Six-month performance and safety of an iris-fixated multifocal intraocular lens for presbyopia correction in phakic eyes.
Trial report in Journal of cataract and refractive surgery, 2025. 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 6-month effectiveness and safety of a new foldable multifocal iris-fixated phakic intraocular lens (pIOL) for presbyopia correction.
settingMulticenter study at 7 sites.
designNonrandomized prospective clinical trial.
methodsPresbyopic patients without cataracts undergoing bilateral multifocal pIOL implantation (Ophtec ArtiPlus) were studied. The primary outcome for efficacy was the visual acuity at distance, intermediate, and near. Secondary outcomes included endothelial cell density (ECD), postoperative refraction, binocular defocus curve, vision quality, spectacle independence, and patient satisfaction.
results49 subjects (98 eyes) were included. At 6 months, the mean binocular uncorrected distance intermediate, and near visual acuity was -0.05 ± 0.09 logMAR, -0.02 ± 0.07 logMAR, and 0.02 ± 0.08 logMAR, respectively. The ECD remained stable with a mean value of 2771 ± 289 cells/mm 2 at 6 months postoperatively. The mean spherical equivalent was -0.42 ± 0.33 diopters (D), with 95% eyes having a prediction error within ±1.0 D and 77% within ±0.5 D. The binocular distance-corrected defocus curve showed a visual acuity of 0.20 logMAR or better over a range of +1.0 to -3.5 D. Patient satisfaction was high, with a mean score of 3.5 on a 4-point scale, and 83% of the patients reported spectacle independence. 47%, 35%, and 96% of patients reported experiencing glare, halos, and starbursts at well-tolerated levels, respectively. Notably, only 2% of patients found halos and starbursts to be very bothersome.
conclusionsBilateral ArtiPlus multifocal pIOL implantation demonstrated good visual acuity from distant to near and maintained stable ECD over 6 months. Patients reported high levels of satisfaction and spectacle independence, despite some optical disturbances.
