Clinical Outcomes of Secondary Intraocular Lens Scleral Fixation after Acute Secondary Angle-Closure Caused by Lens Subluxation.
Article in Korean journal of ophthalmology : KJO, 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 describe the clinical characteristics and evaluate the surgical outcomes of patients with acute secondary angle-closure associated with lens subluxation who underwent phacoemulsification with secondary intraocular lens (IOL) scleral fixation.
methodsA retrospective study was performed on patients with unilateral lens subluxation with angle-closure who underwent phacoemulsification with secondary IOL scleral fixation using the single-loop 4-point technique, and were followed up for at least 2 years. A total of 22 affected eyes from 22 patients were enrolled in this study. Preoperative ocular biometric parameters of affected eyes were compared with those of unaffected fellow eyes. Changes in intraocular pressure (IOP) were evaluated during the 2-year follow-up period.
resultsAmong the affected eyes, 72.7% were in male patients and 63.6% involved the left eye. A history of ocular trauma was present in approximately 9.1% of patients. Preoperatively, affected eyes showed higher peak IOP (34.27 mmHg in the affected eye vs. 16.05 mmHg in the fellow eye), shallower anterior chamber depth (1.90 mm in the affected eye vs. 2.82 mm in the fellow eye), and more myopic spherical equivalent (-1.27 diopters [D] in the affected eye vs. 0.10 D in the fellow eye) compared to fellow eyes. Postoperative IOP remained stable for up to 2 years; however, 54.5% of patients required more than one antiglaucoma medication during this period. All affected eyes achieved the target IOP of <21 mmHg without requiring further glaucoma filtration surgery, although 54.5% of patients necessitated ongoing antiglaucoma medication (qualified success).
conclusionsIn eyes with lens subluxation-associated secondary angle-closure, phacoemulsification with secondary IOL scleral fixation resulted in stable IOP control and anatomical restoration over a 2-year follow-up period in severe cases with extensive zonular dialysis.
