Yalkaid (YG-100K) SS-OCT:

Abstract

Swept-source OCT with full-range imaging capability, offering 12mm posterior scan depth and 15mm anterior scan depth with sub-6 micron optical resolution, utilizing 1060nm wavelength technology for improved penetration through cataracts and vitreous opacities

OCT Optical Source

  • Technology: Swept-Source (SS-OCT)
  • Center wavelength: 1060nm
  • Scan speed: 100,000 A-scans/second (100kHz)

Resolution

  • Axial optical resolution: ≤6μm
  • Transverse optical resolution: 10μm

Scan Depth & Range

Posterior Segment:

  • Scan depth: 12mm (vitreous, retina, choroid)
  • Maximum line scan length: 17mm
  • Maximum 3D/OCTA scan: 15mm × 15mm

Anterior Segment:

  • Scan depth: 15mm
  • Maximum line scan length: 24mm

Scanning Parameters

  • Maximum single scan size (posterior): 18mm × 18mm
  • Maximum single scan size (anterior): 15mm × 15mm
  • Maximum resolution (single scan): 1024 × 1024 pixels
  • Refractive adjustment range: -20D to +15D

Line-Scanning Ophthalmoscope (LSO)

  • Methodology: Line-scanning ophthalmoscope
  • LSO wavelength: 850nm
  • LSO field of view (FOV): 40° × 40°
  • Eye tracking speed: 60Hz
  • Minimum pupil diameter: 2.0mm

Software Functions

  • Anterior segment (AS) quantification and panoramic parameters
  • AI-integrated segmentation algorithm for automated retinal thickness and volume measurement in ETDRS representation
  • Full-range imaging without separate anterior/posterior switching
  • Comprehensive quantification and analysis tools

Clinical Advantages

  • Invisible 1060nm light minimizes fixation distractions
  • Enhanced imaging through cataracts and vitreous opacities
  • Superior choroid and sclera visualization compared to 2-3mm depth of spectral-domain OCT
  • Single-device solution for comprehensive anterior and posterior segment imaging
