Restoring functional vision in moderate-advanced keratoconus: quality-of-life outcomes with hybrid contact lenses.
Article in International ophthalmology, 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
purposeTo evaluate the clinical, functional, and quality-of-life outcomes of next-generation SynergEyes UltraHealth® hybrid contact lenses (HCLs) in patients with moderate to advanced keratoconus or irregular astigmatism who failed to achieve adequate visual rehabilitation with conventional optical correction methods.
methodsThis retrospective study included 31 patients diagnosed with keratoconus or irregular astigmatism who were intolerant of, or inadequately corrected with, silicone hydrogel soft lenses, or rigid gas-permeable (RGP) lenses. During follow-up, 3 patients (6 eyes) discontinued HCL use due to intolerance, leaving 53 eyes of 28 patients for analysis. All patients were fitted with SynergEyes UltraHealth® HCLs. Best corrected visual acuity (BCVA) with RGP lenses or soft lenses and HCL-corrected visual acuity (HCVA) were recorded at baseline and at 6 months. Kmax, central corneal thickness, and apex values were recorded using Pentacam®. Vision-related quality of life was assessed using the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25).
resultsThe mean Kmax was 58.5 ± 6.3 D, indicating predominantly moderate-to-advanced keratoconus. HCVA improved significantly from 0.42 ± 0.22 logMAR to 0.13 ± 0.11 logMAR (p = 0.02). HCVA of 0.22 logMAR or better was achieved in 88.6% of eyes. NEI-VFQ-25 scores demonstrated marked improvements, particularly in general vision, near and distance activities, social functioning, and vision-related mental health (all p < 0.05). Additionally, there was an increase in eye pain scores (higher scores indicate less pain according to this scale), with higher scores associated with better outcomes; only three patients (six eyes) discontinued hybrid contact lens use due to intolerance, and no serious eye complications were observed.
conclusionNext-generation hybrid contact lenses provide significant improvements in visual acuity and vision-related quality of life in patients with advanced keratoconus and irregular astigmatism. SynergEyes UltraHealth® lenses are an effective and well-tolerated alternative, particularly for patients intolerant of RGP lenses.
