New Year's resolution: new electrodes and devices

Our very best wishes for 2020. The new year begins with the good news that Okuvision is ready to deliver.

Before Christmas, however, it transpired that the CE certification of our products would take more time. It is now clear that it will be slightly longer than we were able to foresee in before the holidays.

To fulfill all regualtory requirements in the quickest way possible, we are in close exchange with the Notified Body in clarification of the outstanding questions. We will keep you informed about the progress.

In the past year we have done what we could in order to avoid any bigger supply shortages and we would like to thank our partners and users once again for their understanding and patience. Alas, it might now, be unvoidable that some therapy users run out of electrodes.

The shipment of new electrodes and devices will definitely resume immediately after issue of the CE mark. We deeply regret that we have to aks you for a little more patience.

We wish you a happy and prosperous 2020 abd look forward to hearing from you.

A joyous festive season and a prosperous new year

Okuvision GmbH is looking back on an exciting year of reformation and rebuilding. We are glad to be able to say that we have reached all the goals we could influence the outcomes of. Unfortunately, however, the CE certification could not be concluded before the end of the year .

The majority of our clinical and distribution partners are now officially back and we look forward to 2019 with anticipation.

Over the last few months we had the opportunity to talk to many existing and prospective users of our TES-therapy, which gave us deep insight into their individual needs and requirements. This will have a significant impact on our work in the future.

We would like to take this opportunity to thank all our active therapy users, people interested in the therapy as well as our partners at the Competence Centres and Opticians for your trust and patience.

We wish you all a joyous festive season and a happy and prosperous new year.

03.06.2019 | Okuvision GmbH relaunches

Supply of transcorneal electrical stimulation (TES) is ensured

Following the announcement in March that with the liquidation of RETINA IMPLANT AG the supply of the OkuStim® therapy system for transcorneal electrostimulation (TES) will also be discontinued, patients and active users, as well as many clinics, ophthalmologists, and some patient associations, have reacted disappointed and sometimes emotionally. It became very clear that due to the lack of alternative treatment options and sources of supply there is a recognisable demand for the OkuStim® therapy system.

This intense response has resulted in an intensive discussion among the team and their supporters how the supply of the Okustim® therapy system can be ensured. We are very pleased that there is now a concrete answer to this question:

Formerly an independent company and integrated into RETINA IMPLANT AG in spring 2017, OKUVISION GmbH is currently being relaunched. With the help of an investor, OKUVISION GmbH will ensure the supply of the OkuStim® therapy system and consumables. We plan to have the production reopened and validated at a new location, by October, to facilitate a successful audit and new CE-certification. Former members of RETINA IMPLANT staff have been won for the new task at OKUVISION GmbH and our team is ready for the new beginning.

Most importantly: thanks to the extraordinary commitment of our production team, it has been possible to produce such a large quantity of electrodes in the recent weeks that the supply of active users should be secured for the coming half-year.

This provides us with the time necessary to rebuild OKUVISION GmbH. We expect to require about 6 months until we have everything up and running and can also offer the OkuStim® system to new users.

We are very excited and grateful for this opportunity, especially in regard to the many people affected by retinitis pigmentosa and the fact that transcorneal electrostimulation is one of the few, if not the only, meaningful therapeutic approach available to people affected by RP today and for the foreseeable future.
