Kahook Dual Blade Goniotomy vs iStent : Long-Term Results in Patients with Open-Angle Glaucoma
Arnljots TS; Economou MAClinical Ophthalmology 2021; 15: 541-550
PURPOSE: Efficacy and safety evaluation of Kahook Dual Blade (KDB) goniotomy vs iStent implantation. MATERIALS AND METHODS: Retrospective study in patients that underwent goniotomy with KDB or iStent implantation, stand-alone or combined with cataract surgery. Main outcome parameters were intraocular pressure (IOP), number of glaucoma medications, proportion of eyes achieving >20% IOP reduction and number of eyes with postoperative IOP <19 mmHg at last follow-up. RESULTS: A total of 29 patients (30 eyes) were included in the iStent group and 30 patients (32 eyes) in the KDB group. Mean follow-ups were 20.9±6.5 (KDB-alone) to 29.5±7.6 (phaco-iStent ) months. Pre- and post-operative IOPs were 22.2±5.8 mmHg and 15.9±4.3 mmHg (=0.004) in the KDB-alone, 24.2±6.8 mmHg and 16.2±6.7 mmHg (=0.001) in the phaco-KDB, 20.6±5.4 mmHg and 20.9±6.8 mmHg (=0.598) in the iStent -alone as well as 20.9±5.5 mmHg and 15.6±3.4 mmHg (=0.003) in the phaco-iStent subgroups. No major complications occurred. CONCLUSION: All KDB and iStent subgroups except the stand-alone iStent subgroup showed a clinically significant IOP-lowering effect as a stand-alone procedure or combined with cataract surgery. Goniotomy with KDB in this setting seems to offer an advantageous IOP reduction compared to iStent .
