探讨玻璃体切除术后的白内障超声乳化手术的可行性、临床特点及特殊手术方法。方法 :共 2 1例患者 ( 2 1只眼 )在玻璃体切除手术 7～ 2 7个月后接受超声乳化手术 ,回顾分析其术中操作困难因素、并发症和视力结果。结果 :白内障超声乳化手术后 19只眼视力提高 ,1只眼视力无变化 ,1只眼视力降低。术中几乎在所有病例均可遇到前房深度、瞳孔直径和后囊膜位置骤然变化的情况 ,增加了手术操作的难度。术中 1只眼发生悬韧带离断。术后 18只眼出现轻度狄氏膜皱褶。结论 :虽然在玻璃体切除术后的患者群体施行超声乳化手术操作难度大、易出现并发症 ,但是经谨慎处理后绝大多数患者仍能获得良好的有用视力。
To investigate the feasibility, clinical features and special surgical methods of phacoemulsification after vitrectomy. Methods: A total of 21 patients (21 eyes) underwent phacoemulsification 7 to 27 months after vitrectomy. The intraoperative operative difficulties, complications and visual acuity were retrospectively analyzed. Results: The visual acuity of 19 eyes after phacoemulsification was improved. There was no change of visual acuity in one eye and the visual acuity of one eye was decreased. Surgery in almost all cases can encounter anterior chamber depth, pupil diameter and posterior capsule position abrupt changes in the situation, increasing the difficulty of surgical operations. An eye surgery occurred suspensory ligament rupture. Eighteen eyes had mild Dirichlet folds after operation. CONCLUSIONS: Although phacoemulsification is difficult and prone to complications in a population of patients after vitrectomy, the majority of patients after cautious treatment still have good useful visual acuity.
