Purpose

To analyze the therapeutic effects, prognostic factors, and complications that occurred after iStent® or iStent inject® implantation in South Korean glaucoma patients.

Setting

Incheon St. Mary's Hospital

Methods

We retrospectively analyzed 42 eyes of South Korean glaucoma patients, who were followed-up for more than 6 months after iStent® or iStent inject® implantation alone or combined with cataract surgery. Surgical success was defined as an intraocular pressure (IOP) ≤21 mmHg and an IOP reduction ≥20% from preoperative IOP levels.

Results

The cumulative success rate at 6 months after surgery was 45.3 ± 8.1% for iStent inject® alone (group A), 28.6 ± 13.1% for iStent® alone (group B), 81.2 ± 6.8% for iStent inject® combined with cataract surgery (group A-1), and 27.3 ± 21.8% for iStent® combined with cataract surgery (group B-1). Group A-1 showed a higher success rate than group B-1 (p = 0.007); the difference in success rates between groups A and B was not statistically significant (p = 0.579). When the success prognostic factors were analyzed by Cox regression analysis, the results showed that a higher preoperative IOP was associated with a higher surgical success rate (hazard ratio 0.80, p = 0.02).

Conclusions

In our patient group, iStent inject® was more effective than iStent® in combination with cataract surgery. The higher the preoperative IOP, the higher the surgical success rate; the results were significant.
