Visual outcome of a diffractive trifocal intraocular lens in eyes with short axial length.
Observational study 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
purposeThis study aimed to investigate the visual quality of short-axial length cataractous eyes after bilateral implantation of the trifocal intraocular lens (IOL) AcrySof IQ PanOptix.
methodsThis prospective observational study enrolled bilateral short-axial lengths (≤ 22.5 mm) cataract patients after implantation of IOL AcrySof IQ PanOptix. Monocular and binocular uncorrected distance, corrected distance, uncorrected intermediate (60 cm), distance-corrected intermediate, uncorrected near (40 cm), and distance-corrected near (UDVA, CDVA, UIVA, DCIVA, UNVA and DCNVA) visual acuity were measured with follow-up of three months. Visual disturbances, patient satisfaction and spectacle independence were assessed using a questionnaire.
resultsThe study included 40 patients with a total of 80 eyes, with 80.0% female. The average axial length was 22.05 ± 0.39 mm. Monocular UDVA were 0.05 ± 0.09, CDVA were 0.00 ± 0.07, UIVA were 0.09 ± 0.10, DCIVA were 0.04 ± 0.08, UNVA were 0.11 ± 0.13 and DCNVA were 0.05 ± 0.09. Binocular UDVA were 0.02 ± 0.08, CDVA were − 0.02 ± 0.05, UIVA were 0.03 ± 0.08, DCIVA were 0.00 ± 0.06, UNVA were 0.02 ± 0.06 and DCNVA were 0.02 ± 0.06. Regarding adverse visual phenomena, 37.5% of patients reported significant starbursts and 27.5% reported significant halos. However, overall satisfaction reached 95%, with all patients achieving complete spectacle independence.
conclusionsWith detailed preoperative evaluation, the trifocal IOL provided satisfactory visual outcomes for patients with short-axial length. Since the trifocal IOL can significantly improve the symptoms of hyperopia and presbyopia, patient satisfaction may be higher.
