negative Dysphotopsie

A-07: Selective surface modification of intraocular lenses by means of ultrashort-pulsed laser radiation to reduce reflections

Project objective(s)

At the heart of the project is the idea of developing an IOL that can safely prevent the occurrence of negative dysphotopsia (ND).

ND is a post-surgery complication that occurs in up to 15% of patients following implantation of modern foldable lenses, e.g. in the treatment of cataracts. Patients with this complication complain of an irritating, blinder-like restriction of the visual field which is most likely caused by shadows. These shadows are attributed to edge glare phenomena.
