Detailed description
Unicentric, non-randomized, single arm safety and performance study which will be conducted in accordance with the applicable parts of CFR 21 and Standard EN-ISO 14155 I & II: 2003 on clinical investigations with medical devices on human subjects and recommendations guiding physicians in biomedical research involving human subjects adopted by the 18th World Medical Assembly, Helsinki, Finland, 1964 and later revisions
Interventions
Insertion of MIDI Arrow subconjunctivally with a fornix-based incision after pretreatment of scleral surface with 0.4 mg/mL MMC and insertion of MIDI Arrow tube through sclera into anterior chamber of eye
