Sustained IOP reduction is more important than ever to meet the long-term vision preservation needs of today’s glaucoma patients.1

    Earlier Surgery

    “Achieving lower pressures early on with safer options for patients will be beneficial in the long run.”

  • Video player still image of Dr I. Paul Singh

    Predictable Post-op

    “A device that enables IOP control even after a patient leaves our practice could help us better prevent progression.”

What is your experience?

Answer a question and see how your response compares with your peers’

How would a novel surgical device that achieved—and sustained—IOP similar to filtration therapy but with fewer adverse events change your approach to earlier surgery?

A lack of sustained low IOP in more-advanced POAG patients is a barrier to vision preservation1

While it can achieve low IOP, trabeculectomy’s complication rates prevent it from being an earlier surgical option2,3

*Based on findings from the Tube Versus Trabeculectomy (TVT) Study. Early complications: choroidal effusion, shallow/flat anterior chamber, wound leak, hyphema, aqueous misdirection, suprachoroidal hemorrhage, vitreous hemorrhage, decompression hemorrhage, decompression retinopathy, cystoid macular edema. Late complications: persistent corneal edema, dysesthesia, encapsulated bleb, choroidal effusion, cystoid macular edema, hypotony maculopathy, persistent diplopia, bleb leak, endophthalmitis/blebitis, chronic or recurrent iritis, retinal detachment, corneal ulcer, shallow/flat anterior chamber.2

Trabeculectomy success rates fall to only about 50% by 5 years post-op3,4

Trabeculectomy may achieve low IOP and reduce medication burden, but failure rates increase over time.

Device innovation is needed to produce more-sustainable results to enable long-term vision preservation.1,4
