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 the short-term and long-term visual and refractive outcomes between flanged intrascleral haptic fixation (FIHF) and 2-point transscleral polymethyl methacrylate (PMMA) intraocular lens (IOL) fixation using Gore-Tex sutures in patients lacking capsular support.
settingNational Cheng Kung University Hospital, Tainan, Taiwan.
designRetrospective cohort study using propensity score matching to minimize baseline differences between groups.
methodsMedical records of adult patients who underwent FIHF or Gore-Tex-sutured IOL fixation between 2014 and 2024 were reviewed. Patients with less than 12-month follow-up or conditions affecting visual prognosis were excluded. Postoperative corrected distance visual acuity (CDVA), refractive cylinder, and complications were analyzed.
results82 eyes (46 FIHF, 36 sutured) were identified; after matching, 34 eyes in each group were analyzed. After matching, the FIHF group demonstrated significantly better CDVA than the sutured IOL group at 1 month (mean logMAR, 0.73 vs 1.08; P = .003) and 3 months (0.62 vs 0.94; P = .009) postoperatively. Cylindrical power at 3 months was significantly lower in the FIHF group (1.94 vs 3.69 diopter, P = .009), indicating less surgically induced astigmatism. No significant differences were observed in CDVA, complication rates, or refractive outcomes at 12 months.
conclusionsFIHF may facilitate earlier reduction in astigmatism, thereby promoting faster visual recovery, particularly in cases of IOL subluxation or dislocation, compared with sutured IOL fixation. However, no significant differences were observed between the 2 groups in visual acuity, refractive status, or complication rates at 1 year postoperatively.
