Standard Automated Perimetry Before and After Extended Depth-of-Focus Intraocular Lens Implantation: Longitudinal Changes in Global Indices and Test Reliability.

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
Purpose: To describe changes in standard automated perimetry (SAP) parameters before and after extended depth-of-focus (EDOF) intraocular lens implantation (Symfony) in a longitudinal before-and-after design. Methods: Patients undergoing cataract surgery with EDOF IOL implantation were evaluated with SAP preoperatively (baseline) and postoperatively (6-12 months after surgery). Thirteen patients (23 eyes) completed both examinations. The right and left eyes were analyzed separately. Outcomes included foveal threshold, mean deviation (MD), pattern standard deviation (PSD), visual field index (VFI), and reliability indices (false-positive and false-negative rates). Data were summarized as mean ± standard deviation (SD) and compared between time points using paired tests. SAP was performed with the Humphrey Field Analyzer II using the SITA Standard 24-2 strategy. Results: SAP outcomes showed small, non-significant changes from baseline to follow-up. MD improved slightly (right: -1.1 ± 1.2 to -0.8 ± 1.2 dB, p = 0.32; left: -1.9 ± 0.9 to -1.2 ± 1.1 dB, p = 0.12). VFI remained stable (right: 99.1% ± 1.1% to 98.8% ± 1.4%, p = 0.43; left: 98.0% ± 1.1% to 98.0% ± 2.1%, p = 1.00). Foveal threshold was unchanged (right: 35.1 ± 1.9 to 35.2 ± 0.9 dB, p = 0.86; left: 34.0 ± 1.0 to 34.5 ± 1.3 dB, p = 0.26). PSD showed no significant variation (right: 1.9 ± 0.9 to 1.7 ± 0.4 dB, p = 0.34; left: 1.8 ± 0.3 to 1.9 ± 1.2 dB, p = 0.73). Reliability indices were also stable: false positives (right: 1.9% ± 2.6% to 2.1% ± 1.4%, p = 0.75; left: 1.4% ± 2.5% to 0.5% ± 0.6%, p = 0.21) and false negatives (right: 1.6% ± 2.1% to 1.7% ± 3.1%, p = 0.91; left: 2.2% ± 2.9% to 1.1% ± 1.5%, p = 0.35). Conclusion: In this longitudinal before-and-after evaluation, EDOF IOL implantation was not associated with clinically meaningful changes in SAP outcomes, with stable global indices, foveal threshold, and reliability measures.
