Effect of a modified soft contact lens combined with a noncontact wide-angle viewing system during vitrectomy.
Trial report in Medicine, 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
backgroundTo evaluate the efficacy of a modified soft contact lens (MSCL) in maintaining intraoperative visual clarity and protecting the cornea during vitrectomy using a noncontact wide-angle viewing system.
methodsPatients undergoing pars plana vitrectomy were randomly assigned to a balanced salt solution (BSS) group or an MSCL group. All surgeries were performed with a noncontact wide-angle viewing system. In the BSS group, the cornea was intermittently irrigated with BSS, whereas an MSCL was applied throughout surgery in the MSCL group. Surgical time, vitrectomy duration, intraoperative visual clarity, and frequency of corneal irrigation were recorded. Corneal epithelial edema, fluorescein staining, tear film breakup time, and central corneal thickness were assessed preoperatively and at 1 day, 1 week, and 1 month postoperatively. Ocular Surface Disease Index scores were evaluated preoperatively and at 1 month.
resultsThe MSCL group showed significantly better intraoperative visual clarity and corneal hydration than the BSS group (P < .05). Surgical time and vitrectomy duration were comparable between groups (P > .05). Corneal edema, fluorescein staining, and tear film breakup time at 1 day and 1 week were significantly improved in the MSCL group (P < .05), with no differences at 1 month. Ocular Surface Disease Index scores did not differ significantly between groups.
conclusionMSCL use effectively protects the cornea and improves intraoperative visualization during vitrectomy without adversely affecting postoperative ocular surface comfort.
