Acute Effects of Cigarette Smoking on Corneal Tomographic and Biometric Parameters: A Prospective Controlled Study.
Article in Beyoglu eye journal, 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
Objective: To evaluate the acute effects of cigarette smoking on corneal tomography and ocular biometry. Methods: This prospective, controlled study included 92 healthy volunteers (46 smokers and 46 non-smokers); only the right eye was analyzed. Baseline ophthalmological examination, corneal tomography and biometry were performed. Participants remained outdoors for 10 minutes under standardized conditions; smokers smoked one cigarette, whereas controls did not. Measurements were then repeated, and within-group changes and between-group differences in change (Δ) were analyzed. Results: Baseline demographic, tomographic, and biometric measurements were similar between groups (all p>0.05). Within the smoking group, significant reductions were observed in corneal thickness at the pupil center, corneal vertex, and thinnest point (p=0.011, p=0.012, and p=0.017, respectively). Within the smoking group, anterior chamber depth also decreased from 3.08±0.44 mm to 2.98±0.52 mm (p=0.034); however, the between-group difference in Δ values was not statistically significant (p=0.068). In contrast, no significant changes were observed in anterior chamber volume, keratometric values, axial length, or emmetropia-targeted intraocular lens power calculated using the Barrett Universal II formula (p>0.05 for all). No significant changes were observed in any of the parameters examined in the control group. In the between-group comparison of Δ values, changes in pupil-center pachymetry and thinnest corneal thickness were significantly different (p=0.002 and p=0.004). Anterior 0-2 mm densitometry decreased in smokers, with a significant between-group difference in Δ (p=0.029). Conclusions: Acute cigarette smoking was associated with measurable alterations in corneal thickness, anterior chamber depth and several corneal densitometry parameters. However, these changes did not significantly affect keratometric values, axial length, or intraocular lens power calculations. Recent cigarette smoking may affect anterior segment measurements, and recent cigarette smoking should be considered when interpreting measurements, especially in situations requiring sensitive corneal assessment.
