    Cost inhibits adoption of SS-OCT

    Cost is likely the primary reason swept-source OCT, a technology with a lot of advantages, has not been as quickly adopted as spectral domain OCT by the retinal community, Jay S. Duker, MD, told colleagues at Retina 2019. Only two SS-OCT systems are available in 2019 in the U.S. — the Topcon Triton DRI and the Zeiss Plex Elite 9000. … Among clinical advantages of SS-OCT over SD-OCT are its higher speed (100,000 A-scans per second vs. 27,000 to 85,000 A-scans per second); less noise; no signal drop-off; longer imaging range (2.7 mm average vs. 2 mm ...

    1. The deeper you go with spectral domain imaging, there is more noise. That doesn't happen with swept source...They are significantly more expensive than spectral domain..."Commercial pressure” is another reason for the lack of uptake, in that, for companies that already successfully manufacture and sell OCT machines, retooling for the new technology could “cannibalize” the existing business.
