Evaluating the effects of trifocals and extended depth of focus intraocular lens implantation on stereopsis and contrast sensitivity in cataract patients.
Trial report in Indian journal of 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 compare the effects of trifocal and extended depth of focus (EDOF) intraocular lenses (IOLs) on stereopsis and contrast sensitivity following cataract surgery.
methodThis randomized, prospective, comparative study was conducted at the cataract department of a tertiary eye hospital. A total of 70 patients scheduled for cataract extraction were randomly assigned to two groups. Group 1 received AcrySof IQ PanOptix trifocal IOLs, while Group 2 received AcrySof IQ Vivity EDOF IOLs. Comprehensive evaluations were performed preoperatively and postoperatively at 1 week and 1 month.
resultsAt 1 week postoperatively, both trifocal IOLs and EDOF IOLs demonstrated comparable outcomes in contrast sensitivity and stereopsis. At 1 month, stereopsis was significantly better in the EDOF group (89.14 ± 46.86 arc sec) than in the trifocal group (118.28 ± 44.81 arc sec; P = 0.017). Contrast sensitivity improved significantly in the EDOF group ( P = 0.023) but remained stable in the trifocal group. Intergroup contrast sensitivity differences were not statistically significant.
conclusionBoth IOLs provided good stereopsis and contrast sensitivity in the early postoperative period. However, by 1 month, EDOF IOLs demonstrated significantly better stereopsis and improved contrast sensitivity.
