Database evaluation of complication rates and visual outcomes of cataract surgery performed by trainees vs independent surgeons.
Article in Journal of cataract and refractive surgery, 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 complication rates and visual outcomes of cataract surgery performed by trainees vs independent surgeons.
setting8 UK clinical centers.
designRetrospective multicenter clinical database study.
methods15-year data of 35 558 cataract surgeries undertaken by trainees and 77 131 by independent surgeons were evaluated for the rate of operative complications with emphasis on posterior capsule rupture (PCR) and logMAR distance visual acuity (VA) (defined as best available value of uncorrected or corrected VA) at 4 to 12 weeks. Recording of intraoperative complications was robust using a predetermined list of cataract surgery complications in the electronic medical record.
resultsTrainees operated on less complex eyes, with lower rates of advanced cataracts and poor pupillary dilation ( P < .001). Trainee surgeries had a significantly higher rate of PCR (2.4% vs 1.3%) compared with independent surgeons. Junior trainees had the highest PCR rate at 3.87%, compared with senior trainees at 2.12%. Using the funnel plot methodology, most surgeons seemed to approach the overall mean of PCR, 1.9%, at a surgical volume of approximately 150 cases. At 4 to 12 weeks postoperatively, there was no significant difference in the mean logMAR VA between both groups (0.197 vs 0.200, Snellen equivalent ∼20/30, P = .095).
conclusionsPCR should be the primary metric for assessing the quality of trainee-performed cataract surgery rather than VA outcomes. Funnel plot representation of PCR provides an equitable approach for monitoring trainees' surgical progress and peer-to-peer comparisons.
