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
BACKGROUND/
objectivesThe trans-scleral four-point fixation technique was introduced to provide a stable lens fixation in patients with inadequate capsular support. This technique most commonly uses Akreos-AO or Micropure lenses with a Gore-Tex suture. This study aimed to report long term outcomes and complications of this technique. SUBJECTS/
methodsPatients who underwent insertion of a Gore-Tex sutured, scleral fixated intraocular lens between April 2019 and May 2023 in Moorfields Eye Hospital, London were identified. Operative details and postoperative outcomes were collected retrospectively from electronic case record review. Data collected included demographic details, indications for surgery, intra-operative or postoperative complications, refraction and best corrected visual acuity (BCVA).
results106 patients were included (median age 63 (17-83)). Indications were IOL complications (69/106, 65%); aphakia (18/106, 17%); or subluxed crystalline lens (19/106, 18%). Median follow-up was 77 weeks (range 10-200). Median postoperative BCVA was 0.3 LogMAR (IQR 0.2-0.6) at final visit with a median improvement of 0.4 LogMAR. The median postoperative spherical equivalent was -0.25 dioptres(D), with -1.75D astigmatism. Postoperative complications included cystoid macular oedema (8.5%), endophthalmitis (1.8%) and suture issues, including re-threading (1.8%), conjunctival resuturing (1%) or knot repositioning (4%). 10 patients had pre-existing corneal pathology and subsequently had a planned corneal graft.
conclusionGore-Tex fixated IOLs provide good visual improvement with long-term IOL stability. This series reports all patients who underwent the surgery including those performed during the learning curve and training, showing real-world outcomes.
