Various developments aim at a reduced spectacle independence for patients after cataract or refractive lens surgery.

Novel technology for providing an extended depth of focus (EDOF) has been developed to account for unmet needs of patients. A novel EDOF IOL, the Acrysof IQ Vivity, has two surface transition elements that work simultaneously by stretching and shifting the wavefront to create a continuo...
