Abstract Details

Purpose:

To describe intraocular pressure (IOP) and IOP-lowering medication outcomes of combined phacoemulsification and ab interno trabeculectomy with the Kahook Dual Blade (KDB; New World Medical, Inc, Rancho Cucamonga, CA) in adults with cataract and open-angle glaucoma (OAG).

Setting:

An academic practice in the UK.

Methods:

Retrospective chart review of existing medical records. Data collected included intraocular pressure (IOP) and IOP-lowering medication use preoperatively and through up to 24 months postoperatively. Paired t-tests were utilized to compare preoperative to postoperative mean IOP and mean medications used.

Results:

Data from 32 eyes of 26 subjects were analyzed. Subjects were predominantly Caucasian (25/26) had mean (standard error) age of 79.3 (1.2) years, and eyes had moderate-advanced OAG (mean visual field mean deviation -8.3 [1.2]). Mean IOP was 19.8 (0.8) mmHg at baseline and 15.4 (0.5) mmHg (p<0.0001) after mean follow-up of 12.0 (1.0) months; IOP reductions of >=20% were achieved in 21/32 eyes (65.6%). Mean IOP medication use declined from 2.4 (0.2) medications per eye at baseline to 0.5 (0.2) at last follow-up (p<0.0001); 24/32 eyes (75.0%) were medication-free at last follow-up. No vision-threatening complications were observed.

Conclusions:

Combined phacoemulsification and ab interno trabeculectomy with the KDB safely provided mean IOP reductions of 22% and mean IOP medication reductions of 80% after mean follow-up of 12 months in eyes with moderate to advanced OAG. This procedure provides medication-independence in most eyes with statistically and clinically significant IOP reductions.
