PURPOSE: Combined phacoemulsification plus excimer laser trabeculostomy (phaco-ELT) is a minimally invasive surgery that effectively reduces intraocular pressure (IOP) in patients with glaucoma and a concomitant diagnosis of cataract. The aim of this study was to evaluate the long-term treatment success as well as safety of phaco-ELT over an 8-year follow-up period. METHODS: Patients with a diagnosis of primary or secondary glaucoma or ocular hypertension and a visually significant cataract who underwent a combined phaco-ELT between January 1, 2008, and December 31, 2010, were included. Data for IOP, the number of IOP-lowering medications (meds), best-corrected visual acuity, complications, and subsequent surgeries to lower IOP were collected preoperatively (baseline) and intraoperatively as well as at 1 day, 1 week, 1 month, 3 months, 6 months, 9 months, 1 year, and every 6 months thereafter to 8 years postoperatively. RESULTS: One hundred sixty-one eyes of 128 patients were included. After 8 years of follow-up, the long-term treatment success rate with IOP ≤ 21 mmHg was 50.2%. No serious intra- or postoperative complications occurred. The mean IOP decreased significantly from 19.3 (±4.8) mmHg at baseline to 15.4 (±3.2, p =0.0040) mmHg at 8 years. Additionally, meds remained below baseline after 8 years of follow-up and were reduced significantly for up to 4 years. Only 25.5% of the eyes required a subsequent surgery to lower IOP during the follow-up period. CONCLUSION: Combined phaco-ELT is a safe procedure without serious intra- or postoperative complications, which has a positive long-term effect regarding IOP and meds. Remarkably, the mean IOP-lowering effect remained stable and was reduced ≥ 20% from baseline after 3 months for the remainder of the follow-up duration, whereas the number of meds was reduced significantly for up to 4 years. Furthermore, only 25.5% of the eyes required a subsequent surgery to control IOP throughout the whole follow-up of 8 years.
