Abstract Details

Purpose:

To evaluate a novel MIGS technique that combines Dual Blade Goniotomy and Direct Viscodilation of the collector channels with cataract surgery for the reduction of IOP and decreased dependence on glaucoma medications.

Setting:

This report is a retrospective study of glaucoma patients who presented for cataract surgery in a private clinic. All surgery was performed by one surgeon (L.L.B.).

Methods:

Following standard cataract surgery, 180º of trabecular meshwork was removed with the Kahook Dual Blade. The exposed ostia of the collector channels were directly viscodilated. IOP was checked for initial steroid response and at 3 month intervals thereafter.

Results:

Moderate to severe glaucoma comprised half of the 80 eyes at one year follow-up. 40% had previous glaucoma surgery. 60% were diabetics. 50% were on anticoagulants. 80% were African Americans. The initial mean IOP was 19.9mmHg (SD+/- 5.5) with a mean of 1.9 medications. At three months, mean IOP decreased to 15.4mmHg and remained steady around 16.3mmHg through the first year. A blush of blood in Schlemm’s canal was common, but dissipated by two weeks. IOP was reduced by 18%. 91% of eyes required no medications and there was a 92% reduction in the total number of medications.

Conclusions:

The synergy of the Goniotomy-Viscodilation-Cataract technique is responsible for the marked elimination of medications in this study. This has major impact on the reduction of compliance issues and the financial burden of glaucoma therapy.
