Posterior capsule opacification treatment using Nd: YAG laser capsulotomy: 36 months retrospective analysis.
Article in BMC ophthalmology, 2025. 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
backgroundThe study aimed to identify factors influencing the time from cataract surgery to PCO treatment with Neodymium: Yttrium-Aluminium-Garnet (Nd: YAG) laser.
methodsFor PCO risk factors analysis the retrospective study included 1045 eyes treated for PCO using Nd: YAG laser capsulotomy in the Hospital of Lithuanian University of Health Sciences (HLUHS) Kaunas Clinics with reduced best-corrected distance visual acuity (BCDVA) and opacity in the central 3 mm zone. Eyes with no comorbidities were categorized into groups according to the intraocular lense (IOL) implanted and the time from cataract operation to Nd: YAG capsulotomy was compared. Tests used for statistical analysis: Shapiro-Wilk, Kruskal-Wallis, Mann-Whitney, one-way independent ANOVA, Pearson's or Spearman's correlation coefficient, and multivariable linear regression.
resultsA total of 918 patients (1045 eyes) were included. The median time from cataract surgery to capsulotomy was 39.0 (27.4-54.6) months (min. 2; max. 174), did not differ between men and women, and was shorter for junior surgeons (25.8 (19.8-35.1) months) compared to senior surgeons (39.6 (27.8-55.3) months) (p < 0.001). Seven factors affecting the time from cataract surgery to Nd: YAG capsulotomy were found: IOL model, surgeon's experience, BCDVA after surgery, capsular tension ring, pseudoexfoliation, BCDVA before capsulotomy and exudative age-related macular degeneration (adjusted R
conclusionsThe IOL model seems to have the greatest influence on the time from cataract surgery to Nd: YAG capsulotomy. Acrylic hydrophobic IOLs with a square optical edge have different times from cataract surgery to Nd: YAG capsulotomy. Hydrophobic acrylic IOL seems to have a longer time from cataract surgery to Nd: YAG capsulotomy compared to hydrophilic acrylic IOL with a hydrophobic surface.
