To identify risk factors and perioperative complications and assess postoperative visual outcome in patients of white mature cataracts undergoing phacoemulsification surgery.
This cross-sectional study was conducted on 46 patients of white mature cataract undergoing phacoemulsification. Preoperatively, a detailed ocular examination was done, and anterior chamber depth (ACD) and lens thickness (LT) were measured on ultrasound biomicroscopy. Intraoperative and postoperative complications (on days 1, 7, and 30) and best-corrected visual acuity on postoperative day 30 were noted.
The mean age of patients was 60.78 ± 9.001 years. The study group consisted of 41.3% of males and 58.7% of females. 8 (19.56%) cases encountered complications during phacoemulsification surgery. The intraoperative complications were capsulorhexis-related in 5 (10.86%) patients, posterior capsular rent in 2 (4.3%) patients, and 1 (2.17%) case had zonular dialysis. There was no difference in mean ACD and LT in cases who developed complications and those who underwent uneventful surgery ( > 0.05). The commonly observed postoperative complications on day 1 were corneal edema (41.3%), anterior chamber flare (45.65%), and cells (39.13%) which resolved with routine topical medications. All patients showed a significant reduction in postoperative intraocular pressure ( < 0.001). A total of 37 (80.43%) eyes regained vision between 6/6 and 6/9 postoperatively ( < 0.001).
Phacoemulsification surgery is safe in white mature cataract that results in significant visual improvement. Common intraoperative complications are capsule related, while frequently encountered postoperative complications are corneal edema and anterior chamber reaction. Preoperative ACD and LT have no role in predicting intraoperative complications.
分析并评估行超声乳化白内障吸除术的白人成熟性白内障患者的危险因素、围手术期并发症及术后视力结果。
这是一项横断面研究，共纳入 46 例行超声乳化白内障吸除术的白人成熟性白内障患者。术前详细眼部检查，超声生物显微镜测量前房深度（ACD）和晶状体厚度（LT）。记录术中及术后（第 1、7、30 天）并发症和术后第 30 天最佳矫正视力。
患者平均年龄为 60.78±9.001 岁，男性占 41.3%，女性占 58.7%。8 例（19.56%）患者在超声乳化白内障吸除术中发生并发症。术中并发症包括 5 例（10.86%）撕囊相关并发症、2 例（4.3%）后囊膜破裂和 1 例（2.17%）悬韧带离断。发生并发症和未发生并发症的患者平均 ACD 和 LT 差异无统计学意义（>0.05）。术后第 1 天最常见的并发症是角膜水肿（41.3%）、前房闪辉（45.65%）和细胞（39.13%），均经常规局部药物治疗缓解。所有患者术后眼压均显著降低（<0.001）。术后共有 37 只眼（80.43%）视力恢复至 6/6 至 6/9（<0.001）。
超声乳化白内障吸除术治疗白人成熟性白内障安全有效，可显著改善视力。常见的术中并发症与晶状体囊袋相关，常见的术后并发症为角膜水肿和前房反应。术前 ACD 和 LT 对预测术中并发症无作用。
