Objective:
To assess the safety and effectiveness of phacoemulsification combined with XEN45 implant surgery in patients with cataract and open-angle glaucoma, with 12-month follow-up.
Methods:
A prospective study conducted on 30 eyes requiring phacoemulsification with, at least, 2 medications to control intraocular pressure (IOP). Phacoemulsification combined with XEN45 implant surgery was performed within 15minutes of administering subconjunctival mitomycin C. Surgery was performed through 2 temporal incisions, separated by 90°, using the inferior to enter the XEN45 and to implant it in the superior nasal region. A record was made of the best corrected visual acuity, IOP before and 1 day, 1 month, 3 months, 6 months, 9 months, and 12 months after surgery, the number of antiglaucomatous medications, and complications.
Results:
The best corrected visual acuity was 0.37±0.2 and 0.72±0.15 before and 12 months after surgery, respectively. The pre-operative IOP was 21.2±3.4mmHg, with 3.07 drugs, decreasing by 61.65% on the first day, 37.26% at 1 month, 35.05% at 3 months, 31% at 6 months, 30.6% at 9 months, and 29.34% at 12 months. The number of medications decreased by 94.57%. Complications occurred in 3 eyes, 2 of them were excluded because we could not complete the implantation (280° subconjunctival haemorrhage and XEN extrusion when trying to reposition). In a third case, the bleb was encapsulated at 5 months after surgery.
Conclusions:
The phacoemulsification combined with XEN45 implant surgery can effectively reduce IOP and the number of drugs in mild-moderate open-angle glaucoma, as they rehabilitate the VA. The use of only 2 micro-invasive incisions makes it simple, quick and safe, with few complications at 12 months follow-up from surgery.
