The outcome label was the procedure actually selected and performed by clinicians, including ICL, SMILE, LASIK, and SURFACE. Forty-eight structured preoperative features were analyzed, including demographic, refractive, visual, ocular-surface, tomographic, pachymetric, anterior-segment, Pentacam-derived deviation/risk, and Corvis ST-derived variables.

Baseline clinical and imaging characteristics were compared between fibrosis and non-fibrosis groups. Univariate and multivariable logistic regression analyses were performed to identify factors associated with 1-year fibrosis, and receiver operating characteristic (ROC) curves were used to assess predictive performance.</p><p><strong>Results: </strong>A total of 72 patients (88 eyes) were included, of which 31 eyes developed fibrosis at 1 year and 57 did not. Compared with the non-fibrosis group, eyes that developed fibrosis had worse baseline best-corrected visual acuity (BCVA), greater baseline central macular thickness (CMT), and a higher prevalence of subretinal hyperreflective material (SHRM), retinal hemorrhage, type 2/mixed MNV, high pigment epithelial detachment, and intraretinal fluid. At baseline, the fibrosis group showed significantly higher MNV vessel density, whereas MNV fractal dimension showed a borderline difference. At the post-loading visit, MNV fractal dimension, MNV branch points, MNV endpoints, MNV segments, and MNV vessel density were all significantly higher in the fibrosis group. However, within-group comparisons between baseline and the post-loading visit revealed no significant changes in OCTA parameters in either group. In multivariable analysis, baseline BCVA (OR 1.162, 95% CI 1.024-1.319; P = 0.020), baseline CMT (OR 1.032, 95% CI 1.001-1.064; P = 0.043), and baseline MNV vessel density (OR 1.073, 95% CI 1.009-1.142; P = 0.025) remained independently associated with 1-year fibrosis, whereas SHRM did not. The combined model achieved the best predictive performance, with an area under the ROC curve of 0.787 (95% CI 0.688-0.874).</p><p><strong>Conclusions: </strong>Eyes with treatment-naïve nAMD that developed fibrosis within 1 year had worse baseline disease status and distinct OCTA microvascular characteristics. Baseline BCVA, baseline CMT, and baseline MNV vessel density were independently associated with fibrosis.
