Comparing Multisert and AutonoMe.
Two different IOL injector systems, the Multisert and the AutonoMe, were used. Implantation was without critical events in 96 of 96 eyes. Mean implantation time was 41.90 ± 7.11 s with the Mult isert and 52.22 + 12.06 s with Autono me.

The eye's reflex action of Accommodation permits us to focus on a near object and then look at a distant object. The accommodation process is impaired in presbyopic patients and may also play a role in the pathophysiology of myopia. The dynamic approach of the DSA method opens the possibility of seeing changes during the accommodation process in parallel with pupil motility.

EDOF IOL research
The use of monochromatic light in the assessment of intraocular lenses (IOLs) has been criticized in the past for not representing the real-world situation. In our in-vitro study, we aimed to measure and compare the image quality of three extended-depth-of-focus (EDOF) IOL models. The EDOF IOLs proved more tolerant to defocus than a standard monofocal IOL.

In cataract surgery small corneal incisions are associated with a significantly better visual recovery. What are initially small incisions can enlarge during surgery and that impedes the positive effects of keeping the incision small. Our goal was to identify the surgical factors that cause a larger final incision size. We can recommend that IOL-manufacturers should reduce the vertical diameter of the injector tip.
