Sulcus fixation of a standard capsular tension ring in cataract surgery with capsular instability.

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
aimTo introduce a novel technique for stabilizing the capsular bag in cataract surgery.
methodsThis retrospective observational case series included eyes with unstable capsular bag that underwent cataract surgery. A standard capsular tension ring (CTR) with 10-0 Prolene sutures was inserted into the capsular bag and fixated to the sulcus to stabilize the bag, enabling in-the-bag intraocular lens (IOL) implantation. Uncorrected distance visual acuity, corrected distance visual acuity (CDVA), and slit-lamp examination were performed preoperatively and at 1 and 6mo postoperatively.
resultsOf the 17 eyes from 15 patients (mean age 51.20±19.60y, male/female=11/6), 8 had subluxation due to Marfan syndrome, 3 due to trauma, 5 due to zonular weakness, and 1 due to acute angle closure glaucoma. The preoperative mean CDVA (logMAR) was 0.56±0.67 (mean spherical equivalent: -6.39±4.78 D). At 1mo postoperatively, the mean CDVA improved to 0.21±0.37 (mean spherical equivalent: -0.35±1.07 D). At 6mo, the mean CDVA was 0.32±0.39, and the mean spherical equivalent was -0.34±0.99 D. All patients showed significant visual improvement at both postoperative visits (
conclusionThis technique offers a viable surgical option in complex cataract cases with zonulysis.
