Barplot of ciliary body ablation procedures over time. External and endoscopic were not distinguished before 2005. The data from 1994 to 2011 were derived from a universe of Medicare claims data and the values from 2012-2017 from both Medicare claims and the CMS payment data to individual physicians. The era of a new code for endoscopic ciliary ablation is indicated by the highlighted background starting in 2005 and the introduction of the new external laser and probe is indicated by the highlighted background starting in 2016.
