A 4-year-old male Canada lynx was referred to the ophthalmology service at the University of Saskatchewan with a 7-month history of cataract and chronic phacoclastic uveitis secondary to penetrating trauma from a lynx claw. Ophthalmic examination of the right eye revealed a corneal scar, marked aqueous flare, extensive fibrovascular membranes extending from the iris to the lens, anterior and posterior synechiae, immature cataract, and anterior vitritis; the fundus was not visible. Phacoemulsification surgery and intraocular lens implantation using a custom lens of D+46 and 14 mm (An-vision, West Jordan, Utah, USA) was performed. Post-operative medications included sub-conjunctival injections of atropine, cefazolin, and triamcinolone, and oral doxycycline and prednisolone. At the 5-month follow-up, the uveitis was controlled, and a normal fundus was visualized; at 21 mo, the eye remained comfortable and visual. This is the first case report to describe phacoemulsification in a wild felid as a treatment for a traumatic cataract and severe phacoclastic uveitis. Key clinical message: Despite chronic phacoclastic uveitis, phacoemulsification surgery can provide a positive outcome for mature wild felids with traumatic lens rupture, even when topical treatment cannot be administered.
一只 4 岁雄性加拿大猞猁因被猞猁爪子穿透性创伤而导致白内障和慢性白内障溶解性葡萄膜炎，病程已有 7 个月，被转诊至萨斯喀彻温大学眼科服务中心。右眼检查发现角膜瘢痕、明显的房水闪辉、从虹膜延伸到晶状体的广泛纤维血管膜、前后粘连、未成熟白内障和前葡萄膜炎；眼底无法看见。施行白内障超声乳化手术和使用美国犹他州西约旦市 An-vision 公司的 D+46 和 14 毫米定制晶状体的人工晶状体植入术。术后用药包括球结膜下注射阿托品、头孢唑林和曲安奈德，以及口服强力霉素和泼尼松龙。术后 5 个月时，葡萄膜炎得到控制，眼底可见正常；术后 21 个月时，眼睛仍然舒适且有视力。这是首例描述对野生动物行白内障超声乳化术治疗外伤性白内障和严重白内障溶解性葡萄膜炎的病例报告。主要临床信息：尽管存在慢性白内障溶解性葡萄膜炎，但即使无法进行局部治疗，白内障超声乳化手术也可为外伤性晶状体破裂的成熟野生猫科动物带来积极的结果。
