Unraveling Active Surge Mitigation Actuation: Optimizing Phacoemulsification with Active Sentry Handpiece.
Article in Korean journal of ophthalmology : KJO, 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
purposeThe purpose of this study is to determine which demographic and biometric factors, lens hardness, complications such as pseudoexfoliation syndrome (PEX) and intraoperative floppy iris syndrome (IFIS), and intraoperative metrics have the greatest influence on active surge mitigation (ASM) actuation during phacoemulsification using the Centurion Vision System with the Active Sentry handpiece.
methodsThe preoperative analysis considered age, sex, biometric data (obtained using IOLMaster 700 and the Pentacam), and lens hardness according to the Lens Opacification Classification System (LOCS) III. IFIS and PEX were also assessed. Intra-operative metrics during phacoemulsification included total case time, cumulative dissipated energy, total ultrasound time, and the number of ASM actuations.
resultsSignificant positive correlations were found between ASM and both LOCS III grade (p = 0.001) and age (p = 0.017), albeit a significant negative correlation was observed with anterior chamber depth (p = 0.005). No significant differences in the number of ASM actuations were observed between genders or in patients with PEX or IFIS. In multivariate analysis, an ASM of ≥1 significantly predicted higher LOCS III grade (odds ratio, 1.79; 95% confidence interval, 1.04-2.95), whereas greater anterior chamber depth reduced this likelihood (odds ratio, 0.311; 95% confidence interval, 0.100-0.960).
conclusionsASM actuation is more frequent with advanced lens hardness and old age, while a deep anterior chamber reduces actuations compared to a shallow one. Lens hardness affects ASM more than anterior chamber depth, and no significant correlation was found between PEX, IFIS, and ASM.
