Postoperative contact lens-associated yeast keratitis after pterygium excision: Clinical insights Notes: The use of contact lenses following pterygium surgery is common for protecting the ocular surface and promoting healing. However, this practice can predispose patients to infections, including fungal keratitis. This case report details the occurrence of yeast-induced keratitis in a 53-year-old man following pterygium excision and contact lens application. He presented with redness, pain, and blurred vision in his left eye 2 weeks after pterygium surgery. A therapeutic contact lens had been applied postoperatively. Clinical examination revealed conjunctival hyperemia and a corneal infiltrate suggestive of keratitis. Diagnostic testing, including a potassium hydroxide (KOH) preparation, confirmed the presence of yeast cells. The patient was immediately started on topical antifungal therapy, including natamycin drops, and the contact lens was removed. This case underscores the importance of early recognition and aggressive treatment of fungal keratitis. Preventive strategies and strict postoperative follow-up are essential to mitigate the risks associated with contact lens use after ocular procedures.
