Conditions Treated

    Our Restore Vision Clinic offers the exclusive Fedorov Restoration Therapy. We combine the sciences of ophthalmology and neurology to restore vision loss from optic nerve damage and retinitis pigmentosa. 

    Principles of Fedorov Restoration Therapy

    Our long-term experience in the treatment and care of visually impaired patients and knowledge in the development of medical approaches allows us to establish the principles to which Fedorov Therapy corresponds:

    More than 20 years of experience

    Ours is a proprietary electrical stimulation therapy and we have practiced the treatment of visual impairments for more than 20 years.


    Our goal is to achieve the best possible results

    Through our deep comprehension of the vision restoration treatment and continuous contact with our patients, we strive to attain exceptional results.


    Treatments are tailored to individual needs

    Fedorov Therapy is performed by us, neurologists, so that each treatment session is optimized.


    Personalized Care Plan

    We offer a personalised care plan with specific attainable objectives, to provide each patient with the care they require to achieve treatment goals.


    Extensive Knowledge and Expertise

    Our clinic was established to improve and maximize the eyesight and quality of life of our vision impaired patients, through our dedication, knowledge and expertise.

    Being the authors of this treatment, we ensure the Fedorov Electrical Stimulation Therapy is used in our clinic.

    Fedorov Restoration Therapy

    The application of electrical stimulation therapy (repetitive transorbital alternating current stimulation) is based on the potential of the vision system to adapt to functional and structural changes that can be induced by external influence. For example, by using electrical current impulses. Clinical experience has shown that, if such activation is performed for several weeks, it can cause significant changes (induced plasticity of visual system) in the functional state (activation) of the entire brain-vision system.

    In cases of vision deterioration caused by optic nerve and retinal diseases, such as plasticity of the vision system, intervention is strongly needed to restore vision. By decreasing the defects of visual fields or causing the enlargement of preserved areas of vision and increasing vision sharpness, we can promote a normal quality of vision. Such results can be achieved through therapeutic electrical stimulation that activates the retinal ganglion cells, improves the signal conductivity through visual pathways (including the optic nerve), and embodies the visual cortex reserves, resulting in an optimal, functional state of the whole brain and improving the vision system. Treatment by properly adjusted impulses (electric current therapy) focuses on non-invasive electrical activation of retinal neurons using impulses with different shapes and ranges through electrodes located around the eyes (periorbitally).

    Retinal neurons have an important role in the working of the visual system. On one side of the brain, they get information using extensions, called axons, through the optic nerve, sending this information to the rest of the brain. On the other side, ganglion cells get signals from receptors (cones and rods), coding information on the environment.

    From a practical point of view, the use of therapeutic electrical stimulation means picking optimal impulses that can create artificial visual effects such flickers, flashes or more complex light effects in the patients, thanks to the effect on retinal ganglion cells. Their existence is the result of the activation of cortical visual centers found in occipital lobes of both hemispheres. External electrical signals applied to the retina can cause functional activity in the visual cortex (prestriate area) located deep in the brain.

    Activated neurons of visual centers can better analyze information received from the retina, which was reduced by optic nerve damage causing a weakening activating effect on ganglion cells. In turn, this creates conditions for vision improvement. Similarly, the photo camera matrix extends the diaphragm in low-light situations.

    During the treatment process, the conduction visual pathways (optic nerves, tracts and central visual pathway) are activated both from the periphery by retinal ganglion cells and from the top by the neurons of the occipital cortex. The method of therapeutic electrical stimulation was developed by realizing that such organization of the visual system includes the interaction of center and periphery, cells and their axons, and forming a new connectivity between different parts of the brain.

    Success of the treatment results is mainly because of the therapeutic electrical stimulation that creates plastic changes in the vision system. These changes mainly occur in the visual cortex, given that the functional abilities and plasticity of neurons of the visual cortex are much higher than that of lesioned, optic-nerve fibers or even damaged retinal neurons (first of all ganglion cells). This activates the vision centers, allowing for significant improvement of visual processing to happen. These results, combined with the activation of retinal ganglion cells, is the basis of getting the stable effects of partially or permanently restored vision.

    Patients who have undergone a course of Fedorov Therapy are divided into two groups, according to their vision improvement:

    1. Responders – patients with positive dynamics in vision functions. This group includes no less than 60% of patients.
    2. Non-responders – patients in whom no or practically unremarkable vision improvement was found eight weeks after stimulation.

    In the responder group, the positive dynamics of vision functions are evaluated quantitatively. The significance of how patients improve vision (degree of visual acuity, increase and extension of visual fields or decrease of their defects) influences the improvement of a patient’s quality of life. Done in 2011, the study has revealed that therapeutic electrical stimulation causes vision restoration after unilateral, long-term, optic-nerve lesion, as evaluated both by VF (improved detection ability) changes and improvements in some National Eye Institute Visual Function Questionnaire subscales. Both were positively but low correlated, which suggests that factors other than visual-field size also contribute to improved, vision-related quality of life.

    Vision Improvements With Fedorov Therapy Are Stable?

    As a rule, vision improvement is stable and, for 75% of responders, is preserved for up to several years. In part, a patient’s visual health can return partially or completely to a baseline level. This is seen when the optic-nerve disease or retina damage progresses (for example, glaucoma with unstable intraocular pressure or new attacks of multiple sclerosis), although any stress can also have a negative effect on positive treatment results.

    Repeated Treatment Courses Improve Vision More Significantly

    Repeat courses are needed to achieve the full effect of stabilization or significant vision improvement. Also, it has been shown that, in cases of significant and severe optic-nerve pathology, positive dynamics progress gradually and only several treatment courses can provide a notable treatment effect.

    Limited Undesired Effects or Side Effects

    Normally, (for more than 90% of patients), the sessions of electrical stimulations are tolerated well and without any notable, undesired effects or painful sensations. For highly sensitive people, some types of skin reactions, such as moderate tingling, are felt, but remain tolerable.

    Some undesired effects like tiredness, weakness, a short-lived headache, and sleep disturbances have been observed, but rarely do they require any treatment. Our approach is physiological and friendly to the brain. As with any therapy, close attention is paid to how an individual patient tolerates the course of treatment, and necessary adjustments in the therapy are made, as needed. Side effects of therapeutic electrical stimulation may result when a patient has existing contraindications. If such contraindications are excluded, there is no risk of adverse effects on vision or any other functions.

    About Fedorov Restore Vision Clinic

    Since 1995 we have been not only developing methods for vision recovery, but also treating patients with optic nerve atrophy and those patients with abnormal retina and vision impairment attributed to brain disorders.
