Ab-Interno Canaloplasty (ABiC) was the focus of three posters at the American Glaucoma Society (AGS) 2017 Annual Meeting in San Diego, California (March 2-5).
The following was true for all three studies:
- Analyzed ABiC alone and combined with cataract surgery
- Had 12-month data
- Showed a significant reduction in either average Intraocular Pressure (IOP), number of glaucoma medications required for IOP control, or both
- No serious complications were encountered
These studies further support what has already been known by experienced canaloplasty surgeons:
- It works
- It’s low risk
Additional studies will still be necessary to confirm that ABiC works as well and as long as Ab-Externo Canaloplasty. However, given its incredible safety profile combined with moderate IOP reduction, ABiC is poised to be an ideal surgical treatment option for anyone with uncontrolled moderate open angle glaucoma.
