Microbial contamination of therapeutic contact lenses after photorefractive keratectomy: a prospective analysis.
Article in Journal of ophthalmic inflammation and infection, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeThe objective of this study was to examine bacterial contamination in therapeutic contact lenses (TCLs) utilized following photorefractive keratectomy (PRK) and to identify factors correlated to positive culture outcomes.
methodsThis prospective study comprised 120 eyes from 60 patients who underwent bilateral PRK surgery at Farabi Eye Hospital in 2022. TCLs, applied postoperatively, were collected between the fifth and seventh days, placed in sterile containers with culture media, and analyzed for microbial growth. The documentation included patient demographic information, refractive status, preoperative conditions, culture results, and antibiotic susceptibility data.
resultsThe results indicated microbial growth was detected in seven lenses, which accounts for 5.8% of the total number of lenses (120 TCLs). Coagulase-negative staphylococci (CoNS) (4 lenses, 2 methicillin-resistant staphylococci (MRS)), Escherichia coli (E. coli) (1 lens), diphtheroid (1 lens), and micrococcus species (1 lens) were the isolated organisms. The patients did not experience any instances of microbial keratitis during the study period. Patients with positive cultures demonstrated a significantly higher mean age (35.00 ± 7.09 years, P-value = 0.036). No significant gender disparities were identified (P-value = 0.263).
conclusionThe incidence of microbial contamination in postoperative TCLs following PRK was minimal, with no occurrence of microbial keratitis. Older ages correlated with positive culture outcomes, highlighting the necessity for customized postoperative care approaches.
