Anterior chamber aspirates on completion of extracapsular cataract surgery contain significant numbers of organisms, particularly coagulase negative staphylococci, an important cause of endophthalmitis.
Culture rates were compared in 50 patients after phacoemulsification surgery, which allows the possible benefits of a small, self sealing wound and maintenance of positive intraocular pressure, with a similar number of extracapsular cases.
A culture positive rate of 20% and 24% respectively was found, an insignificant difference.
Small incision surgery has no proved advantage over extracapsular surgery in terms of reducing the intraoperative bacterial inoculum. The significance of this result in terms of causation of endophthalmitis is discussed.
囊外白内障手术完成时前房穿刺液含有大量微生物,尤其是凝固酶阴性葡萄球菌,这是眼内炎的一个重要病因。
对50例接受超声乳化白内障吸除术的患者与数量相近的囊外白内障手术病例的培养率进行比较,超声乳化白内障吸除术具有小的自闭性切口和维持眼内正压的潜在优势。
分别发现培养阳性率为20%和24%,差异无统计学意义。
在减少术中细菌接种方面,小切口手术相对于囊外手术并无已证实的优势。讨论了该结果在眼内炎病因方面的意义。
