Early Postoperative Therapeutic Scleral Lens Intervention for Penetrating Keratoplasty Complications in Atopic Keratoconjunctivitis.

A 52-year-old white man with keratoconus and severe atopic keratoconjunctivitis underwent penetrating keratoplasty (PK) for visual rehabilitation in the left eye. Post-PK complications included a persistent epithelial defect. Therapeutic scleral lens wear was initiated 2 weeks post-PK. Customizations were incorporated into the lens design to prevent suction and corneal hypoxia during lens wear. Post-PK herpes epithelial keratitis developed shortly thereafter, causing recurrence of a nonhealing epithelial defect. The patient was treated with oral antiviral therapy, discontinuation of dupilumab, and daily waking-hour scleral lens wear, which was used as an antibiotic drug delivery device. The cornea fully epithelialized, and best-corrected visual acuity improved to 20/40-2. The patient continued with daily waking-hour scleral lens wear and was without recurrence of persistent epithelial defect or herpes keratitis at 18 months. No scleral lens-related complications were observed despite the unconventional early intervention with a therapeutic scleral lens.
