Trabeculectomy versus canaloplasty (TVC study) in the treatment of patients with open‐angle glaucoma: a prospective randomized clinical trial

“…In line with our results, Ayyala et al (2011) observed a more pronounced IOP reduction after 12 months with fewer medications in trabeculectomy (mean 43%) than canaloplasty (mean 32%). Canaloplasty had a better IOP reduction when performed in combination with cataract surgery (Lewis et al 2007(Lewis et al , 2011Shingleton et al 2008;Bull et al 2011;Arthur et al 2013;Tetz et al 2013). …”

“…Previous studies comparing non-penetrating with penetrating glaucoma surgeries have reported that although canaloplasty may not be as effective as filtering surgery in lowering IOP without medication, complication rate and risk of serious vision-threatening adverse events are low (Ayyala et al 2011;Brusini & Tosoni 2012;Bruggemann et al 2013;Matlach et al 2013). In addition, the combination of canaloplasty with cataract surgery provides a better IOP reduction than single canaloplasty (Lewis et al 2007(Lewis et al , 2011Shingleton et al 2008;Bull et al 2011;Arthur et al 2013;Tetz et al 2013).…”

Combined Cataract-Glaucoma Surgery

“…Combined phaco-canalostomy provides slightly better hypotensive effect and less antiglaucoma drops than canalostomy alone [103,104]. Compared to trabeculectomy it offers lower but not statistically significant hypotensive effect and requires more antiglaucoma medication than trabeculectomy [105].…”

Novel Glaucoma Surgical Devices

“…(Lewis et al, 2011) Three years postoperatively, all study eyes (n = 157) had a mean IOP of 15.2 mm Hg ± 3.5 (SD) and mean glaucoma medication use of 0.8 ± 0.9 compared with a baseline IOP of 23.8 ± 5.0 mm Hg on 1.8 ± 0.9 medications. Eyes with combined cataract-canaloplasty surgery had a mean IOP of 13.6 ± 3.6 mm Hg on 0.3 ± 0.5 medications compared with a baseline IOP of 23.5 ± 5.2 mm Hg on 1.5 ± 1.0 medications.…”
