Efficacy analysis of capsular tension ring ciliary sulcus suture fixation for lens subluxation.
Article in BMC ophthalmology, 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
objectiveTo explore the long-term therapeutic effect of capsular tension ring (CTR) suture fixation in patients with lens subluxation.
methodsA retrospective analysis was conducted on 29 (29 eyes) patients with lens subluxation who underwent phacoemulsification, in-the-bag intraocular lens (IOL) implantation, and ciliary sulcus suture fixation of the CTR at Qingdao Eye Hospital Affiliated to Shandong First Medical University from October 2019 to July 2024. The patients' postoperative best-corrected visual acuity (BCVA), refraction, intraocular pressure (IOP), complications, and IOL position were observed.
resultsAll patients were followed up for at least 12 months (range: 12-48 months). Postoperative BCVA was significantly improved compared with preoperative values (t=-7.43, P < 0.001). The average postoperative residual refractive error was 0.42 ± 0.39D (range: 0-1.25 D). Postoperative IOP was significantly lower than preoperative IOP (t = 2.42, P = 0.023). Postoperatively, 2 eyes developed dislocation of the IOL-CTR-capsular bag complex and underwent complex suspension surgery; 1 eye had transient high IOP; 1 eye had a small amount of nasal vitreous hernia; and 1 eye developed posterior capsular opacification (PCO) during follow-up, which was treated with YAG posterior capsulotomy.
conclusionCTR suture fixation can effectively improve visual acuity, maintain stable IOP, and has a low complication rate in patients with lens subluxation. It provides a safe and effective treatment method for lens subluxation.
