| Feature | Swept-Source OCT | Spectral-Domain OCT |
|---|---|---|
| Light Source | Uses a tunable laser around 1050 nm wavelength for deeper penetration and higher stability. | Uses a broadband super-luminescent diode (~840 nm), limited in depth and more affected by scattering. |
| Imaging Depth | Exceptional penetration through retinal pigment epithelium and into the choroid — visualizing deeper layers clearly. | Limited penetration; choroidal structures often indistinct or lost in shadow. |
| Scanning Speed | Fast data acquisition, enabling quick, high-density scans with reduced motion artifacts. | Slower capture; longer scans often suffer from motion blur and patient discomfort. |
| Image Quality | Consistent high-definition images across tissue layers, even with cataracts. | Excellent for retinal surface imaging but signal quality drops with depth or opaque media. |
| Performance in Media Opacity | Better penetration through cataracts, corneal haze, or vitreous hemorrhage. | More susceptible to scattering; image quality declines significantly in such conditions. |
Dream OCT VG100D is designed for full-eye diagnostics in one workflow—retinal OCT/OCTA plus anterior segment OCT/OCTA. Powered by SuperDepth™ technology, it provides deep imaging depth (9 mm retina / 12.2 mm anterior segment in air), rapid 100 kHz scanning, and widefield coverage (83° single scan with montage up to 175°), enabling efficient clinical imaging and detailed visualization beyond the posterior pole.
