Product
Bi-Blade™+ — The advanced 25,000 CPM dual-port vitrectomy cutter designed to increase procedural efficiency, stability and control in vitreoretinal surgery.

Highlights

• 25,000 cuts per minute (CPM)
• Builds on the successes of Bi-Blade® to enable greater efficiency, stability, and control
• Supports retina surgeons in achieving consistent clinical outcomes

Why Bi-Blade™+?

• Efficiency — Higher cut rate (25,000 CPM) improves flow and reduces retinal traction, helping to streamline posterior segment procedures (vs. Bi-Blade®; based on ex vivo and in vitro testing).
• Stability — With Adaptive Fluidics™ Bi-Blade™+ helps support and maintain stable intraocular pressure (IOP) even under high vacuum.
• Control — Optimized instrument dynamics reduce sphere of influence and enable closer cutting near the retina.

Key Advantages of Bi‑Blade™+

• ≈67% increased cutter speed* (vs. prior Bi-Blade®)
• ≈25% more vitreous flow on average*†
• ≈62% reduction in average infusion pressure with Adaptive Fluidics™
• ≈62% less vibration at maximum cut speed*

*Compared to Bi-Blade®. †Based on ex vivo and in vitro testing.

Higher Standard of Performance

• Minimize sphere of influence to reduce peripheral tissue effects*
• Reduce retinal traction to help lower the risk of iatrogenic tears*
• Enhanced surgeon comfort and confidence during vitreoretinal procedures
