Technique for pediatric corneal crosslinking under general anesthesia

Abstract

Corneal cross-linking (CXL) is typically performed under topical anesthesia, which may be unsuitable in children and individuals with severe anxiety, poor cooperation, or neurodevelopmental issues. We describe a technique of CXL under general anesthesia that uses sevoflurane and propofol with laryngeal airway or nasal oxygen cannulas, and forceps or microsponges to stabilize the eye position intraoperatively. We also developed a simple and time-saving technique of bilateral simultaneous CXL, whereby the second eye can undergo CXL concurrently with the first in a staggered fashion. Using this technique, we have been able to eliminate up to 25% of surgical time required in standard bilateral procedures. Postoperatively, multimodal analgesia was administered to ensure patient comfort and prevent excessive eye rubbing. In total, 21 eyes of 13 subjects ≤18 years of age were treated. During a median follow-up of 14.5 months (range, 4-43), the only complication observed was sterile corneal infiltrate in 1 eye that resolved with a short course of corticosteroids.
