EDoF lenses allow cataract and refractive-lens-exchange patients to have improved intermediate-distance vision. The lenses are made of different materials that have different chemical and physical properties. Their optical design is also different. We compared them in an optical quality analysis.

Safety in IOL exchange
We set out to study IOL exchange in patients who had IOL complications but otherwise had healthy eyes and we found visual and refractive outcomes were generally good. Changing the lens does not cause a significant change in aberrations. Intra- and postoperative complications were mostly mild and ...

Simulating IOL vision before implanting a lens
IOL simulators, where the patient can experience vision through IOLs prior to IOL implantation, are gaining interest among researchers and clinicians. We examined the correlation between one look-through simulator and the optical properties of modern IOLs, that we measured using an IOL metrology ...
