OBJECTIVE: To evaluate the predictive value of anterior segment optical coherence tomography (AS-OCT) for postoperative corneal edema in cataract patients.
METHODS: A retrospective cohort study of 144 cataract patients from December 2020 to December 2021 was conducted. Patients were divided into edema eyes (84 cases) and observation (60 cases) group based on postoperative corneal edema occurrence. Relevant indicators were compared between groups. Logistic regression identified risk factors for postoperative corneal edema. Receiver operating characteristic curves evaluated the predictive value.
RESULTS: The edema eyes group had significantly higher postoperative central corneal thickness (CCT) and lower postoperative endothelial cell density (ECD) than the observation group (P < 0.05). The edema eyes group also had significantly lower preoperative ECD, anterior chamber depth (ACD), anterior chamber angle (ACA), and preoperative lens position (LP) than the observation group (P < 0.05). Logistic regression analysis showed that preoperative ECD, ACD, ACA, and LP were independent risk factors for postoperative corneal edema (P < 0.05), all of which also showed good predictive value for postoperative corneal edema, with areas under the curve (AUCs) of 0.854, 0.812, 0.791, and 0.778, respectively, under the ROC curve analysis.
CONCLUSION: AS-OCT can provide useful information for predicting postoperative corneal edema in cataract patients. Preoperative ECD, preoperative ACD, preoperative ACA, and preoperative LP are important parameters that can be measured by AS-OCT and used as risk factors for postoperative corneal edema.
