Successful Management of a Keratoconus Patient With Rarely Used Large-Diameter Corneal RGP Contact Lenses: A Case Report.
Article in Cureus, 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
Keratoconus is a degenerative corneal disease that is usually bilateral and asymmetric. In keratoconus, the cornea progressively thins and steepens, leading to vision impairment. This unique case report highlights the management of a keratoconus patient with infrequently used large-diameter corneal RGP contact lenses. This method of fitting provides remarkable stability and patient comfort. Here, I describe a case of a 39-year-old man with a known history of keratoconus. He was referred to our contact lens clinic for management with RGP lenses. Throughout the eye exam, the patient was deemed eligible to wear RGP contact lenses. Uncorrected visual acuity was 20/400 in the right eye and 20/400 in the left eye. Visual acuity improved to 20/40 in the right eye with a correction of -6.00/-3.00 x 90 and to 20/30 in the left eye with a correction of -6.00/-2.00 x 95. I fitted this patient with large-diameter (10.30 mm) corneal RGP lenses in both eyes, and the fitting was optimal, resulting in a significant improvement in visual acuity to 20/20 in each eye. This case study aims to document the success of large-diameter corneal RGP contact lenses in the management of keratoconus.
