Clinical outcomes of 27-gauge needle-guided flanged intrascleral haptic fixation using the yamane technique in various indications.

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 describe the clinical outcomes and complications of intrascleral haptic fixation using the Yamane technique in patients with aphakia and intraocular lens (IOL) dislocation.
methodsThis study retrospectively examined 37 eyes of 37 patients who underwent Yamane surgery for aphakia or a dislocated IOL at a tertiary teaching hospital and had a follow-up period longer than 6 months. Demographic data, Yamane indication, ocular comorbidities, and additional surgical procedures performed were recorded. Preoperative and postoperative distance visual acuity (VA), refractive results, intraocular pressure (IOP), central macular thickness measurements, and postoperative complications were recorded.
resultsThe mean age of the patients was 68.5 ± 13.1 years, and the mean follow-up period was 9.05 ± 3.36 months. The Yamane indication was aphakia in 24 (64.9%) patients and IOL dislocation in 13 (35.1%) patients. Anterior vitrectomy was performed in 19 patients (51.4%), capsular tension ring extraction in 2 patients (5.4%), IOL extraction in 7 patients (19.0%), and pars plana vitrectomy in 8 patients (21.6%). The mean subjective refraction improved from 8.70 ± 4.83 to -1.36 ± 0.41 diopter (D) at the final visit (p = 0.001). The mean cylindrical refraction was - 1.41 ± 1.05 D in the postoperative period. The mean best corrected VA improved from 0.53 ± 0.22 to 0.15 ± 0.09 logMAR (p = 0.001). Postoperatively, corneal edema was observed in two patients (5.4%), cystoid macular edema in two patients (5.4%), epiretinal membrane in two patients (5.4%), hypotony in one patient (2.7%), elevated IOP in two patients (5.4%), and iris capture of IOL in one patient (2.7%).
conclusionThe Yamane technique has provided favorable visual and refractive outcomes with manageable postoperative complications in patients with aphakia and IOL dislocation, including complex cases requiring additional intervention such as vitreoretinal surgery.
