Microbypass stent implantation with cataract extraction and endocyclophotocoagulation versus microbypass stent with cataract extraction for glaucoma.
Ferguson Tanner J, Swan Russell, Sudhagoni Ramu, Berdahl John P
AI Summary
Adding endocyclophotocoagulation (ECP) to microbypass stent and cataract surgery for glaucoma significantly improved intraocular pressure reduction, especially for severe cases, offering a more effective combined treatment option.
Abstract
Purpose
To compare the outcomes of combined microbypass stent implantation, cataract extraction, and endocyclophotocoagulation (ECP) with those of implantation of the same microbypass stent with concomitant cataract surgery in patients with open-angle glaucoma (OAG).
Setting
Private Practice, Sioux Falls, South Dakota, USA.
Design
Retrospective consecutive case series.
Methods
Patients from January 2015 to August 2016 were included. The study group comprised eyes that had implantation of a microbypass stent in combination with cataract extraction and ECP. To compare outcomes, a control group of eyes with similar baseline characteristics that had implantation of a stent in combination with cataract surgery was established. Data were collected preoperatively and postoperatively at 1 day, 1 week, and 1, 3, 6, and 12 months. Data included intraocular pressure (IOP) and number of glaucoma medications.
Results
The mean preoperative IOP was 21.49 mm Hg ± 9.56 (SD) in the study group (51 eyes) and 20.66 ± 3.23 mm Hg in the control group (50 eyes). Twelve months postoperatively, the mean IOP reduction was 7.14 mm Hg in the study group and 4.48 mm Hg in the control group and the medication reduction was 38% (0.68) and 63% (1.06), respectively.
Conclusions
Patients who had implantation of the microbypass stent in combination with cataract surgery and ECP had significantly better IOP reduction than those who did not have ECP. The combination procedure was also effective in patients with severe OAG.

Patients who underwent implantation of a microbypass stent in combination with cataract surgery and endocyclophotocoagulation (ECP) had a significantly better intraocular pressure (IOP) reduction than those who did not have ECP.
The combination procedure of microbypass stent implantation with cataract extraction and endocyclophotocoagulation (ECP) was effective in patients with severe open-angle glaucoma (OAG).
Twelve months postoperatively, the mean intraocular pressure (IOP) reduction was 7.14 mm Hg in the study group (microbypass stent, cataract extraction, and endocyclophotocoagulation) and 4.48 mm Hg in the control group (microbypass stent with cataract surgery).
Twelve months postoperatively, the medication reduction was 38% (0.68 medications) for the study group (microbypass stent, cataract extraction, and endocyclophotocoagulation) and 63% (1.06 medications) for the control group (microbypass stent with cataract surgery).
In patients with open-angle glaucoma, the mean preoperative intraocular pressure (IOP) was 21.49 mm Hg 9.56 (SD) in the study group (51 eyes) and 20.66 3.23 mm Hg in the control group (50 eyes).
