Comparison of Safety and Efficacy of Hydrus and iStent combined with Phacoemulsyfication in Open Angle Glaucoma Patients a Long-Term Follow-Up
Purpose of the study is to compare the effectiveness and safety of two micro-invasive glaucoma surgery devices: Hydrus Microstent and iStent Trabecular Bypass in combination with cataract phacoemulsification in the treatment of open-angle glaucoma. We additionally analyze the impact of preoperative factors on achieving surgical success in both surgical methods.
Inclusion Criteria:
the cataract which had a significant effect on the visual acuity of the patients and one of the following conditions: progression of glaucoma in visual field confirmed by two consecutive examinations by the Humphrey visual field analyzer with SITA Standard 24-2 algorithm in the course of primary open-angle glaucoma despite the use of IOP-lowering medications (1 to 4 active ingredients) or patients not tolerating or adhering to the treatment.
Exclusion Criteria:
lack of consent for study participation, narrow-angle or closed-angle glaucoma, secondary glaucoma (including the course of psudoexfoliation syndrome, pigmentary glaucoma), advanced glaucoma, severe proliferative diabetic retinopathy, cloudy cornea, advanced macular degeneration, history of glaucoma surgical interventions (as well as trabeculoplasty), and use of more than four IOP-lowering medications
