Präoperatives Management bei subkonjunktivalen/subtenonalen glaukomchirurgischen Operationen unter besonderer Berücksichtigung des Gelimplantats (XEN®)

BACKGROUND: When using subconjunctival/sub-Tenon's ab interno glaucoma surgical procedures, patient selection and preoperative management are essential to reduce postoperative scarring of the bleb. OBJECTIVE: The aim of this study was to compile a list of risk factors that may have an unfavorable effect on the scarring process. METHOD: A literature search was carried out in PubMed with respect to the scarring process of the gel implant XEN®. RESULTS: Ophthalmological risk factors for conjunctivoscleral/Tenon's wound healing process include dry eye, allergies, use of eye drops containing preservatives and previous eye surgery. CONCLUSION: The preoperative administration of artificial tear substitutes, corticosteroids and the fundamental change to preservative-free eye drops can support the normalization of a chronic inflammatory altered conjunctiva and thus positively influence the wound healing process after surgery.
