	abstract = {PURPOSE: To explore the association of American Society of Anesthesiologists (ASA) classification with cataract surgery outcomes. SETTING: Five Veterans Affairs Medical Centers, United States. DESIGN: Retrospective observational cohort study. METHODS: The study analyzed the outcomes of cataract surgery cases. Corrected distance visual acuity (CDVA), unanticipated events, and vision-related quality of life (VRQL) were assessed using the National Eye Institute Visual Function Questionnaire (NEI-VFQ), comparing ASA classes I through IV. For some analyses, ASA classes I and II were designated as Group A and ASA classes III and IV were designated Group B. RESULTS: Of the 4923 cases, 875 (17.8\%) were in Group A, 4032 (81.9\%) were in Group B, and 16 (0.3\%) had missing data. The mean CDVA and mean composite NEI-VFQ score improved after cataract surgery in both groups (P\&nbsp;\&lt;\&nbsp;.0001); however, Group A had a better mean postoperative CDVA and postoperative VFQ composite scores than Group B (P\&nbsp;\&lt;\&nbsp;.0001, both outcomes). A higher ASA class was associated with an increased risk for 2 unanticipated events; that is, clinically significant macular edema (CSME) (Group A: 4 [0.47\%] versus Group B: 50 [1.28\%]; adjusted odds ratio [OR], 3.02; 95\% confidence interval [CI], 1.02-13.05; P\&nbsp;=\&nbsp;0.04) and readmission to the hospital within 30\&nbsp;days (2 [0.23\%] versus 56 [1.41\%]; OR, 8.26; 95\% CI, 1.71-148.62; P\&nbsp;=\&nbsp;.004) CONCLUSIONS: Among United States veterans, the ASA classification could be an important predictor of VRQL and visual outcomes. In this cohort, it was associated with an increased risk for 2\&nbsp;serious unanticipated events-CSME and readmission to the hospital-both costly, unwanted outcomes.
