1 · What the graph read from it

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.

2 · The registry

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 prospectively evaluate the safety and efficacy of a novel surgical technique for removing metallic intraocular foreign bodies (IOFBs) in eyes with concomitant traumatic cataract, utilizing a magnetic probe introduced through a limbal incision to directly extract the IOFB in a single pass.

methodsThis prospective, interventional case series included 21 consecutive eyes of 21 patients presenting with posterior segment IOFBs and traumatic cataracts. The standardized procedure involved: primary phacoemulsification, creation of a central posterior capsulotomy (posterior vitrectorhexis), pars plana vitrectomy (PPV) to mobilize the IOFB, and introduction of a 19-gauge intraocular magnet through the main limbal corneal incision. The magnet was passed through the posterior capsulotomy to directly engage and remove the IOFB via the same limbal route. Main outcome measures were successful IOFB removal, incidence of intraoperative complications (particularly IOFB slippage and iatrogenic retinal injury), postoperative complications, and best-corrected visual acuity (BCVA).

resultsThe novel technique was successfully performed in all 21 eyes (100%) without the need for intraocular instrument relay. The mean IOFB size was 3.5 ± 1.6 mm. No cases of intraoperative IOFB slippage or iatrogenic retinal injury occurred. Preoperatively, 17 eyes (81.0%) had a BCVA worse than 20/200. Postoperatively, 17 eyes (81.0%) achieved a BCVA of 20/40 or better. No cases of postoperative retinal detachment or endophthalmitis were observed. Transient macular edema and epiretinal membrane occurred in one case each (4.8%).

conclusionThe magnetically guided single-pass limbal extraction technique represents a safe, effective, and streamlined approach for removing IOFBs in the setting of traumatic cataract.
