Recovery Timeline After Trabeculectomy Ab Externo

Overview of Recovery

Most patients recover their preoperative visual acuity within 1-2 months after trabeculectomy, though the complete recovery period extends to 3 months for full stabilization of intraocular pressure and anterior segment healing 1, 2

A postoperative examination must be performed within 12-36 hours after surgery to evaluate visual acuity, intraocular pressure, and anterior segment status 1, 2
At least one additional follow-up visit should occur during the first 1-2 weeks postoperatively to reassess visual acuity, IOP, and anterior segment findings 1, 2
Additional postoperative visits during a 3-month period are necessary to monitor visual acuity, IOP control, and anterior segment status in uncomplicated cases 1, 2

More frequent follow-up visits are mandatory if complications develop, including flat or shallow anterior chamber 1, 2
More frequent follow-up visits are mandatory if complications develop, including evidence of early bleb failure 1, 2
More frequent follow-up visits are mandatory if complications develop, including increased inflammation 1, 2
More frequent follow-up visits are mandatory if complications develop, including Tenon's cyst or encapsulated bleb formation 1, 2

Topical corticosteroids should be prescribed in the postoperative period and tapered appropriately 1, 2
Periodic examinations are necessary to monitor for corticosteroid-related complications such as elevated IOP 1, 2
