Purpose:
To describe a novel surgical technique to manage over-implantation of the iStent inject intra-operatively, utilizing only the iStent inject delivery system itself to perform both device extraction and reimplantation, without the need for additional instrumentation.
Methods:
A demonstration of managing over-implantation of the iStent inject, with two case examples.
Results:
Over-implantation of the iStent inject can be successfully managed intra-operatively to ensure ideal positioning to optimise post-operative outcomes, with the use of only the iStent inject delivery system itself for both device extraction and reimplantation.
Conclusion:
This novel technique provides a cost-effective and feasible means to intra-operatively manage over-implantation of the iStent inject.
