Comparison of Postocclusion Pressure Surge Between Pressure Sensing and Traditional Phacoemulsification Handpieces.
Article in Journal of ophthalmology, 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
Purpose: To compare the Active Sentry and OZil handpieces regarding their ability to prevent postocclusion surge. Setting: John A. Moran Eye Center, University of Utah, Salt Lake City, Utah. Design: Experimental study. Methods: This study used the Alcon Centurion surgical platform, with both OZil handpieces fitted with balanced tips. The quad preset was used with a vacuum of 500 mmHg, an aspiration flow of 50 mmHg, and an intraocular pressure (IOP) of 70 mmHg. A rubber disk was fixed within a sealed chamber fitted with an electric pressure sensor to monitor pressure changes. The phaco tip was inserted through a small opening, and the foot pedal was set to position two. The tip was put in contact with the fixed rubber disk to replicate tip occlusion and then pulled from the disk to simulate occlusion break. 10 trials were performed with each handpiece, and pressure changes were recorded electronically. Results: A significant difference ( Conclusion: The Active Sentry handpiece was found to have a decreased magnitude and shorter duration of postocclusion surge compared with the OZil, signifying that having the pressure sensor in the handpiece allows it to react to post-occlusion surge more quickly and to decrease surge magnitude.
