Visual outcomes of Presbyopic Lens Exchange (PRELEX) with bilateral multifocal intraocular lens implantation in the Indian population.
Article 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 analyze the visual outcomes and patient satisfaction following presbyopic lens exchange (PRELEX) with bilateral implantation of multifocal intraocular lenses (MFIOLs).
methodsA single-center, multi-surgeon study involving retrospective analysis of patients with presbyopia who underwent bilateral implantation of MFIOLs with trifocal designs after phacoemulsification or femtosecond laser-assisted cataract surgery (FLACS) at a tertiary eye care hospital in South India. The visual outcomes were assessed at 2 weeks and after 6 months postoperatively, both objectively and subjectively.
resultsA total of 90 eyes of 45 patients with a mean age of 55.16 ± 6.57 years were included. 90% of the patients were hyperopic presbyopes. Postoperatively, the uncorrected distance, intermediate, and near visual acuity (VA) were logMAR 0.04 ± 0.08, 0.03 ± 0.09, and 0.11 ± 0.01, respectively, and remained stable from 2 weeks till beyond 6 months, with 82.22%, 65.55%, and 93.33% achieving a UDVA, UIVA, and UNVA of 20/20 or better at the end of follow-up. A total of 4.44% and 8.88% of the eyes required enhancement by laser refractive surgery and Nd:YAG capsulotomy for posterior capsular opacification, respectively, after a 3-month postoperative period. A total of 95.36% of the patients achieved spectacle independence, with only 15.55% complaining of glare/halos.
conclusionsPRELEX with multifocal lens implantation proves to be a safe and effective procedure that yields good visual outcomes along with patient satisfaction, especially in hyperopic presbyopes.
