Corneal staining during cataract surgery: Natural course, ASOCT features, and preventive measures

Abstract

We report the natural course of the accidental injection of trypan blue into the corneal stroma while performing a routine cataract surgery by a resident during a training session. The corneal staining resolved with conservative medical treatment over 7 weeks. This case describes the anterior segment optical coherence tomography (ASOCT) features of corneal staining. It emphasizes on the relatively benign nature of this dye and the follow-up course. Causes that may be responsible for this untoward complication are highlighted with the necessary preventive measures that need to be taken care are also discussed.
