To observe the posterior continuous curvilinear capsulorhexis (PCCC) after cataract surgery in control eyes and eyes with an increased risk for postoperative inflammation.
Department of Ophthalmology, University Hospital Antwerp, Belgium.
After phacoemulsification, a PCCC was performed before intraocular lens (IOL) implantation in 20 eyes of 18 patients with ocular or systemic conditions that predisposed them for increased postoperative inflammation; e.g., diabetes, uveitis, retinitis pigmentosa (inflammation group). These eyes were compared with 20 eyes of 16 patients who had the same surgical procedure but did not present a history of medical or ocular pathology (control group). The postoperative follow-up was 6 months to 3 years. Reclosure of the PCCC was evaluated by anterior segment photographs. The reclosure was classified as partial when newly formed tissue was present at the PCCC margin and total when the proliferation covered the entire PCCC area.
Three types of PCCC reclosure were found: fibrotic, Elschnig pearl or multilayer, and monolayer. All 3 were seen within or at the margin of the PCCC area. Reclosure (total and partial) occurred in 8 eyes (40%) in the control group and 10 (50%) in the inflammation group. Total reclosure was more frequent in the inflammation group (4 eyes [20%]) than in the control group (1 eye [5%]). Monolayered or multilayered cellular proliferation was present in 8 eyes (40%) in the control group and 4 eyes (20%) in the inflammation group; fibrotic proliferation was found in the inflammation group only (7 eyes [35%]).
Reclosure of the PCCC occurred in both groups, although the frequency of reclosure was slightly higher in the inflammation group. Although PCCC does not prevent posterior capsule opacification in all cases, it is useful in specific situations.
观察白内障手术后对照组以及术后炎症风险增加的眼中的后囊连续环形撕囊术（PCCC）情况。
比利时安特卫普大学医院眼科。
在18例患有眼部或全身疾病、术后炎症风险增加的患者（如糖尿病、葡萄膜炎、色素性视网膜炎）（炎症组）的20只眼中，在超声乳化术后人工晶状体（IOL）植入前进行了PCCC。将这些眼与16例接受相同手术但无内科或眼科病史的患者的20只眼（对照组）进行比较。术后随访6个月至3年。通过眼前节照片评估PCCC的再闭合情况。当PCCC边缘出现新形成的组织时，再闭合被分类为部分性，当增殖覆盖整个PCCC区域时则为完全性。
发现了三种类型的PCCC再闭合：纤维化型、Elschnig珠或多层型以及单层型。所有三种类型均见于PCCC区域内或边缘。对照组8只眼（40%）和炎症组10只眼（50%）发生了再闭合（完全性和部分性）。炎症组完全再闭合（4只眼[20%]）比对照组（1只眼[5%]）更常见。对照组8只眼（40%）和炎症组4只眼（20%）出现单层或多层细胞增殖；仅在炎症组发现纤维化增殖（7只眼[35%]）。
两组均发生了PCCC再闭合，尽管炎症组再闭合的频率略高。虽然PCCC并非在所有情况下都能预防后囊混浊，但在特定情况下是有用的。
