Pentacam device

Pentacam is an advanced corneal and anterior segment imaging and analysis system based on rotating Scheimpflug camera topography technology and manufactured by Oculus, Germany. This device is widely used in the diagnosis and management of corneal diseases, evaluation before refractive surgeries (e.g. LASIK, LASEK, corneal transplantation), and glaucoma screening.

  • The main function of the Pentacam device

    • Pentacam uses a Scheimpflug camera that rotates 180 degrees to capture multiple images of the cornea and anterior segment of the eye, and then processes the data in 3D with proprietary software.

    1. Corneal Topography

    Precise mapping of the corneal curvature (including K1, K2, astigmatism level).

    Diagnosis of keratoconus (corneal hump) in the early stages.

    Evaluation of corneal asymmetry and surface abnormalities.

    2. Corneal Pachymetry

    Measurement of corneal thickness at various points.

    Assists in the diagnosis of glaucoma (eye pressure) and evaluation prior to LASIK surgery.

    3. Anterior Segment Analysis

    Anterior chamber imaging (anterior chamber depth, anterior chamber angle).

    Intraocular lens (IOL) evaluation before cataract surgery.

    4. Posterior Corneal Surface Evaluation

    Early detection of keratoconus by examining changes in the posterior corneal surface.

    5. Advanced diagnostic indices (e.g. Belin/Ambrósio Enhanced Ectasia Display)

    Advanced algorithms for the detection of subclinical keratoconus.

  • Main uses of Pentacam

    • ✅ Refractive surgeries (LASIK, PRK, SMILE): Preoperative corneal health assessment.
    ✅ Keratoconus diagnosis and follow-up: Monitoring disease progression.
    ✅ Cataract surgery: IOL power calculation.
    ✅ Glaucoma evaluation: Examining the relationship between eye pressure and corneal thickness.
    ✅ Corneal transplantation: Preoperative and postoperative evaluation.

  • Advantages of the Pentacam device over traditional methods

    • 🔹 No eye contact → Reduces risk of infection.
    🔹 Fast scan (about 2 seconds) → Suitable for restless patients.
    🔹 High accuracy in measuring corneal thickness.
    🔹 Ability to image the back surface of the cornea (which was not possible in old methods)
