Long-term outcomes of sutured and sutureless (Yamane) scleral-fixated intraocular lens implantation for lens subluxation in Marfan syndrome: a retrospective case series.
Article in BMC 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 describe scleral-fixation surgical approaches in patients with Marfan syndrome and lens subluxation and to evaluate postoperative visual outcomes and complications.
designRetrospective case series.
methodsMedical records of 9 patients (15 eyes) with Marfan syndrome who underwent surgery for lens subluxation between January 2015 and March 2023 were retrospectively reviewed. Surgical techniques included sutured scleral fixation, sutureless intrascleral fixation (Yamane technique), and vitrectomy-assisted procedures when indicated. Preoperative and postoperative best-corrected visual acuity (BCVA), postoperative complications, secondary interventions, and intraocular lens (IOL) position were analyzed. Outcomes according to fixation technique were assessed descriptively due to small and unbalanced subgroup sizes.
resultsSutured scleral fixation was performed in 13 eyes, while sutureless intrascleral fixation using the Yamane technique was applied in 2 eyes. The mean patient age was 15.46 ± 15.88 years (range, 5-70 years), and the mean follow-up duration was 30.66 months (range, 7-120 months). BCVA improved significantly from 1.28 ± 0.76 logMAR preoperatively to 0.69 ± 0.80 logMAR postoperatively (p = 0.01). Postoperative complications occurred in 4 eyes (26.7%), including retinal detachment in one eye (6.7%) and intraocular lens subluxation or pupillary capture in three eyes (20%). All complications were successfully managed with secondary surgical interventions. Visual improvement was limited in two eyes due to pre-existing amblyopia.
conclusionScleral-fixated intraocular lens implantation is an effective option for visual rehabilitation in patients with Marfan syndrome and lens subluxation. However, observed complication patterns highlight the importance of individualized surgical planning and long-term postoperative surveillance. Comparisons between fixation techniques should be interpreted as descriptive.
