The TOMEY Casia 2 OCT is a state-of-the-art swept-source anterior segment Optical Coherence Tomography (OCT) system designed and manufactured by TOMEY Corporation, Japan, a world leader in ophthalmic diagnostic technology. This advanced imaging device provides high-resolution, cross-sectional, and three-dimensional images of the anterior segment of the eye, including the cornea, anterior chamber, iris, and crystalline lens. With its non-contact scanning technology and ultra-fast imaging speed, the Casia 2 delivers accurate, detailed images that are essential for the diagnosis and management of various eye conditions such as glaucoma, cataract, and corneal diseases.

Advanced Swept-Source OCT Technology

Unlike traditional time-domain or spectral-domain OCT systems, the Casia 2 uses Swept-Source OCT (SS-OCT) technology operating at a 1310 nm wavelength. This longer wavelength allows for:

• Deeper tissue penetration, enabling visualization of structures behind the iris and lens.
• Faster image acquisition, with speeds up to 50,000 A-scans per second, minimizing motion artifacts.
• High signal stability, even through opaque or cloudy corneas.

This makes the Casia 2 an invaluable tool for both clinical ophthalmology and research applications where speed, depth, and precision are critical.

Comprehensive Anterior Segment Analysis

The Casia 2 performs a complete analysis of the entire anterior segment in a single scan. It automatically measures:

• Corneal curvature and thickness (pachymetry)
• Anterior chamber depth and volume
• Iris and lens position
• Angle width and configuration

These parameters are vital for evaluating glaucoma risk, preoperative cataract planning, corneal refractive surgery, and postoperative outcomes.

3D Imaging and Angle Assessment

With the Casia 2, clinicians can generate three-dimensional reconstructions of the anterior segment, allowing detailed visualization of the iridocorneal angle, corneal layers, and lens structure.
This capability enables:

• Identification of narrow or closed angles in glaucoma patients.
• Visualization of the anterior chamber for IOL (Intraocular Lens) placement assessment.
• Comparison of pre- and post-surgical anterior eye configurations.

The 3D imaging module also supports cross-sectional slicing, giving ophthalmologists flexible tools for custom analysis.

Integrated Analysis Software

The TOMEY Casia 2 Anterior Segment Analysis Suite provides:

• Intuitive graphical user interface with auto-alignment and auto-scan capture.
• Measurement tools for corneal topography, pachymetry, and anterior chamber geometry.
• Comprehensive database for patient management and progression tracking.
• Export options in DICOM, PDF, and JPEG for EHR integration.

This seamless integration simplifies daily workflow in busy eye clinics and research institutions.

Clinical Applications

The TOMEY Casia 2 OCT is used extensively in:

• Glaucoma Diagnosis and Management
  • Detect and classify open-angle or angle-closure glaucoma.
  • Monitor structural changes over time.
• Cataract and Refractive Surgery Planning
  • Measure corneal thickness, curvature, and anterior chamber depth.
  • Evaluate IOL placement and lens position post-surgery.
• Corneal Disease Evaluation
  • Assess keratoconus, corneal scars, and postoperative healing.
  • Perform pachymetry mapping to detect ectasia or thinning.
• Anterior Segment Research
  • Quantitative imaging for clinical studies and surgical innovation.
