[Two cases of anterior chamber displacement after XEN gel stent implantation]

Two patients (a 7-year-old female and a 61-year-old male) had poor intraocular pressure control after XEN gel stent implantation. During the process of filtering bleb repair, the XEN gel implant retreated into the anterior chamber, and the limbal and corneal incisions were made. After the implant in the anterior chamber was taken out, it was implanted into the anterior chamber again from the original scleral tunnel for the female patient, while it was re-punctured into the anterior chamber with a 1-ml syringe needle at another site for the male patient. The follow-up examinations at 3 weeks and 6 months after surgery showed good results.
