Comparison of Effective Phacoemulsification Times Used in Cataract Surgery between the Veritas Vision System and the Centurion Vision System.
Article in Korean journal of ophthalmology : KJO, 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
purposeTo compare the effective phacoemulsification time (EPT) used in cataract surgery and postoperative outcomes between the Veritas Vision System and the Centurion Vision System.
methodsA retrospective analysis was conducted on 90 eyes from 82 patients with senile cataracts who underwent cataract extraction by phacoemulsification at Samsung Medical Center from December 2022 to May 2023. According to the Lens Opacities Classification System III grading of nucleus opalescence (NO), eyes with grades 3 to 5 were included, subdivided into moderate (≥NO3, <NO4) and hard (≥NO4, ≤NO5) cataracts. The Veritas Vision System was utilized for 43 eyes, comprising 26 moderate and 17 hard cataracts, while the Centurion Vision System was utilized for 47 eyes, including 26 moderate and 21 hard cataracts. Intraoperative parameters were ultrasound time (sec), average phacoemulsification power (%), and EPT (%·s) for the Veritas group; and cumulative dissipated energy (CDE, %·s) for the Centurion group. Best-corrected visual acuity (BCVA) and endothelial cell counts (ECC) were measured one month postoperatively. All parameters were compared between the subgroups.
resultsIn both the moderate and hard cataract groups, the EPT in the Veritas group was lower than the CDE in the Centurion group (p = 0.035 and p = 0.009, respectively). However, no significant differences in postoperative BCVA or ECC changes were observed.
conclusionsThe Veritas Vision System demonstrated lower EPTs in the moderate and hard cataract groups. Both systems showed effective and safe surgical outcomes.
