Effect of Intracameral Air Bubble Injection on Early Visual and Intraocular Pressure Outcomes After Phacoemulsification.
Article in Cureus, 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 evaluate the efficacy of intracameral air bubble injection in enhancing visual acuity following phacoemulsification cataract surgery.
methodsA prospective quasi-experimental study was conducted on 98 eyes from 78 participants who underwent phacoemulsification at SMEC Eye Hospital, Medan, between March and August 2025. All surgeries were performed by a single surgeon using the phaco-chop technique with bimanual irrigation/aspiration and intraocular lens (IOL) hydro-implantation using a Venturi phaco machine (Bausch+Lomb, Bridgewater, NJ, USA). At the conclusion of the surgery, 0.5% levofloxacin was administered intracamerally for infection prophylaxis, followed by air bubble injection. Postoperative outcomes included uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and intraocular pressure (IOP), analyzed using paired t-tests (95% CI; p<0.05).
resultsUCVA improved significantly from logMAR 0.823 ± 0.113 (0.602-1.301) to 0.103 ± 0.073 (0.000-0.397) (p<0.001). BCVA improved from logMAR 0.651 ± 0.108 (0.477-0.903) to 0.083 ± 0.079 (0.000-0.176) (p<0.001). Mean IOP decreased from 17.23 ± 1.52 mmHg (16-20) to 13.26 ± 1.21 mmHg (11-16) (p<0.001). Minimal corneal edema and no significant inflammation were observed.
conclusionIntracameral air bubble injection at the end of phacoemulsification significantly improves UCVA and BCVA, lowers IOP, and minimizes corneal edema. This simple, safe, and reproducible technique represents a valuable adjunct to cataract surgery for optimizing postoperative visual outcomes and patient satisfaction.
