Intraocular pressure (IOP) outcomes of phacotrabeculectomy and phacocanaloplasty during follow-up. A highly significant reduction of IOP was found for both groups during follow-up (P < .0001). Except for the first postoperative day, statistical analyses revealed no significant difference for postoperative IOP results between both groups. Box plots illustrate the median (50th percentile) as a black center line and the 25th and 75th percentile as the lower and upper hinges of the box. Circles represent minor outliers and stars major outliers.
