Clinical Outcomes Using a Trifocal Intraocular Lens in Eyes After Previous Laser Corneal Refractive Surgery or Radial Keratotomy: 1-Year of Follow-Up.
Article in Clinical ophthalmology (Auckland, N.Z.), 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
Purpose: To show the clinical outcomes after implantation of a diffractive trifocal intraocular lens (IOL) in eyes with previous laser-corneal-refractive-surgery (LCRS) or radial keratotomy (RK). Methods: Eyes with previous LCRS (LASIK/PRK group) or RK (RK group) implanted with a diffractive trifocal IOL were enrolled in this retrospective study. Refraction and monocular Snellen decimal uncorrected-distance visual acuity (UDVA), corrected-distance visual acuity (CDVA), and uncorrected-near visual acuity (UNVA) were analyzed at 1-year. Results: The current study comprises 124 eyes: 102 eyes for the LASIK/PRK group and 22 eyes for the RK group. In the LASIK/PRK group 92.16% of eyes were within ±0.50D and 99.02% within ±1.00D (mean spherical equivalent of -0.03±0.30D). 91.18% of eyes showed 0.50D or less astigmatism, and all of them 1.00D or less (mean refractive cylinder of -0.21±0.27D). In the RK group, 81.82% eyes were within ±0.50D and 100% within ±1.00D, with a mean SE of -0.17±0.38D. 68.18% eyes showed 0.50D or less residual astigmatism, and 95.45% eyes 1.00D or less, with a mean cylinder of -0.45±0.39D. The mean UDVA, CDVA and UNVA were 1.04±0.19, 1.14±0.20 and 0.99±0.04, respectively, for the LASIK/PRK group, and 0.90±0.10, 1.01±0.08 and 1.00±0.00, respectively, for the RK group. For the LASIK/PRK group 72.55%, 88.24% and 98.04% of eyes had 20/20 or better UDVA, CDVA and UNVA, respectively, with 96.08%, 100% and 98.04% of eyes achieving 20/25 or better for UDVA, CDVA and UNVA, respectively. For the RK group, the percentages changed to 45.55%, 83.36%, 100%, 90.91%, 100% and 100%, respectively. Conclusion: The use of a diffractive trifocal IOL can provide good clinical outcomes in eyes with previous LCRS or RK.
