PURPOSE: To evaluate the safety and efficacy of the iStent inject device combined with phacoemulsification in Asian eyes with primary open angle glaucoma. METHODS: A retrospective study of combined phacoemulsification and iStent inject surgeries performed in a single institution from July 2017 to August 2019 on patients with co-existing cataracts and primary open angle glaucoma (POAG). Outcome measures included best-corrected visual acuity, intraocular pressure (IOP), number of glaucoma eyedrop medications, and surgical complications. RESULTS: A total of 95 eyes were included. Majority of subjects were male (59, 62.1%) and Chinese (83, 87.4%). Mean age was 74.7 ± 8.7 years. Pre-operatively, mean IOP was 16.2 ± 4.3 mmHg and number of medications was 1.9 ± 0.9. Significant post-operative reduction in mean IOP was observed at all timepoints - post-operative month (POM)1: 3.0 ± 5.6 mmHg reduction ( = 95, < 0.05); POM3: 1.6 ± 3.8 mmHg ( = 66, < 0.05); POM6: 1.8 ± 4.7 mmHg ( = 55, < 0.05); POM12: 1.3 ± 4.2 mmHg ( = 48) ( < 0.05). The number of glaucoma medications was also reduced from a mean of 1.9 ± 0.8 to 0.6 ± 1.0 at POM12 ( < 0.05). Intraoperatively, one case of malignant glaucoma occurred. Post operatively, implant obstruction by iris was observed in two eyes post-operatively requiring iridoplasty. One case of cystoid macular edema and one case of drop in visual acuity due to glaucoma progression was/were also observed. CONCLUSION: Asian eyes undergoing combined phacoemulsification and iStent inject surgery demonstrate a significant and sustained reduction in both IOP and number of glaucoma medications. Overall, there is a good safety profile for iStent inject.
