Optical Coherence Tomography (OCT)

Nepal Eye Hospital offers comprehensive Optical Coherence Tomography (OCT) services using advanced imaging systems from Heidelberg Engineering, Germany. With both ANTERION® (Anterior Segment OCT) and SPECTRALIS® (Posterior Segment OCT), we provide complete, high-precision imaging of the eye—from cornea to retina.

These technologies support early diagnosis, accurate surgical planning, disease monitoring, and improved treatment outcomes across a wide range of ocular conditions.

Our OCT Technology Platforms

1. ANTERION® – Anterior Segment OCT

(Heidelberg Engineering, Germany)

ANTERION® is a swept-source anterior segment OCT system designed for detailed imaging of the cornea, anterior chamber, and crystalline lens, combined with advanced optical biometry and corneal tomography.

Key Advantages

  • Swept-source OCT with 1300 nm laser
    Faster scanning, deeper penetration, and superior image quality, even in eyes with corneal opacity or dense cataract.

  • Multimodal, all-in-one platform
    Integrates anterior segment OCT, corneal topography/tomography, and optical biometry in a single device.

  • Non-contact and patient-friendly
    Quick scans without touching the eye, ensuring comfort and safety.

  • Highly accurate and reproducible measurements
    Essential for precise surgical planning and consistent follow-up.

Clinical Applications of ANTERION®

Cornea Module

  • Corneal topography and tomography

  • Pachymetry mapping (corneal thickness)

  • Anterior and posterior corneal surface analysis

  • Early detection and monitoring of keratoconus

  • Pre- and post-refractive surgery assessment

Cataract & Lens Module

  • High-resolution optical biometry, including:

    • Axial length

    • Anterior chamber depth

    • Lens thickness

  • Accurate Intraocular Lens (IOL) power calculation

  • Crucial for safe and predictable cataract surgery planning

Glaucoma Module

  • Detailed anterior chamber angle assessment

  • Identification of angle-closure risk

  • Supports glaucoma diagnosis and management planning

Anterior Segment Imaging

  • High-resolution visualization of:

    • Cornea

    • Iris

    • Anterior chamber

    • Crystalline lens

  • Useful for corneal diseases, anterior segment disorders, trauma evaluation, and post-surgical follow-up

2. SPECTRALIS® – Posterior Segment OCT

(Heidelberg Engineering, Germany)

SPECTRALIS® is a gold-standard spectral-domain OCT system for detailed imaging of the retina and optic nerve, widely trusted for diagnosing and monitoring retinal and optic nerve diseases.

Key Advantages

  • Ultra-high-resolution spectral-domain OCT
    Enables detailed visualization of individual retinal layers.

  • TruTrack™ Active Eye Tracking
    Minimizes motion artifacts and allows precise follow-up scans over time.

  • Highly reproducible and reliable measurements
    Ideal for monitoring disease progression and treatment response.

  • Multimodal imaging capability
    Supports OCT combined with fundus imaging, autofluorescence, and angiography (where applicable).

Clinical Applications of SPECTRALIS®

Retina Services

  • Detailed retinal layer analysis

  • Diagnosis and monitoring of:

    • Diabetic retinopathy

    • Age-related macular degeneration (AMD)

    • Macular edema

    • Retinal vein occlusion

    • Macular hole and epiretinal membrane

Macular Evaluation

  • Central macular thickness measurement

  • Foveal structure assessment

  • Monitoring response to anti-VEGF injections, laser, and other treatments

Optic Nerve & Glaucoma Assessment

  • Retinal nerve fiber layer (RNFL) analysis

  • Optic disc and ganglion cell evaluation

  • Early detection and long-term monitoring of glaucoma
