To report intraoperative findings and complications associated with cataract surgery performed after retinal reattachment surgery (RR) via pars plana vitrectomy (PPV) using perfluoro-n-octane (PFO), laser retinopexy, and silicone oil tamponade in dogs.
Retrospective record review of dogs that underwent post-RR cataract surgery. Signalment, time between RR and cataract surgery, type of lens extraction, postoperative visual status, and intra- and postoperative complications were recorded. Cataract formation or progression after RR was categorized as early (≤12 months) or late (>12 months).
A total of 36 dogs (41 eyes) were included. Average time between RR and cataract surgery was 665 days (median: 546). Early postoperative incidence of cataracts occurred in 19 eyes (46.3%). Types of lens extraction included phacoemulsification with intraocular lens (86.1%, 31/36 dogs), phacoemulsification alone (11.1%, 4/36 dogs), and intracapsular lens extraction (2.8%, 1/36 dogs). Visual improvement occurred in 95.1% of eyes (39/41) immediately postoperatively. Long term, 93.9% of eyes (31/33) maintained vision at 1 month, 85.2% of eyes (23/27) at 3 months, 77.3% of eyes (17/22) at 6 months, and 60% (12/20) at 12 months postoperatively. The most common postoperative complications were glaucoma (29.3%, 12/41 eyes), corneal ulceration (24.4%, 10/36 eyes), fibrin formation (21.9%, 9/41 eyes), and silicone oil migration into the anterior chamber (19.5%, 8/41 eyes).
Post-RR cataract surgery should be considered in dogs with vision loss from cataracts after RR. In most eyes, vision was maintained up to 1 year postoperatively.
报告通过经睫状体平坦部玻璃体切除术（PPV）使用全氟辛烷（PFO）、激光视网膜光凝术和硅油填塞进行视网膜复位手术后（RR）行白内障手术的术中发现和相关并发症，这些手术用于治疗犬的白内障。
接受 RR 后白内障手术的犬的回顾性记录审查。记录了品种、RR 与白内障手术之间的时间、晶状体提取的类型、术后视力状态以及术中及术后并发症。RR 后白内障的形成或进展分为早期（≤12 个月）或晚期（>12 个月）。
共纳入 36 只狗（41 只眼）。RR 与白内障手术之间的平均时间为 665 天（中位数：546 天）。19 只眼（46.3%）出现早期术后白内障。晶状体提取的类型包括超声乳化白内障吸除术联合人工晶状体（86.1%，31/36 只狗）、单纯超声乳化白内障吸除术（11.1%，4/36 只狗）和囊内晶状体提取术（2.8%，1/36 只狗）。术后即刻，95.1%（39/41 只眼）的眼视力得到改善。长期随访中，术后 1 个月时，93.9%（31/33 只眼）、术后 3 个月时 85.2%（23/27 只眼）、术后 6 个月时 77.3%（17/22 只眼）、术后 12 个月时 60%（12/20 只眼）保持视力。最常见的术后并发症包括青光眼（29.3%，12/41 只眼）、角膜溃疡（24.4%，10/36 只眼）、纤维蛋白形成（21.9%，9/41 只眼）和硅油向眼前房迁移（19.5%，8/41 只眼）。
RR 后视力丧失的犬应考虑行 RR 后白内障手术。大多数患眼术后 1 年内视力保持稳定。
