Complications after XEN glaucoma gel microstent implantation in a postoperative period of 4 years
| Postoperative complications | N = 64 | |
|---|---|---|
| n | % | |
| Secondary surgical procedure (unrelated; ex: Nd:YAG capsulotomy due to secondary cataract) | 2 | 3 |
| Secondary surgical procedure (related to XEN) due to high IOP | ||
| Selective laser trabeculoplasty | 1 | 2 |
| Filtering glaucoma surgeries (trabeculectomy n = 10, Bearveldt glaucoma implant n = 1, Ahmed valve n = 1) | 12 | 19 |
| Cyclodestructive procedures | 3 | 5 |
| Secondary surgical procedure (related to XEN) due to hypotony (defined as: Choroidal effusion, shallow anterior chamber, hypotony maculopathy) | ||
| Anterior chamber refill† | 3 | 5 |
| Exposure of the XEN implant‡ (and additional filtering glaucoma surgery) | 1 | 2 |
| Inner obstruction of the implant—Resolved with Nd:YAG laser | 2 | 3 |
| Cataract operation due to cataract progression | 7 | 11 |
| Loss of light perception | 0 | 0 |
| Lost of follow‐up | 11 | 17 |
†
In one patient an explantation of the XEN implant was necessary because of persistent hypotony.
‡
In one patient bleb revision was required due to exposure of the XEN implant and further filtering glaucoma surgery was necessary; intraocular pressure (IOP).
