Abstract Details


The Cypass Microstent (Transcend Medical, USA) is a biocompatible polyamide implant inserted in the suprachoroidal space combined with alone or combined with cataract surgery to improve aqueous humor outflow through the uveoscleral pathway.


Clinic of Ophthalmology, St. Johannes Hospital, Dortmund, Germany


In a retrospective clinical study, 220 mild to moderate glaucoma findings were treated with a cypass implant alone (Group 1: 98 patients) or combined with cataract surgery (Group 2: 122 patients). The follow-up time of the study was 1 year.


The mean preoperative intraocular pressure (IOP) was 19.11 (± 8.22) mmHg in group 1 und 20.85 (± 8.34) in group 2. The mean IOP was 15.17 (± 5.85) mmHg 12 months postoperatively (percent pressure reduction: 20.62%, p <0.05) in group 1 and 18.61 (± 6.86) mmHg (percent pressure reduction: 10.74%, p > 0.05). The reduction of the number of glaucoma eye drops is 39,8 % in the group 1 and 23,3% in the group 2. In small number of patients (20,45%), additional surgical procedures were performed by cases that failed to reach the target pressure.


Patients with combined cypass and cataract surgery had a significant reduction not only of the intraocular pressure but also the number of the glaucoma eye drops after one year. Both groups of patients had a similar safety profile with minor complications.
