Purpose
To evaluate the efficacy and safety of the iStent inject in patients with POAG combined with cataract surgery.
Setting
Ophthalmology department, Colchester hospital, UK
Methods
A retrospective, uncontrolled, interventional case series. Fifty six eyes with primary open-angle glaucoma were reported. All subjects underwent ab interno implantation of 2 iStent inject implants together with cataract surgery.
Surgical procedures done by three experienced glaucoma consultants.
Patients were assessed at postoperative week 1, months 1 and 3, and quarterly, thereafter. Data collected included visual acuity, intraocular pressure (using Goldmann tonometry), number of postoperative glaucoma medications, and possible complications.
Results
Fifty six eyes of POAG treated with iStent combined with cataract surgery during the period from January 2020 to November 2020. The minimum follow up period was 3 months and the maximum period was 10 months ( average 8.8± 3 month). The mean visual acuity was 0.51± 1 logMAR at baseline that improved to 0.21±2 at the end of postoperative follow up period of each patient. Twenty five patients (44.6 %) achieved reduction of their intraocular pressure with average reduction of 4.1±1 mmHg (p=0,00001). Twenty patients (35.7) remained unchanged , while 11 patients (19.6) got IOP elevation in comparison with their preoperative baseline IOP. The mean number of preoperative glaucoma drops was 2.1±3 which decreased by 0.94±3 ( p=0.000004). Three patients developed early post operative hyphema ( 2 microscopic hyphema and 1 macroscopic hyphema); all were controlled well medically.
Conclusion
The iStent inject proved to be a safe and effective treatment for patients with POAG combined with cataract surgery. Insertion resulted in a significant decrease in intraocular pressure as well as the number of topical antiglaucoma medications. Few cases reported of manageable postoperative complications.
