SLD vs Swept-Source Technology in Optical Biometers – Why Huvitz HBM-1 Took a Smarter Route

When investing in an optical biometer, you’ll often face a choice between two core technologies:

Swept-Source OCT and Super Luminescent Diode (SLD).

At first glance, swept-source may appear superior for its deep tissue penetration, but is it really necessary in 2025?

The Reality in Clinics Today

As Huvitz discovered during development of the HBM-1:

• Incidence of dense cataracts is declining, thanks to earlier detection and intervention.

• The majority of OPD cataract patients fall within NS1–NS3 grade, which SLD handles reliably.

• Swept-source systems are costlier, increasing the per-patient ROI burden.

  
  

Huvitz’s Solution: SLD + DCM Mode

Rather than follow the trend, Huvitz innovated on its own path:

• SLD-based technology, enhanced with DCM (Dense Cataract Mode), offers 10% better penetration than standard SLDs.

• It covers up to 80–85% of OPD cataract patients, reducing the need for fall back ultrasound scans.

• And importantly, it keeps the focus on accurate corneal measurements - essential for premium IOL and topography-driven surgeries.

  
  

Final Takeaway

Swept-source may look good on paper, but for most real-world practices, SLD + DCM is more cost-effective, accurate, and sufficient. The HBM-1 proves you don’t need to overspend to get premium-grade biometry.

So, SLD vs Swept Source technology, what's your take?
