The unmatched control group comprised eyes that underwent only cataract extraction. Data were collected preoperatively and postoperatively for 6 months. Data included spherical equivalent (SE), astigmatic error, intraocular pressure (IOP), and number of glaucoma medications.Results: The series included 76 consecutive OAG eyes with combined cataract plus trabecular microbypass stent and 50 consecutive non-OAG eyes with cataract surgery only. SE outcomes were equivalent between the groups (P<0.001). For the combined and cataract-only groups respectively, 46% vs 52% had SEs within 0.25 D of the target, 80% vs 80% within 0.50 D, and 95% vs 94% within 1.00 D. Astigmatism outcomes did not significantly differ between the groups (P>0.05). As for magnitude of astigmatism in the combined and cataract only groups respectively, 51% vs 32% were within 0.5 D, 75% vs 66% within 1.0 D, 87% vs 82% within 1.5 D, and 89% vs 94% within 2.0 D. In the OAG combined–surgery group, mean intraocular pressure reduction was 3.4 mmHg (P<0.0001) at 1 month postoperatively, 4.0 mmHg (P<0.0001) at 3 months, and 3.4 mmHg (P<0.01) at 6 months. Mean decrease in number of glaucoma medications was 0.4 (P<0.05) at 1 month, 0.7 (p<0.0001) at 3 months, and 0.9 (P<0.001) at 6 months.Conclusion: The results of this study suggest the trabecular microbypass stent is a refractively neutral device.Keywords: MIGS, glaucoma, refractive, outcomes, cataract surgeryScott RAFerguson TJStephens JDBerdahl JPDove Medical PressarticleMIGS Glaucoma Refractive Outcomes Cataract SurgeryOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 13, Pp 1331-1340 (2019)
