Wobbling PWr

Did you know that ex vivo wobbling pattern looks similar to in vivo one, but for a non-accommodated eye?

We are proud to present the very first results of ex vivo wobbling wobbling/overshooting experiment and simulations!

Investigation of crystalline lens overshooting: ex vivo experiment and optomechanical simulation results Introduction: Crystalline lens overshooting refers to a situation in which the lens momentarily shifts too much from its typical location immediately after stopping the rotational movement of the eye globe. This movement can be observed using an optical technique called Purkinje imaging.Methods: In....

A BREAKTHROUGH!

More news to come...

Do you know that we're hiring again?

Postdoctoral Researcher position is open again:

Postdoctoral Researcher Visual Optics Group at Department of Optics and Photonics, Wrocław University of Science and Technology (vog.pwr.edu.pl) is seeking a Postdoctoral Researcher to work on the basic science project entitled: “Complex analysis of oscillatory inertial movements of the crystalline lens”, funded by Na...

Today we welcomed a new member of the team: Fabian Dębowy.
Fabian works on processing of the wobbling images/sequences registered with use of our setup and significantly strengthens our team in terms of developing the numerical procedures.

Nice to see you in our team, Fabian!

Visual Optics Group is seeking for a Postdoctoral Researcher to be involved in the project:

https://euraxess.ec.europa.eu/jobs/621679

The project is meant to merge multidisciplinary research from the areas of biomedical/mechanical engineering, computer science (modelling tools), physics (classical mechanics) and physiological optics.

If you have a PhD degree in Mechanical Engineering, Biomedical Engineering, Physics or Computer Science and are experienced in finite elements methods (FEM) modelling, just don't wait and apply for a position!

that crystalline lens wobbling was first observed in 1936 by an australian medician A.W. D'ombrain?

He described a clinical case of a cataractous subject, whose lens was "tremulous" while being examined with slit-lamp.

His observation was as follows:
"on the slightest movement of the eyes, the lens trembled as if it were suspended on a elastic ring".

Without physical background of the author, the explanation of the phenomenon was still unknown.

New in the lab:
it's big & heavy.
Now the wobbling research has solid basis for investigations 😉.

Brace yourselves!
Bioethical Committee Approval is coming!
(Well... almost...)
There's still some time left before we start the in vivo measurements, but a huge step to the approval has been made!
Good job !

During yesterday's online lab meeting we discussed on the optical simulations of wobbling in Zemax, bioethical committee approval (in progress) and plans for... "shopping" the equipment and accessories for the purpose of future experiments.

Thanks to Marta Skrok, Agnieszka Boszczyk, Agnieszka Jóźwik, Joanna Przeździecka-Dołyk and Damian Siedlecki for this productive discussion!

Welcome to "Crystalline Lens Wobbling Research Lab"!
It's brand new, still not fully equipped, but for sure it's going to be the best place to do research in physiological optics!
