Ultrafast laser bone ablation towards high surgical speeds and clinically relevant operation times for spine surgeries.
Article in Biomedical optics express, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Recent advancements in ultrafast laser ablation technology redefine surgical precision while minimizing thermal damage, offering a promising alternative to traditional methods. However, the slow material removal rates (MRRs) have hindered clinical adoption. Addressing this challenge, we present a compact fiber-based laser delivery system, exhibiting an 82-fold increase in MRR compared to previous femtosecond laser probes. The system leverages a hollow-core Kagome fiber to deliver 10 ps laser pulses with high transmission efficiency and minimal nonlinear effects, even at high peak powers. The system distributes ultrashort pulses utilizing a piezo-scanned Lissajous-based beam steering mechanism onto the target surface over a larger field-of-view (FOV), enabling the scope for easy scalability of the system to a miniaturized probe. Drawing insights from our prior work, the focusing optics were carefully selected to deliver fluence three times the ablation threshold. An optimal combination of FOV size, translation speed, and repetition rate was identified, enabling clean ablations (devoid of carbonization) even at maximum laser power. We achieved a maximum MRR of 10.7 mm
