Evaluation of the impact of cataract surgery on cognitive function in very elderly patients: a prospective, observational study.
Observational study in Aging clinical and experimental research, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
aimTo evaluate the impact of cataract surgery on cognitive function in very elderly patients (≥ 85 years).
methodsA prospective, nonrandomized, comparative study of very elderly patients (≥ 85 years), and elderly patients (≥ 65 < 85 years) scheduled for first time cataract surgery. Cognitive function, quality of life (QoL), best corrected visual acuity (BCVA), endothelial cell count (ECC), and central corneal thickness (CCT) were assessed at 90 days before surgery (T0), at surgery (T1), and at 30 (T2) and 90 days (T3) after surgery. Macular thickness (MT) was evaluated at T2. Six-item cognitive impairment test (6CIT) was used to evaluate cognitive function while the Catquest-9SF test was used to assess QoL. The confusion assessment method (CAM) was used to evaluate the presence of delirium episodes at within 48 h from T1.
resultsA total of 78 patients (very elderly n = 24, elderly n = 54) were enrolled; average age 80.3 ± 6.2 years old. Significant improvements for cognitive function, BCVA, QoL (p < 0.01) during the observational period were observed among the cohort. A greater improvement in cognitive function was observed in the very elderly patients between T1 and T2 (p = 0.02), while there was no difference in BCVA and QoL between the groups. There were no significant differences in ECC and CCT changes between the groups. No delirium episodes or significant macular abnormalities were registered.
conclusionsCataract surgery in very elderly patients seems to offer a greater improvement in cognitive function as compared to elderly patients, and it is associated with a significant improvement in QoL, without any incidence of postoperative delirium.
