Positioning of intraocular lens - capsular tension ring - capsular bag complex in eyes with compromised zonules: An endoscopic observation.
Article in American journal of ophthalmology case reports, 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
Purpose: To endoscopically assess the positioning of the intraocular lens (IOL)-capsular tension ring (CTR)- capsular bag complex in relation to the ciliary body in eyes with compromised zonular support. Degisn: Prospective, interventional case series. Methods: In four eyes with fragile zonules undergoing cataract surgery, a CTR was inserted during surgery, followed by IOL implantation into the capsular bag. An ophthalmic endoscope was introduced through a temporal corneal incision to visualize the positioning of the CTR-IOL-capsular bag complex relative to the ciliary body in the 180-degree quadrant opposite the corneal incision. Results: In two eyes, the equator of the CTR-IOL-capsular bag complex contacted the area slightly below the apex of the ciliary processes. In the other two cases, the equator of the complex was secured within the ciliary sulcus across the visualized region, effectively resolving phacodonesis which had been observed preoperatively and during capsulorhexis creation. Conclusions: The exploratory study provides the endoscopic evidence that the CTR-IOL-capsular bag complex can be fixed in the ciliary sulcus in some cases, potentially enhancing postoperative stability in eyes with compromised zonules.
