Transepithelial photorefractive keratectomy (tPRK) promotes faster re-epithelialization which in turn can reduce the risk of infectious keratitis in the postoperative period. We present a case of a 22-year-old man with infectious keratitis in his left eye 8 days after an uneventful bilateral tPRK. A 2 mm × 5 mm anterior stromal area of corneal infiltration with a same sized overlying epithelial defect was noted at the time of presentation. His uncorrected distance visual acuity was 20/63 in his left eye. Corneal scrapings showed Bordetella bronchiseptica. The infection responded to intensive treatment with topical levofloxacin 0.5% eye drops. The final visual acuity was 20/20 in the left eye.
经上皮准分子激光角膜切削术（tPRK）可促进上皮更快地重新形成，这进而能降低术后感染性角膜炎的风险。我们报告一例22岁男性病例，该患者在双眼tPRK手术顺利完成8天后，左眼发生感染性角膜炎。就诊时发现角膜有一个2毫米×5毫米的前部基质浸润区域，其上方有相同大小的上皮缺损。他左眼的未矫正远视力为20/63。角膜刮片显示有支气管败血博德特氏菌。感染通过局部使用0.5%左氧氟沙星滴眼液进行强化治疗后得到控制。左眼最终视力为20/20。
