This was magnificent, it was really like live surgery. It is very easy to use, I would definitely promote it.

Per Kjærsgaard-Andersen

Per Kjærsgaard-Andersen
We have worked with ORamaVR and our residents absolutely love training with the platform. This has really been good for our training, we are really encouraged with this technology and I am really trying to interest all my colleagues and training centers that this is neccessary for them to make their residents better.

Lawrence D. Dorr

Lawrence D. Dorr

Very nice experience and it will be very fruitfull for young surgeons. It’s a great tool and helpful for the training.

Lazaros Poultsides
