Accommodative dysfunction
For patients in whom examination identifies a functional focusing problem and the ophthalmologist considers optico-reflex training appropriate.
About the service
Visotronic M3 sessions provide visual training using a programme selected by the ophthalmologist. The need for a course and its results are assessed against the specific functional problem and measured progress.
Who the service is for
Visual fatigue
For discomfort and unstable focus after prolonged near work, once other causes of the symptoms have been excluded.
Children and adolescents with high visual demands
For school pupils and students when an ophthalmologist includes training in an individual programme after checking refraction.
Myopia as a co-diagnosis
Training may be an adjunctive functional component but is not a substitute for an evidence-based myopia-control plan.
Asthenopic symptoms
For fatigue, blur after near tasks or difficulty switching focus from near to distance and back.
Individual training plan
KazRIED determines the number, frequency and duration of sessions.
Assessment before choosing treatment
A universal course of 5, 10 or 15 procedures is not prescribed without an examination.
After optical correction
When glasses or contact lenses are already appropriately prescribed but a trainable functional deficit remains.
Individual treatment choice
Contraindications are determined using the instructions for the specific Vizotronik M3 device used at KazRIED.
Recovery after treatment
A course does not guarantee 100% vision, freedom from glasses or complete recovery.
Myopia progression control
Vizotronik M3 should not be regarded as a stand-alone proven method to stop axial eye growth in progressive myopia.
Accommodation and refraction
Accommodative spasm is not diagnosed from symptoms alone: ophthalmic assessment and accurate refraction are required.
Lens wear schedule
Acute vision loss, flashes, a curtain-like shadow, severe pain, trauma, marked redness or sudden double vision require medical assessment rather than a routine device-based treatment course.
Do not change medicines yourself
Do not stop prescribed correction for myopia, astigmatism or hyperopia because of device sessions.
Symptoms and history
Have an ophthalmic assessment before starting: fatigue or a presumed “accommodative spasm” is not enough to select the device independently.
Results and documents
Bring spectacles, the current prescription and previous test results if available.
Myopia progression control
For a child with progressive myopia, ask the doctor separately about the plan for monitoring refraction and axial eye length.
Limitations and safety
A course does not guarantee 100% vision, freedom from glasses or complete recovery.

Stages
Stage 1
Ophthalmic assessment
The clinician reviews symptoms, refraction and current correction and decides whether functional training is indicated.
Stage 2
Programme selection
The goal is defined: accommodation, visual endurance, vergence or Vizotronik as one component of a broader plan.
Stage 3
Device setup
The specialist selects the mode and sequence of optical exercises.
Stage 4
Training session
The patient performs tasks through the optical lenses and prisms while fixating a target as instructed.
Stage 5
Tolerance check
Staff assess fatigue, discomfort and correct performance.
Stage 6
Outcome review
The clinician compares symptoms and functional measures with baseline and decides whether to stop, continue or change strategy.
Service benefits
Working on accommodation
When indicated, sessions aim to train the eye's focusing system.
Help with functional strain
The course may be used for suitable accommodation problems; it does not replace treatment of progressive myopia.
No surgical intervention
Device-based sessions do not require eye incisions; the doctor determines suitability and the course schedule.
An individual session programme
The duration and combination of exercises are selected according to visual function and tolerance of the workload.

Treatment with the Visotronic M3 device at KazRIED
Visotronic M3 uses optical lenses and prismatic elements to alternate between visual effort and relaxation.
The exercises primarily target accommodation — the eye’s ability to change focus between different distances — and coordinated eye movements during vergence.
What do the sessions involve?
The patient completes a prescribed sequence of exercises under specialist supervision. Depending on the program, the optical demand, direction of divergence, and intervals of activity and rest vary.
This distinguishes Visotronic M3 from passive light stimulation and from Ambliokor, which uses video-based computerized biofeedback.
What results can be expected?
Training may improve certain measures of accommodation and subjective visual comfort. It is important to distinguish these functional effects from claims to “cure myopia.”
Current recommendations for managing progressive myopia primarily emphasize monitoring refraction and axial length, increasing time outdoors, and using specific optical or pharmacological methods when indicated.
A 2026 systematic review describes the evidence for near–far and accommodative training as preliminary and insufficient to confirm sustained myopia control.
When is the method prescribed?
At KazRIED, these sessions form part of pleoptic and orthoptic treatment and are prescribed following an ophthalmic assessment.
The method may be used for certain functional accommodative disorders and visual fatigue, and as an additional component of a treatment program for patients with myopia.
It does not replace glasses, contact lenses, or evidence-based methods for controlling progressive myopia.
Treatment with the Visotronic M3 device at KazRIED
Treatment with the Visotronic M3 device at KazRIED is a controlled form of optical-reflex training of the visual system.
The device uses lenses and prisms to apply a sequence of accommodative and vergence demands. A specialist selects the settings according to the treatment goal.
The method may be useful for certain functional disorders and visual fatigue, but it does not replace refractive correction and should not be presented as a way to “cure” progressive myopia.
The price for one listed service item in KazRIED’s public price list starts at 2,300 ₸.

Frequently asked questions
What is Vizotronik M3?
Vizotronik M3 is an ophthalmic training device that uses sequential optical exercises with lenses and prisms for functional training of accommodation and vergence.
How is Vizotronik different from ordinary eye exercises?
The optical load is generated by the device and the session follows a prescribed program. Ordinary home eye exercises are not equivalent to a specific device-based training program.
What is accommodation?
Accommodation is the eye’s ability to change its optical focus in order to see objects clearly at different distances.
Why is Vizotronik M3 prescribed?
Its main purpose is functional training of accommodation and vergence when appropriate symptoms and confirmed functional abnormalities are present. Suitability is determined after an eye examination.
Can Vizotronik help with visual fatigue?
In selected functional disorders, training may improve visual comfort and some accommodative measures. However, visual fatigue has multiple possible causes and should be assessed first.
Does Vizotronik treat myopia?
No. The device does not eliminate the anatomical basis of refractive myopia and does not replace glasses, contact lenses or other forms of optical correction.
Can Vizotronik stop progressive myopia in a child?
Accommodative training is not considered a stand-alone evidence-based method for controlling axial eye growth. Progressive myopia requires a dedicated myopia-control strategy and appropriate follow-up.
Should glasses be worn during the course?
Prescribed optical correction should not be stopped independently. Whether glasses are worn during a particular exercise depends on the treatment program.
Can Vizotronik replace glasses or contact lenses?
No. If refractive error requires correction, device-based training does not eliminate the need for prescribed glasses or contact lenses.
Can Vizotronik be combined with Ambliocor?
In selected cases, different device-based methods may be included in the same treatment program, but they address different goals. The ophthalmologist determines whether and how they should be combined.
