AIM: To present a case of double anterior chamber after DALK and its surgical management.
CASE DESCRIPTION: A 67-year-old healthy woman underwent deep anterior lamellar keratoplasty (DALK) in her right eye for keratoconus with the big-bubble technique. About 7 days after surgery a partial detachment of the Descemet membrane from the posterior corneal stroma was revealed using AS-OCT (double anterior chamber appearance). In spite of two injections in the anterior chamber of air and gas on the 7th and 9th post-operative days respectively, the double anterior chamber still persisted. Furthermore, both air and gas passed through the little perforation of the host Descemet membrane-endothelium complex and enlarged the space between the stroma and Descemet membrane. About 10 weeks after DALK, a spontaneous resolution of the double anterior chamber was observed.
CONCLUSION: This case suggests that an injection of air or gas into the anterior chamber, to deal with a Descemet membrane detachment following perforation during DALK procedure, can enlarge the double anterior chamber by increasing the space between stroma and Descemet membrane. These cases can be managed with a "wait and see" strategy for a spontaneous resolution to Descemet membrane detachment.
