Defining a Cataract Surgery Protocol in Diabetic Patients: A Pilot Study.

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
Purpose: Cataract surgery in patients with Type II diabetes mellitus (T2DM) can lead to complications. A well-defined surgical protocol that optimizes the procedure and applies strict selection criteria may reduce the risk of adverse outcomes. We evaluate safety and efficacy outcomes in diabetic patients undergoing cataract surgery by employing a specific protocol for preoperative evaluation and surgery selection. Methods: A prospective, non-randomized pilot study was performed on patients with T2DM and visually significant cataract. Patients adhered to a strict preoperative selection protocol including classification as per Diabetic Retinopathy Severity Scale (DRSS), stable ocular coherence tomography, and anti-VEGF treatment-naive for a minimum 3 months before surgery. Patients underwent phacoemulsification surgery with monofocal intraocular lens implantation (IOL) without intra-operative corticosteroid or anti-VEGF injection and undertook the same post-operative regimen. Final patient evaluation was performed at 3 months to evaluate vision, refractive and safety outcomes. Results: At 3 months (n=25 eyes), the visual acuity efficacy index was 1.32. The incidence of clinical CME was 16%. An increase from baseline CMT of 1 micron to 25 microns was seen in 53% of eyes with an increase between 26 microns to 50 microns seen in 20% of eyes. A recurrence or new onset of DME was diagnosed in 8.0% of eyes. Factors found to increase the recurrence of DME included higher DRSS at baseline (p=0.032) and previous treatment with anti-VEGF (p<0.001). Conclusion: Patient selection with adherence to a robust preoperative protocol can result in excellent visual outcomes and manageable complication rates.
