Retrospective analysis of indications and outcomes of trabecular micro-bypass stent implantation in Indian eyes
Amit Pandey, Harsh Kumar, Abhishek Kathuria, Sagarika Patyal, Swati Singh, Bhavini PandeyPurpose:
To analyze the patient characteristics, initial outcomes, and complications associated with iStent implantation in Indian eyes.
Methods:
This retrospective case series comprised subjects who underwent iStent, iStent inject, or iStent inject W implantation as a standalone procedure or combined with phacoemulsification with at least 12 months follow-up. The main outcome measures were change in intraocular pressure (IOP) and number of anti-glaucoma medication (AGM), post op complications, and resurgery rates at the final follow-up.
Results:
A total of 56 eyes of 46 patients were included. Twenty-six eyes received iStent, and 30 eyes received either iStent inject or iStent inject W. Mean IOP reduced by 25.5%, and the mean number of AGM decreased by 75.8% at final follow-up (
Conclusion:
iStent implantation in Indian eyes demonstrated promising outcomes in reducing both intraocular pressure and anti-glaucoma medication burden. While combined procedures exhibited superior efficacy in reducing IOP and AGM, postoperative complications such as steroid-induced IOP rise were observed, emphasizing the importance of careful monitoring and management in optimizing surgical outcomes.
