Herpes simplex keratitis following Smart Pulse Technology assisted transepithelial photorefractive keratectomy: a case report

Abstract

Abstract Background Herpes simplex keratitis (HSK) is a rare and sight-threatening complication following refractive surgery. SmartSurfACE surgery is the result of combining transepithelial photorefractive keratectomy (trans-PRK) with Smart Pulse Technology (SPT) to diminish surface irregularities of the residual stromal bed after surgery with less pain, faster re-epithelialization, and better postoperative visual acuity. In this article, we report the first case of HSK following SmartSurf ACE without history of herpetic eye disease. Case presentation A 21-year-old woman underwent bilateral SmartSurfACE without history of clinical herpetic infection, active eye disease, or systemic disease. Mild superficial punctate keratitis occurred on the tenth postoperative day. The condition was not improved by ophthalmic drugs of anti-inflammation or epithelial healings. Dendritic corneal ulcer appeared within one month, which is the commonly recognized clinical manifestation of herpes simplex keratitis. The patient was managed with topical and systemic antiviral agents. After nine days of antiviral therapy, the lesion healed up, remaining mild stromal scarring in both eyes ultimately. Conclusion Herpes simplex keratitis is a rare but sight-threatening complication following refractive surgery. For the ocular irritation symptoms of postoperative patients, we should consider the possibility of HSK and give timely treatment.
