Welcome

The David J Apple® Laboratory continues the pioneering work of Dr. David Apple which focuses on intraocular lens research and improving cataract surgery techniques.

Two Apple cores

The core of the laboratory is the people who do the research. While David Apple was alive, he called his researchers the Apple Korps. Now one can talk of a New Generation of Auffarth-Apple Korps.

Refining mini-monovision

In a laboratory study, both Acunex Quantum and RayOne EMV are suitable for mini-monovision. ### Happy Christmas from the Apple Lab!

Vivity and PureSee

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 ...
