目的:评价表面麻醉下白内障囊外摘除术并后房型人工晶体植入术的疗效及其可行性。方法:在扶贫复明行动中,随机选择性地对87例92只眼行表面麻醉下白内障囊外摘除术并后房型人工晶体植入术。结果:满意率达90.2%(83只眼),有效率达96.7％(89只眼)。后囊膜破损玻璃体丢失率3.3%(3只眼),术中追加球后麻醉,方完成手术。后囊膜破损玻璃体丢失率比同期球周麻醉后囊膜破损玻璃体丢失率还低,这可能与我们初次把表面麻醉用于白内障囊外摘除术,病例选择谨慎有关。结论:表面麻醉下白内障囊外摘除术并后房型人工晶体植入术,是一种安全有效且简便易行的麻醉方法。
Objective: To evaluate the efficacy and feasibility of extracapsular cataract extraction with posterior chamber intraocular lens implantation under surface anesthesia. Methods: Eighty - seven eyes (87 eyes) underwent selective epidural cataract extraction and posterior chamber intraocular lens implantation under surface anesthesia. Results: The satisfaction rate was 90.2% (83 eyes) and the effective rate was 96.7% (89 eyes). Posterior capsule loss of vitreous body loss rate of 3.3% (3 eyes), intraoperative additional ball after anesthesia, to complete the operation. The rate of vitreous loss after posterior capsular rupture was lower than the rate of vitreous loss after capsulotomy at the same period of the same period, which may be related to our initial application of topical anesthesia for extracapsular cataract extraction and caution in case selection. Conclusion: Extracapsular cataract extraction with posterior chamber intraocular lens implantation under surface anesthesia is a safe, effective and simple method of anesthesia.
