Study of a Frugal Design Picosecond Laser System for Laser-Assisted Corneal Surgery.
Article in Journal of biophotonics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Femtosecond lasers have long been the gold standard for corneal laser-assisted surgery, but their high cost limits widespread use. This study challenges their supremacy by investigating a cost-effective alternative: a frugal all-fiber picosecond laser source. We first conduct a pump-probe experiment to characterize cavitation bubbles in water based on the laser pulse's temporal profile. Picosecond pulses concentrate energy in a confined volume near the focal point, allowing for more precise material interaction than femtosecond pulses. A distortion in the temporal profile, often seen as a flaw, paradoxically further reduces cavitation bubble size. These findings are then applied to ex vivo porcine cornea cutting tests. Results show that 1.5 ps pulses with a distorted profile create sharp, consistent cuts. This study reveals that a cost-effective picosecond laser can rival femtosecond lasers in precision, paving the way for more accessible corneal laser-assisted surgery.
