Impact of surgeon experience on corneal endothelial changes after cataract surgery.
Article in Arquivos brasileiros de oftalmologia, 2025. 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 endothelial corneal cell changes following cataract surgery performed by phacoemulsification with intraocular lens implantation, conducted by surgeons with varying levels of experience.
methodsTwo hundred and eighty-three eyes diagnosed with cataract were included. Lens opacity was classified into three categories (I, II, and III). Surgeons were categorized into four experience levels (1, 2, 3, and 4), based on years of practice and lifetime surgeries performed. Corneal endothelial characteristics were assessed using non-contact specular microscopy, with measurements taken before surgery and 30-60 days post-surgery.
resultsPreand postoperative endothelial analysis showed no significant differences between surgeon levels regarding visual acuity achieved, corneal thickness, and endothelial hexagonality. However, the central endothelial cell density index showed a significantly greater reduction among level 1 surgeons (p=0.026). Grade II cataracts exhibited significant variations in the central endothelial cell density (p=0.011) and average cell size, with level 1 surgeons showing the largest increases (p=0.024).
conclusionsThe analysis revealed significant differences in visual acuity and endothelial indices between surgeon experience levels, with less experienced surgeons showing greater variations and poorer performance. Clinical protocols should consider these data to establish safer training protocols.
