1 · What the graph read from it

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.

2 · The registry

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

Robotic assistance may overcome the limitations of intraocular visualization during glaucoma surgery, particularly in eyes with corneal opacity. This preclinical study investigated the feasibility and surgical utility of a robotic-assisted intraocular endoscope-holding system for real-time visualization during Preserflo MicroShunt implantation. An endoscope-holding robot (OQrimo) enabled stable, hands-free intraocular imaging throughout the procedure. Porcine eyes were used, and corneal opacity was simulated with a black-painted contact lens. Surgical feasibility, tube-endothelium (TE) distance, and intraoperative complications were evaluated. Continuous endoscopic visualization using the robotic system enabled successful MicroShunt implantation in all eyes without complications, including intraoperative mechanical trauma to the cornea, iris, or lens. The TE distance was significantly greater in the robotic group than in the conventional group under both normal visualization conditions (1.96 ± 0.27 mm vs. 1.13 ± 0.40 mm, p = 0.009) and simulated corneal opacity (1.85 ± 0.32 mm vs. 1.12 ± 0.28 mm, p = 0.015), indicating more favorable tube positioning. These results demonstrate that robotic-assisted intraocular endoscopic visualization provides stable and precise guidance for MicroShunt implantation independent of corneal clarity. This technology has the potential to enhance surgical accuracy and expand the feasibility of minimally invasive glaucoma surgery in eyes with compromised anterior segment visualization.
