Effects of crystalline lens characteristics on vault after implantable collamer lens implantation.
Observational study in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeTo investigate the association between crystalline lens characteristics and postoperative vault in highly myopic eyes following implantation of Implantable Collamer Lens V4c (ICL V4c; STAAR Surgical).
settingChangsha Aier Eye Hospital, Aier Eye Hospital Group, Changsha, China.
designRetrospective observational study.
methodsThis retrospective study included 199 eyes from 199 patients who underwent ICL implantation. Crystalline lens Dimensional parameters were quantified using CASIA 2 swept-source anterior segment optical coherence tomography. Based on vault height measured 3 months postoperatively, eyes were classified into low (< 250 µm), optimal (250-750 µm), or high (> 750 µm) vault groups. Group comparisons, Spearman correlation, and multivariate logistic regression analyses were performed to identify factors associated with low vault outcomes.
resultsSignificant differences were observed in white-to-white (WTW), anterior chamber depth (ACD), anterior radius of curvature (ARC), posterior radius of curvature (PRC), lens thickness (LT), and decentration among the different vault groups (all P < 0.001). Multivariate logistic regression analysis identified a significant negative association between low vault and both ARC and lens tilt, after adjusting for age, gender and spherical equivalent (all P < 0.05).
conclusionsCrystalline Lens parameters play a critical role in determining postoperative vault following ICL implantation. Steeper anterior curvature and greater lens tilt may be anatomic indicators of a predisposition to low postoperative vault outcomes.
