Long-term Results of Nd:YAG Goniopuncture on Viscocanalostomy and Phacoviscocanalostomy

Précis: Laser goniopuncture (LGP) is an effective outpatient procedure which has been shown to maintain reduced intraocular pressure (IOP) 5 years following initial laser treatment in patients who have had viscocanalostomy (VC) (with or without phacoemulsification). Purpose: The purpose of this study was to establish the long term (5 y) efficacy of neodymium-doped:yttrium aluminum-garnet LGP to lower IOP following VC or phacoviscocanalostomy (PVC) in patients with glaucoma. Patients and Methods: This retrospective study analyzed patients who underwent LGP following VC±phacoemulsification between 2009 and 2012 at the Stanley Eye Unit in Abergele. Reason for further intervention included either increasing IOP outside target range or worsening visual fields. Statistical analyses were performed comparing pregoniopucture values to those taken up to 5 years later. Results: Of the 620 VC and PVC procedures performed between 2009 and 2012, 218 eyes underwent LGP after a mean of 25 months [95% confidence interval (CI): 22.58 to 27.41] following surgery. Patients having a PVC had a longer mean time to goniopuncture compared with those who were phakic and had VC only (P
