Phaco-iStent surgery effectively reduced intraocular pressure and glaucoma medications for 84 months. This glaucoma treatment showed sustained visual acuity improvements with minimal complications.

Area of Science:

  • Ophthalmology
  • Glaucoma Management
  • Surgical Interventions

Background:

  • Open-angle glaucoma requires long-term management to prevent vision loss.
  • Phacoemulsification with single-use iStent implantation is a minimally invasive glaucoma surgery option.

Purpose of the Study:

  • To evaluate the long-term efficacy and safety of combined phacoemulsification and single first-generation iStent implantation.
  • To assess the impact on intraocular pressure (IOP), medication use, and visual function over 84 months.

Main Methods:

  • A single-centre, prospective, uncontrolled interventional study.
  • Forty-one patients with open-angle glaucoma underwent phaco-iStent surgery.
  • Outcomes including IOP, glaucoma drops, visual acuity, and visual fields were monitored for 84 months.

Main Results:

  • At 84 months, mean IOP reduced by 4.87 mmHg and glaucoma drop usage by 0.59.
  • LogMAR visual acuity improved by 0.21, with stable visual fields.
  • High-risk patients showed a greater IOP reduction (6.85 mmHg) compared to low-risk patients (1.62 mmHg).
  • Complications were minimal, with one case of postoperative hyphaema.

Conclusions:

  • Phaco-iStent surgery offers sustained IOP and medication reduction over 7 years.
  • The procedure is associated with improved visual acuity and maintained visual function.
  • It represents a safe and effective treatment option for open-angle glaucoma, particularly for high-risk individuals.
