Corneal endothelial cell loss after trabeculectomy and phacoemulsification in one or two steps: a prospective study.
Soro-Martínez María Isabel, Miralles de Imperial-Ollero Juan Antonio, Pastor-Montoro Miriam, Arcos-Villegas Gabriel, Sobrado-Calvo Paloma, Ruiz-Gómez José María et al.
This study found combined phaco-trabeculectomy causes more corneal endothelial cell loss than either surgery alone, with one-step being safer than two-step.
