Analysis of Risk Factors of Postoperative Dry Eye in Cataract Patients Based on Lens Nucleus Hardness Grading.

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
Objective: To investigate the risk factors associated with dry eye disease (DED) development in cataract (CAT) patients following phacoemulsification surgery, with a focus on lens nucleus hardness grading, and to develop a predictive model for individualized clinical management. Methods: This retrospective study included 150 cataract patients who underwent phacoemulsification from January 2023 to January 2025. Lens nucleus hardness was graded using the Emery system. Preoperative assessments included ocular surface status and systemic comorbidities. Logistic regression was used to identify independent risk factors, and a predictive model was developed and evaluated by receiver operating characteristic (ROC) analysis. Results: Postoperative DED occurred in 38.7% of patients. Multivariate analysis revealed that diabetes mellitus, history of keratoconjunctivitis, conjunctivochalasis grade ≥III, lens nucleus hardness grade ≥IV, and 3.0 mm clear limbal incision were independent risk factors (all P<0.05). The prediction model showed good performance (AUC=0.836), with 84.5% sensitivity and 69.6% specificity. Conclusion: Lens nucleus hardness, along with key clinical factors, independently predicts DED risk after cataract surgery. The developed model may assist in early risk identification and personalized perioperative management.
