Abstract Details

Purpose:

The aim of this study is to evaluate the mid and long-term effectivness and safety profile of ab-interno trabeculotomy using the Kahook dual blade (KDB) device in patients with open angle glaucoma (OAG).

Setting:

Department of Ophthalmology, Hospital of Legnago, Verona.

Methods:

A total of 30 eyes from 22 glaucomatous patients with OAG were enrolled in a consecutive noncomparative case series. All the patients were treated with a 100° nasal trabeculotomy, using the KDB. Intraocular pressure (IOP), the number of medications, the complications were reported during the follow-up. The primary outcome were the postoperative IOP and the rate of complications.

Results:

KDB obtained a mean IOP reduction from 20.7±1.8 mmHg (baseline) to 16.4±2.1 mmHg after 6 months and 17.1±1.7 mmHg after a mean follow-up period of 14.2±3.1 months. The mean number of medications reduced between preoperative (n=2.3±0.6) and postoperative period (n=1.7±0.4). Cumulative probability of maintaining an IOP between 15 and 21 mmHg and/or 20% or greater reduction in IOP was 59.6% at 1 year. 8 patients presented with hyphema (<2mm) at the day 1 after surgery, reabsorbed spontaneously within 7 days.

Conclusions:

this technique achieved a moderate percentage of surgical success during the whole follow-up time and was a safe procedure with a very low rate of complications. KDB is an effective option for managing glaucoma in selected patients.
