PURPOSE
To determine whether vitrectomy instrumentation improved outcomes when vitreous loss occurred during either extracapsular cataract extraction (ECCE) or phacoemulsification (PE) with posterior chamber lens implantation (PCIOL).
METHODS
A consecutive series of ECCE + PCIOL (group 1: 1985-1989) and PE + PCIOL (group 2: 1993-1997) surgeries by a single surgeon was reviewed retrospectively.
RESULTS
In group 1, 14 of 647 patients (2.2%) and in group 2, 9 of 665 patients (1.4%) experienced vitreous loss. In group 1, final visual acuity averaged 20/83; in group 2, 20/25 (P = .005). Average follow-up was 5.7 years (group 1) and 3.2 years (group 2). Uveitis, glaucoma, corneal problems, and retinal problems were assessed.
CONCLUSIONS
Anterior vitrectomy reduced complications from vitreous loss. Fewer vitreous losses occurred with PE than ECCE. Patients with vitreous loss after PE attained better vision.
目的
确定在白内障囊外摘除术（ECCE）或超声乳化白内障吸除术（PE）联合后房型人工晶状体植入术（PCIOL）过程中发生玻璃体脱出时，玻璃体切割器械是否能改善手术效果。
方法
回顾性分析由同一位外科医生连续进行的ECCE + PCIOL手术（第1组：1985 - 1989年）和PE + PCIOL手术（第2组：1993 - 1997年）。
结果
第1组647例患者中有14例（2.2%）发生玻璃体脱出，第2组665例患者中有9例（1.4%）发生玻璃体脱出。第1组最终视力平均为20/83；第2组为20/25（P = 0.005）。第1组平均随访5.7年，第2组平均随访3.2年。对葡萄膜炎、青光眼、角膜问题和视网膜问题进行了评估。
结论
前部玻璃体切割术可减少玻璃体脱出引起的并发症。PE手术中发生玻璃体脱出的情况少于ECCE。PE术后发生玻璃体脱出的患者视力恢复更好。
