Clinical Scorecard: Laser-Titratable Shunt Achieves IOP Reduction at 12 Months
At a Glance
| Category | Detail |
|---|---|
| Condition | Open-Angle Glaucoma |
| Key Mechanisms | Laser-adjustable aqueous shunt with nitinol valves for modulating outflow resistance. |
| Target Population | Patients with open-angle glaucoma. |
| Care Setting | Multicenter clinical study across India, Mexico, and Panama. |
Key Highlights
- 81% of implanted eyes set at the lowest resistance after 12 months.
- Mean IOP reduction of 35% from baseline.
- 93.5% of patients medication-free or using fewer medications.
- Bidirectional control of IOP with resistance adjustments.
- No intraprocedural adverse events reported.
Guideline-Based Recommendations
Diagnosis
- Assess IOP and medication use in patients with open-angle glaucoma.
Management
- Consider laser-adjustable shunt for postoperative IOP management.
Monitoring & Follow-up
- Regular follow-up for IOP measurements and medication adjustments.
Risks
- Potential for early hypotony; monitor for IOP rise with resistance adjustments.
Patient & Prescribing Data
42 patients with open-angle glaucoma in a multicenter study.
Most adjustments occurred early post-implantation, with significant IOP reduction.
Clinical Best Practices
- Utilize the Calibreye system for tailored postoperative IOP management.
- Monitor patients closely for medication needs and IOP changes.
- Educate patients on the potential for reversible adjustments.
