Abstract Details

Purpose:

To evaluate the safety and effectiveness of a novice stainless-steel supraciliary implant (SSSI) for reducing intraocular pressure (IOP) in patients with open-angle glaucoma (OAG).

Setting:

Ophthalmic unit of Skhodnya city hospital, Moscow province; Department of ophthalmology Medical institute People's friendship university of Russia, Moscow, Russian Federation.

Methods:

Seventeen patients who exhibited OAG (age 74.5+6.7 years) underwent ab interno implantation of SSSI. A custom-designed spatula inserted through a clear corneal incision was used to detach the ciliary body from the sclera, creating a cleft 2.0-2.5 mm wide and 6.0-6.5 mm deep. A SSSI was implanted in the supraciliary space using forceps. The primary outcome measure was IOP change; secondary outcomes were use of hypotensive medication(s), complications, and requirement for a second surgery. Reduction in IOP >20% and IOP 6-21 mmHg without medication constituted complete success; with medication – partial success. The follow-up period was 1 year.

Results:

Baseline IOP and hypotensive medication use were 22.2 ± 6.2 mmHg (95% confidence interval (CI), 19.2-25.1) and 2.8 ± 1.0 (95% CI, 2.3-3.2). At 6 and 12 months, complete success was respectively achieved in 31.2% and 28.6% of patients; partial success was respectively achieved in 50% of patients. Failure occurred in 3 patients; in 2 patients after 1 week and in 1 patient after 6 months.  Failure was because of cleft closure by fibrosis. Intraoperative haemorrhage at the cleft site was observed in 70.6% of patients. Postoperative hyphema was present in 3 patients (17.6%) but resolved spontaneously.

Conclusions:

SSSI is safe and effective for reducing IOP in OAG patients.
