Multifocal toric IOL implantation in a patient with Alport syndrome, anterior lenticonus, and intermittent exotropia: a case report.
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
backgroundAlport syndrome is a hereditary disorder characterized by renal failure, sensorineural hearing loss, and ocular manifestations. Anterior lenticonus is the most pathognomonic ocular feature, whereas strabismus is rarely reported. Intraocular lens (IOL) implantation in such patients can be challenging due to lens capsule fragility and coexisting visual problems. CASE PRESENTATION: We report a patient with Alport syndrome presenting with anterior lenticonus and intermittent exotropia, who underwent sequential bilateral phacoemulsification with multifocal toric IOL implantation. Preoperative examination revealed high myopic astigmatism and reduced visual acuity. Strabismus evaluation showed intermittent exotropia with greater deviation at near. Surgery was performed with meticulous hydrodelineation and careful capsulorrhexis. A multifocal toric IOL was successfully implanted and oriented along the intended axis. At the 6-month postoperative follow-up, uncorrected distance visual acuity was maintained at 0.05 LogMAR (Snellen 20/22) and uncorrected near visual acuity was N5 at 40 cm in both eyes; no severe visual disturbances were detected, and no complications such as capsular contraction or IOL decentration were observed.
conclusionBilateral trifocal toric intraocular lens implantation may provide satisfactory visual rehabilitation in selected patients with Alport syndrome and anterior lenticonus, even in the presence of coexisting intermittent exotropia.
