Evaluation of Short-Term Safety and Efficacy of Myopia Correction with a Novel Posterior Chamber Phakic Intraocular Lens.

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
introductionThis study aims to evaluate the short-term safety and efficacy of the Loong Crystal
methodsThe single-center retrospective case series included 67 eyes of 34 patients with moderate and high myopia who underwent the PR implantation from February to July 2025. Corrected distant visual acuity (CDVA) and anterior chamber depth (ACD) were measured preoperatively. Uncorrected distant visual acuity (UDVA), refractive errors, higher-order aberrations (HOAs), intraocular pressure (IOP), and endothelial cell density (ECD) were measured preoperatively, at 1 week, and at 1 month postoperatively. The central and peripheral vault were measured on the operating day, at 1 week, and at 1 month after surgery.
resultsAt 1 month postoperatively, 95.5% of eyes achieved UDVA equal to or better than the preoperative CDVA. The efficacy index was 1.17 ± 0.19 at 1 month postoperatively. Also, 94.0% of eyes achieved UDVA of 20/20 or better and 94.0% of eyes had residual spherical equivalent (SE) refraction within ± 1.00 D at 1 month postoperatively, demonstrating excellent visual outcomes and refractive predictability. No significant difference in ECD was observed 1 month postoperatively (3118.27 ± 180.95 cells/mm
