PRCIS: The PAUL Glaucoma Implant is an effective intraocular pressure (IOP)-lowering device with an acceptable safety profile. Its design as a nonvalved device with a small tube diameter using a vicryl ligation suture around the tube that is posteriorly reabsorbed instead of an ab luminal stent makes it an option in cases selected for glaucoma drainage device implantation. PURPOSE: The aim was to determine the 1-year efficacy and safety of PAUL Glaucoma Implant using a uniform, standardized surgical procedure. MATERIALS AND METHODS: Retrospective, cohort study. Patient charts were screened between December 2018 and January 2020, with inclusion requiring a minimum follow-up of 12 months. Primary outcome was IOP-lowering at 12 months, with surgical success defined as ≤18 mm Hg and at least 30% reduction and higher than 5 mm Hg. Absolute success was achieved if no IOP-lowering medication was needed and qualified success if otherwise. Safety outcomes were also analyzed. A standardized protocol was followed in all cases, which included mitomycin C application and 1 vicryl ligation of the tube. RESULTS: A total of 24 eyes from 21 patients fulfilled inclusion criteria. Median patient age at time of surgery was 42 years (range: 1 to 76 y). IOP decreased from 31.4 (10.0) mm Hg in preoperative period to 12.5 (4.3) mm Hg in the last follow-up (P<0.001). Qualified success criteria were fulfilled by 75% of cases, while absolute success was 33%. The mean number of IOP-lowering drugs used before surgery was 3.0 and 0.9 at the 12-month visit (P<0.001). No postoperative hypotony requiring intervention was recorded. CONCLUSIONS: PAUL Glaucoma Implant appears to be a safe and effective glaucoma drainage implant for the treatment of moderate and advanced glaucoma.
