Posterior vitreous detachment following phacoemulsification under low intraocular pressure: a population-based OCT study.

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
purposeTo determine the prevalence and progression of posterior vitreous detachment (PVD) after phacoemulsification performed under standardized low-intraocular pressure (IOP) active fluidics with real-time surge mitigation, and to characterize age- and sex-specific PVD prevalence in the general population.
methodsAn observational, retrospective, longitudinal cohort study was developed in a private ophthalmic clinic of Tandil city, Argentina. Records of patients aged ≥40 years with axial length 22–25 mm were reviewed. A single surgeon used the Centurion system (Alcon) with Active Fluidics and Active Sentry (30 mmHg infusion, 35 cc/min flow, 350 mmHg vacuum). Posterior vitreous status was staged with widefield spectral domain optical coherence tomography (SD-OCT) using Johnson’s classification. Eyes with prior ocular surgery, ocular disease, or intraoperative complications were excluded. Minimum follow-up was 12 months.
resultsWe analyzed 1984 eyes: 432 operated and 1552 controls. Complete PVD (stage 4) increased with age and was more frequent in women ≥60 years. After ≥12 months, most eyes remained stable. Progression to stage 4 occurred in 6.9% of eyes starting at stage 0, 19.7% at stage 1, 47.8% at stage 2, and 25.0% at stage 3. In men, no differences were found between operated and control eyes; in women, excess stage 4 appeared at ages 70–79 years (73.6% vs 62.3%, p<0.01).
conclusionsUnder low-IOP active fluidics with surge mitigation, PVD progression follows biological factors (age, sex, baseline stage) rather than universal surgical acceleration. Widefield SD-OCT improves staging accuracy, and a pressure–time impulse model links fluidics dynamics to vitreoretinal traction.
