Changing the Course with TES Therapy
A genuine opportunity for those affected to slow visual field loss is transcorneal electrical stimulation (TES) with OkuStim® 2 – the only CE-marked medical device for the treatment of retinitis pigmentosa.
During OkuStim® therapy, weak electrical impulses pass through the cornea into the eye. They spread intraocularly and polarise the retinal signalling pathways. This aims to activate neuroprotective processes that slow the progression of the disease and may prevent or delay later stages of retinitis pigmentosa. The earlier therapy starts, the better.
OkuStim® 2 – simpleapplication in just a fewsteps
OkuStim® is designed so that patients can quickly learn to use it and perform the treatment independently at home. The therapy is applied once a week for 30 minutes. OkuStim® is available by prescription only. Please consult your physician before use and read the complete instructions for use. Below is a brief overview of the procedure:
1
Take the OkuStim® 2 out of its packaging and switch it on. Press the on/off button for at least 2 seconds. Insert the OkuEI® M into the electrode holder of the OkuStim® 2.


2
Take a comfortable and stable sitting position. Put on the OkuStim® 2 device.
