Purpose: To report a case of interface infection by Candida albicans after deep anterior lamellar keratoplasty (DALK).
Methods: A 30-year-old man with keratoconus underwent DALK. Four weeks after surgery, the patient developed multiple infiltrates in the graft-host interface with absence of intraocular infection. Donor rim cultures grew C. albicans. Penetrating keratoplasty (PK) was performed because of worsening of the infection despite topical, local, and systemic antifungal therapy.
Results: Cultures carried out on the excised donor cornea confirmed donor-to-host transmission of C. albicans. An aqueous tap taken before PK was negative. Six months after PK, the corneal graft was clear with no recurrence of infection.
Conclusions: After DALK, in cases of donor graft microbial contamination, infection may develop at the graft-host interface. This may delay or prevent direct intraocular penetration of microorganisms, reducing the risk of development of endophthalmitis. PK may be needed to eradicate the infection in cases where conservative treatment fails.

Amphotericin B eye drops (reconstituted from lyophilized Amphotericin B formulation indicated for intravenous use) is used off-label for fungal keratitis. However, the reconstituted formulation is stable only for a week, even after refrigeration. Moreover, a high dosing frequency makes it an inconvenient treatment practice.

The gut microbiome plays a key role in the pathogenesis and disease activity of inflammatory bowel disease (IBD). While research has focused on the bacterial microbiome, recent studies have shifted towards host genetics and host-fungal interactions. The mycobiota is a vital component of the gastrointestinal microbial community and plays a significant role in immune regulation.
