Phacoemulsification and Intraocular Lens Implantation Before, During, or After Canaloplasty in Eyes with Open-Angle Glaucoma

Abstract

Clear corneal phacoemulsification performed before or in combination with canaloplasty is a safe and effective surgical procedure to reduce IOP in adult patients with open-angle glaucoma.

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

“…With regard to complications, hyphaema is a common event after canaloplasty and is suggested as a positive predictor of surgical success as it indicates permeability of the distended trabecular meshwork (Shingleton et al 2008;Lewis et al 2009;Grieshaber et al 2010Grieshaber et al , 2013Ayyala et al 2011;Bull et al 2011;Arthur et al 2013;Matlach et al 2013;Tetz et al 2013). An intracorneal haematoma is rare and can be removed by stab incision (Tetz et al 2013), partial-thickness paracentesis (Gismondi & Brusini 2011) or Nd: YAG laser Descemet membranotomy (Robert & Harasymowycz 2013).…”

“…An intracorneal haematoma is rare and can be removed by stab incision (Tetz et al 2013), partial-thickness paracentesis (Gismondi & Brusini 2011) or Nd: YAG laser Descemet membranotomy (Robert & Harasymowycz 2013). Perforation of the trabeculo-Descemet window during dissection is an intraoperative complication during canaloplasty, which occurs in <10% of all cases (Shingleton et al 2008;Lewis et al 2009;Grieshaber et al 2010;Ayyala et al 2011;Bull et al 2011;Arthur et al 2013;Tetz et al 2013).…”

“…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). …”

“…Tetz and co-workers reported on their 3-year results of canaloplasty in phakic or pseudophakic eyes as well as in combination with cataract surgery. In this study, phacocanaloplasty provided the best IOP reduction with the least need for medication (Tetz et al 2013). Schoenberg et al (2015) reported their outcomes of phacocanaloplasty and phacotrabeculectomy in a retrospective, non-randomized longitudinal cohort study.…”

“…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).…”
