Thirty-one eyes (10.0%) required a subsequent glaucoma surgery during the follow-up.īoth laser platforms, the ExTra and the AIDA laser, used for Phaco-ELT lead to a significant reduction in intraocular pressure and anti-glaucoma drugs with no statistically significant difference in success rates during the follow-up of 12 months. Success rates were 80% (ExTra) and 70% (AIDA), respectively (p = 0.552). AGD reduction in the ExTra group was 1.3 ± 1.5 and 1.8 ± 1.4 in the AIDA group (p = 0.14). In the ExTra group, IOP was reduced to 12.8 ± 2.5 mmHg (−37%) and in the AIDA group to 14.7 ± 3.9 (−21%, p = 0.14) at 1 year. For The AIDA group (220 eyes), baseline IOP was 18.7 ± 6.3 mmHg on 2.0 ± 1.3 AGD and a BCVA of 0.3 ± 0.3. Baseline intraocular pressure (IOP) for the ExTra group (94 eyes) was 20.3 ± 5.9 mmHg on 2.0 ± 1.3 anti-glaucoma drugs (AGD) and a best-corrected visual acuity (BCVA, logMar) of 0.5 ± 0.4. Three hundred and fourteen eyes (mean age 75.9 ± 8.6 years) were included. Success was defined as IOP reduction of ≥ 20% compared to baseline plus an IOP of < 21 mmHg with no hypotony, no loss of light perception vision, and no subsequent glaucoma surgery. Data were collected preoperatively and postoperatively up to 1 year. In this retrospective chart review, inclusion criteria were a diagnosis of glaucoma and phaco-ELT between and. The aim of this study is to compare two laser systems for ELT (AIDA vs. Success was defined as >or=20% reduction in IOP without further glaucoma intervention.Īt 24 months, complete success rates were 53.3% for the ELT group and 40% for the SLT group (P=0.35, Fisher's exact test) qualified success rates were 33.3% for the ELT and 26.6% for the SLT group (P=0.5, Fisher's exact test).Mean IOP decreased from 25.0+/-1.9 to 17.6+/-2.2 mmHg (-29.6% P<0.0001) in the ELT group and from 23.9+/-0.9 to 19.1+/-1.8 mmHg (-21% P<0.0001) in the SLT group.īoth ELT and SLT proved to be effective techniques in the treatment of POAG refractory to medical therapy.Ĭataract surgery combined with excimer laser trabeculotomy (phaco-ELT) leads to a significant reduction in intraocular pressure by enhancing trabecular outflow. The main outcome measure was intraocular pressure (IOP) lowering after ELT and SLT. Approximately 50 adjacent, but not overlapping, laser spots were distributed over 180 degrees of the trabecular meshwork, using an energy level ranging from 0.7 to 1.0 mJ per pulse. The SLT patients were treated with a frequency-doubled q-switched neodymium:yytrium-aluminum-garnet laser (wavelength 532 nm). Eight spots were equally distributed at a distance of 500 microm from one another over the anterior trabeculum. ELT was carried out using a XeCl Excimer Laser with an emission wavelength of 308 nm. This prospective, randomized study included 30 consecutive eyes assigned randomly to either ELT or SLT group. To compare the effectiveness and safety of excimer laser trabeculotomy (ELT) ab interno vs selective laser trabeculoplasty (SLT) over 24 months of follow-up in patients with primary open-angle glaucoma (POAG) refractory to medical therapy.
