OBJECTIVE: To analyze trends in bilateral, same-day laser iridotomies, and trabeculoplasties in Ontario over the last decade. METHODS: Ontario Health Insurance Plan billing service claims between 2000 and 2013 were analyzed for the yearly number of glaucoma laser procedures. The annual number of Ontarians with primary open-angle glaucoma (POAG) was estimated by applying composite prevalence curves to published population data and the yearly number of procedures per 1000 Ontarians with POAG was calculated. RESULTS: The volume of same-day bilateral trabeculoplasties increased from 15.3 per 1000 with POAG in 2000 to 74.7 in 2013 (4.9-fold). The proportion that were same-day bilateral procedures increased from 22.7% in 2000 to 40.2% in 2004 (76.9% increase) and remained stable from 2009 to 2013, reaching 38.5% in 2013. The number of same-day bilateral laser iridotomies increased from 3126 in 2000 to 11,716 in 2013 (3.75-fold). The proportion of iridotomies that were bilateral increased from 39% in 2000 to 54.6% in 2006 (40% increase) and remained stable from 2006 to 2013, reaching 56.7% in 2013. CONCLUSIONS: The increase in same-day bilateral trabeculoplasties coincided with the introduction of selective laser trabeculoplasty. The proportion of this practice remained constant for the last 3 years of the study period. In 2013, 56.7% of iridotomies and 38.5% of trabeculoplasties were performed as same-day bilateral procedures. We recommend comparison studies between same-day and sequential laser therapies to assess complication rates and patient satisfaction to provide an evidence-based treatment approach, as there are limited data to support this practice.
