The pressure ridge is designed to confine aqueous to the primary drainage space. This space has a volume approximately equal to 10-15% of aqueous from the anterior chamber. The primary drainage area is intended to function like a drain with a small surface area. This enables the short-term benefit of reduced complications from excessive filtration.

A fully functioning bleb will be visible over the entire plate surface. The plate incorporates two peripheral fenestrations. These fenestrations are intended to secure the implant in place with fibrous tissue and limit the potential for the bleb to effect rectus muscle function.
