Changes in Visual Acuity and Dry Eye Parameters Following One Month of Scleral Lens Wear in Patients with Keratoconus: A Prospective Observational Study from Saudi Arabia.

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
BACKGROUND/
objectivesTo evaluate the immediate visual correction provided by scleral lens insertion and short-term changes in ocular surface parameters associated with one month of scleral lens wear in patients with keratoconus in Saudi Arabia.
methodsThis prospective observational study included 18 participants with keratoconus (18 study eyes). Scleral lenses were fitted bilaterally, while one eye per participant was selected for ocular analysis; when both eyes were eligible, the eye with the higher Kmax was selected. Participants were instructed to wear ONEFIT MED
resultsAll 18 participants completed follow-up. Mean logMAR visual acuity improved immediately after lens insertion from 0.723 ± 0.550 to 0.089 ± 0.126 at baseline and from 0.760 ± 0.544 to 0.099 ± 0.126 at one month (both
conclusionsScleral lenses provided substantial immediate visual correction, while one month of regular wear was associated with reduced dry eye symptoms and modest changes in tear secretion and tear-film stability. Because this was an uncontrolled observational study, the ocular-surface findings should be interpreted as associations rather than causal effects.
