PURPOSE
To report a case of rapidly progressive infectious keratitis after INTACS implantation for keratoconus.
METHODS
A 32-year-old man presented with pain and decreased vision in the right eye of 2 days' duration. Right eye visual acuity was 20/800. He had undergone bilateral INTACS implantation 40 days prior for treatment of keratoconus.
RESULTS
Slit-lamp examination revealed corneal ulceration and loose suture. The corneal ulcer progressed despite aggressive therapy, and the patient underwent penetrating keratoplasty 48 hours after admission. The culture from corneal scraping and corneal button was positive for Staphylococcus aureus.
CONCLUSIONS
Infectious keratitis is a rare but devastating complication of INTACS implantation for treatment of keratoconus. Meticulous wound closure is necessary to reduce the risk of infection, especially in eyes with irregular corneal contour and variable corneal thickness.
目的
报告1例圆锥角膜患者行角膜基质环植入术（INTACS）后发生快速进展性感染性角膜炎的病例。
方法
一名32岁男性，右眼疼痛、视力下降2天。右眼视力为20/800。他在40天前因圆锥角膜接受了双眼INTACS植入术。
结果
裂隙灯检查发现角膜溃疡和缝线松动。尽管积极治疗，角膜溃疡仍进展，患者入院48小时后接受了穿透性角膜移植术。角膜刮片和角膜植片的培养结果显示金黄色葡萄球菌阳性。
结论
感染性角膜炎是圆锥角膜INTACS植入术罕见但具有破坏性的并发症。精细的伤口闭合对于降低感染风险很有必要，尤其是对于角膜轮廓不规则和角膜厚度可变的眼睛。
