About the service
Device-based treatment is an individual programme of visual exercises for amblyopia and selected binocular vision problems. It forms part of care alongside necessary optical correction and other prescribed treatment.
Who the service is for
Strabismus
Patients who need work on binocular interaction, fusion and the sensory component of strabismus before or after other treatment stages.
Convergence insufficiency
Patients with confirmed weak near convergence and related symptoms.
Fusion disorders
When fusional reserves are reduced or binocular fusion is unstable on testing.
Accommodative dysfunction
When focusing dysfunction and visual fatigue are confirmed and functional training is prescribed.
How results are assessed
Assess response using specific baseline and follow-up visual-function measures, not only a subjective impression.
Assessment before choosing treatment
Start a course only after ophthalmic diagnosis and prescription. Do not increase exercise duration or intensity independently.
Progressive myopia
Device exercises may address accompanying accommodation, but a separate myopia-control plan is required.
After strabismus treatment
Orthoptic and diploptic exercises may be used in selected patients to develop binocular function after optical or surgical treatment.
Myopia progression control
In progressive myopia, device exercises must not replace evidence-based myopia-control strategies and axial-length monitoring.
Astigmatism
Device-based treatment does not guarantee 100% vision and does not remove the optical/anatomical refractive cause of myopia, astigmatism or hyperopia.
Amblyopia treatment
In amblyopia, device methods should not automatically be presented as substitutes for glasses, patching or atropine; treatment depends on cause and response.
Strabismus and eye alignment
In strabismus, device-based exercises cannot mechanically correct the angle of eye deviation; some patients need a surgical stage.
Reduced vision
Acute pain, sudden vision loss, new persistent diplopia, flashes or a curtain-like shadow require diagnostic assessment rather than a scheduled training session.
Results and documents
Bring previous reports, spectacle prescriptions and prior treatment records if available.
Do not change medicines yourself
Bring the child’s current glasses. Do not stop prescribed optical correction unless instructed.
Assessment before treatment
Report new diplopia, sudden vision loss , pain, flashes or other acute symptoms because these require diagnostic assessment rather than routine training.
Limitations and safety
In progressive myopia, device exercises must not replace evidence-based myopia-control strategies and axial-length monitoring.

Stages
Stage 1
Diagnostic assessment
Visual acuity, refraction and ocular health; binocular and ocular-motor testing when relevant.
Stage 2
Define the functional target
The clinician identifies the specific function to train: amblyopic eye, convergence, fusion, binocular function or accommodation.
Stage 3
Select the method
One or more procedures are selected from the pleoptic/orthoptic list.
Stage 4
Treatment session
The patient performs exercises under specialist supervision using the prescribed settings.
Stage 5
Course and monitoring
Tolerance and response are monitored and the program may be adjusted.
Stage 6
Control examination
Target measures are compared with baseline and the next treatment step is determined.
Service benefits
Training selected functions
Exercises are selected for specific visual function problems identified during examination.
A focus on a specific goal
The course is prescribed according to the diagnosis and treatment goals, rather than using one programme for every vision complaint.
No surgical intervention
Device-based sessions do not require eye incisions; the doctor determines suitability and the course schedule.
Monitoring changes in vision
Repeat measurements allow progress to be assessed and the plan adjusted using objective findings.

Device-Based Vision Therapy at KazRIED
Device-based vision therapy consists of pleoptic, orthoptic, and functional exercises prescribed by an ophthalmologist for a specific purpose:
- treating amblyopia;
- addressing binocular vision disorders;
- training convergence and fusional reserves;
- training accommodative function.
The methods are selected after a diagnostic assessment. They do not replace glasses, standard amblyopia treatment, myopia control, or strabismus surgery when these are indicated.
How does device-based vision therapy differ from other services?
From diagnostic testing: the patient completes a course of targeted exercises rather than simply receiving measurement results.
From physiotherapy: the service focuses on visual, binocular, accommodative, and pleoptic exercises.
From strabismus surgery: the exercises train visual functions and sensory cooperation between the two eyes, but do not mechanically change the position of the eye.
Additional advice and situations
Refractive measurement
Control visual acuity and refraction.
Binocular-vision assessment
Repeat binocular, convergence and fusional-reserve testing if these were treatment targets.
Amblyopia treatment
For amblyopia, decide whether to continue or modify optical correction, patching, pharmacologic or digital treatment.
In strabismus
For strabismus, assess the need for further orthoptics, observation or surgery.
Myopia progression control
For progressive myopia, separately monitor refraction and axial length and discuss a myopia-control strategy.
How is device-based vision therapy selected at KazRIED?
Device-based vision therapy at KazRIED is not a single universal procedure, but a range of pleoptic and orthoptic exercises with different goals.
The starting point is therefore a diagnostic assessment and a treatment prescription from an ophthalmologist.
The clinician determines whether training should target the amblyopic eye, binocular fusion, convergence, fusional reserves, or accommodation. A specific method is then selected, and the outcome is assessed using the relevant measures.

Frequently asked questions
What is pleoptic and orthoptic treatment?
It is a clinician-prescribed program of exercises and device-based techniques targeting specific visual functions, such as the amblyopic eye, binocular interaction, convergence, fusional reserves or accommodation.
Can pleoptic or orthoptic treatment restore 100% vision?
A 100% restoration of vision cannot be guaranteed. Outcome depends on the diagnosis, age, baseline visual function, appropriate optical correction and adherence to the prescribed program.
Can device-based treatment eliminate myopia?
No. These exercises do not eliminate the anatomical refractive basis of myopia and do not replace glasses or contact lenses. Selected exercises may be used for associated accommodative or binocular disorders.
Does device-based therapy stop myopia progression?
Device-based exercises alone are not considered an evidence-based method for controlling axial eye growth. Progressive myopia requires a dedicated myopia-control strategy and appropriate follow-up.
Why is pleoptic treatment used in amblyopia?
Amblyopia treatment aims to improve function of the weaker eye and visual processing. Device-based and digital approaches may form part of a broader treatment plan together with appropriate optical correction and other prescribed therapies.
Can device-based treatment replace patching?
Not always. Patching or atropine penalization may be prescribed for amblyopia after refractive correction. Device-based or digital treatments are selected individually and should not replace prescribed therapy without clinical review.
What can orthoptic treatment do for strabismus?
Orthoptic and diploptic exercises may train binocular interaction, fusion and fusional reserves. They cannot mechanically correct every ocular deviation.
Can strabismus still require surgery?
Yes. The need for surgery depends on the type and magnitude of deviation, its cause, age, refractive error, amblyopia and binocular function. Surgery and orthoptic treatment address different aspects of strabismus.
What is convergence training?
It consists of exercises designed to improve coordinated inward movement of the eyes during near work. It may be prescribed, for example, for confirmed convergence insufficiency.
What are fusional reserves?
They represent the visual system’s reserve for maintaining a single image when the demand on binocular alignment changes. They can be measured and trained when clinically appropriate.
