Utilizing PROSE as a Drug Delivery Device for Preservative-Free Cyclosporine 0.05% for the Treatment of Dry Eye Disease: A Pilot Study.
Trial report in Clinical ophthalmology (Auckland, N.Z.), 2024. 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
Purpose: To evaluate the tolerability of utilizing Prosthetic Replacement of the Ocular Surface Ecosystem (PROSE) as a drug delivery device for preservative-free cyclosporine 0.05% for the treatment of dry eye disease. Patients and Methods: Fourteen current daily PROSE wearers were enrolled, with four screen failures and one subject that did not complete the study protocol due to burning and stinging. Nine subjects, 18 eyes completed the study protocol. All participants were instructed to instill one drop of preservative-free cyclosporine 0.05% in the PROSE reservoir and then fill the rest of the reservoir with preservative-free normal saline. After applying the PROSE and wearing for 6 hours, the PROSE was removed, and the protocol was repeated for at least another 4 additional hours of wear. Baseline, 1 week and 1 month symptom and sign data were collected. Results: At one month, OSDI improved by an average of 3.83 ± 6.87 from baseline (p = 0.07) and there was no statistically significant change in best corrected visual acuity. Without comparing with placebo, there was statistically significant (p < 0.05) improvement in mean per subject and mean per eye corneal fluorescein staining, conjunctival lissamine staining, and conjunctival hyperemia by slit lamp examination at one-month follow-up. Conclusion: Utilizing PROSE as a drug delivery system for non-preserved cyclosporine 0.05% was well tolerated in regard to both ocular symptoms and ocular surface signs. Results from this pilot study are suggestive of efficacy. The results of this study support progressing this protocol to a larger scale randomized controlled double blinded prospective clinical trial.
