To determine wether the cataract extraction method and intraocular lens material affect bacterial contamination of the eye during surgery.
This retrospective study evaluated microbial contamination of the anterior chamber fluid in three group of patients. Group 1: extracapsular extraction and PMMA lens (354 cases). Group 2: phacoemulsification and PMMA lens (474 cases). Group 3: phacoemulsification and silicone lens with PMMA haptic (264 cases).
Microbial contamination rate was in group 1: 5.65%, in group 2: 4.75%, and in group 3: 4.54%. The difference was not statistically significant (chi: 0.321). All contaminants were Gram positive.
Bacterial contamination rate of the anterior chamber is similar during extracapsular extraction and phacoemulsification, and is not modified when using PMMA or silicone lens.
确定白内障摘除方法和人工晶状体材料是否会影响手术期间眼部的细菌污染情况。
这项回顾性研究评估了三组患者前房液中的微生物污染情况。第一组：囊外摘除术及聚甲基丙烯酸甲酯（PMMA）人工晶状体（354例）。第二组：超声乳化术及PMMA人工晶状体（474例）。第三组：超声乳化术及带PMMA襻的硅酮人工晶状体（264例）。
第一组的微生物污染率为5.65%，第二组为4.75%，第三组为4.54%。差异无统计学意义（卡方值：0.321）。所有污染物均为革兰氏阳性菌。
囊外摘除术和超声乳化术期间前房的细菌污染率相似，使用PMMA或硅酮人工晶状体时污染率未改变。
