Brief Summary

Purpose: To report the follow-up data for patients who had XEN45 gel stent implantation, a new method of minimally invasive glaucoma surgery (MIGS). Material and Methods: Fifteen eyes of fifteen patients who had XEN45 gel stent implantation surgery were investigated in the study. All the patients were examined preoperatively and at the following postoperative time points: 1 day; 1 and 2 weeks; and 1, 2, 3, 6, and 12 months. Intraocular pressure (IOP) was measured by Goldmann applanation tonometry. Combined surgical procedures (XEN 45 + phacoemulsification + intraocular lens) were performed in the cases that had cataracts in addition to glaucoma.

Conditions

Glaucoma Eye

Keywords

glaucoma; trabeculectomy; minimally invasive glaucoma surgery; XEN45 gel stent

Outcome Measures

Primary Outcomes (1)

• Intraocular pressure

  Mean intraocular pressure values

  Postoperative 12 months

Secondary Outcomes (2)

• Antiglaucomatous medications

  Postoperative 12 months

• Incidence of complications

  Postoperative 12 months

Interventions

XEN45 gel stent implantation in glaucoma surgery DEVICE

The XEN gel stent (Allergan, Dublin, Ireland) is a recently developed, permanent, ab interno collagen implant that reduces IOP by draining aqueous fluid from the anterior chamber into the subconjunctival space

Eligibility Criteria

• Age: 18 Years - 80 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Probability Sample

Study Population

Fifteen patients who had an XEN45 gel stent implantation surgery between January 2015 and March 2016 were enrolled in the study.

You may qualify if:

• Primary open-angle glaucoma, pseudoexfoliative glaucoma, or pigmentary glaucoma, with uncontrolled IOP and progressive visual field damage despite using the maximum tolerated dose of topical antiglaucomatous medications. Patients who had previous glaucoma surgery were included as well.
