After medical stabilization of IOP and inflammation, all patients underwent cataract surgery within 1 month of the acute attack. Anterior segment parameters were assessed using Scheimpflug-Placido disc tomography before and 1 month after surgery. Paired t-tests were used for statistical analysis.Results: The mean age of patients was 65.76 \u00b1 9.63 years. Postoperatively, best-corrected visual acuity improved significantly (preoperative, 0.81 \u00b1 0.92 logMAR; postoperative, 0.18 \u00b1 0.30 logMAR; p &lt; 0.01). Mean IOP decreased by 22.80 \u00b1 3.45 mmHg (p &lt; 0.01). Significant increases were observed in iridocorneal angle (from 24.62\u00b0 \u00b1 9.59\u00b0 to 46.20\u00b0 \u00b1 10.93\u00b0), anterior chamber depth (from 1.34 \u00b1 0.65 to 3.02 \u00b1 0.82 mm), and anterior chamber volume (from 98.01 \u00b1 28.62 to 145.87 \u00b1 27.27 mm3), all with p &lt; 0.01. Central corneal thickness decreased slightly but significantly (from 579.80 \u00b1 47.48 to 556.80 \u00b1 47.29 \u03bcm, p = 0.03).Conclusions: Early lens extraction in AACG significantly improves anterior segment parameters and lowers IOP. Scheimpflug- Placido disc tomography is a useful noninvasive tool to quantify these changes.<\/jats:p>","DOI":"10.3341\/kjo.2025.0069","type":"journal-article","created":{"date-parts":[[2026,2,23]],"date-time":"2026-02-23T06:27:17Z","timestamp":1771828037000},"page":"274-279","update-policy":"https:\/\/doi.org\/10.3341\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Anterior
