Rescue of a dislocated intraocular lens with silicone tip aspiration: a novel technique.
Article in BMC ophthalmology, 2025. 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
backgroundTo evaluate the clinical efficacy of a novel surgical technique using a 25-gauge active aspiration of flute needle for treating the dislocation of posterior intraocular lens (IOL).
methodsThis retrospective study included 12 eyes in 12 patients with posterior dislocated IOL. All patients underwent comprehensive ophthalmic evaluations before surgery. Surgery was performed with three-port pars plana vitrectomy, the dislocated IOL was aspirated to the anterior vitreous by a 25-gauge flute needle, and then managed by different surgical corrections. Comprehensive ophthalmologic assessment was performed preoperatively and postoperatively, including best-corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp biomicroscopy and fundus examination. Postoperative assessments were conducted at 1 week, 1 month, and 3 months.
resultsTwelve eyes were treated. All surgeries were successfully completed using a 25-gauge silicone tip with active aspiration. IOL repositioning without sutures in 1 case (8.3%), IOL repositioning with scleral sutures in 4 cases (33.3%), IOL exchanged with Yamane technique in 4 cases (33.3%) and IOL exchange with scleral sutures in 3 cases (25.0%). The mean follow-up time was 13.08 ± 5.49months (range 5–20 months). The mean BCVA preoperatively was log MAR 0.48 ± 0.33 (range 0.0-1.3), recovered to log MAR 0.34 ± 0.22 (range 0.0-0.7) at three-month postoperatively. The BCVA was improved at the three-month follow-up compared with preoperatively (t = 2.40, P = 0.035 < 0.05). IOP remained stable except for one patient who developed transient high IOP, but well controlled by medications.
conclusionsAn active aspiration of flute needle with silicon tip provides a simplified, efficient and safe method for IOL dislocation, minimizing the needs of perfluorocarbon liquids as well as intraocular-forceps.
