Quantitative analysis of posterior chamber morphology on vault after ICL implantation: a retrospective paired study.
Article in International journal of 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
aimTo quantitatively evaluate the influence of four posterior chamber morphological features-wide iris-ciliary angle (ICA), concave iris (CI), anteriorly positioned ciliary body (APCB), and ciliary body cyst (CBC)-on vault after implantable Collamer lens (ICL) implantation.
methodsIn this retrospective paired study, 925 eyes from 506 patients were analyzed. Participants were matched 1:1 based on ICL size, horizontal/vertical sulcus-to-sulcus (STS) diameters, and lens thickness. Posterior chamber morphology was assessed using ultrasound biomicroscopy (UBM). Actual vault measurements were compared against vault values predicted using the Zhu formula. Statistical analyses included paired
resultsEyes with wide ICA (
conclusionPosterior chamber morphology, particularly wide ICA, CI, and APCB, significantly affects postoperative vault. These features introduce systematic deviations in vault prediction, highlighting the need for integrating morphological parameters into ICL sizing algorithms to optimize surgical outcomes and reduce complications.
