The current method for implantation of the Ex-PRESS Glaucoma Filtration Device requires a conjunctival peritomy and shunt insertion under the guarded protection of a scleral flap. This technique requires suture closure of the flap and conjunctiva. A new minimally invasive technique for Ex-PRESS shunt implantation allows for insertion through a scleral tunnel originating from a grooved clear corneal incision. This new method avoids the need for conjunctival dissection and closure and offers the advantages of eliminating conjunctival wound leaks while maintaining the protection of a partial thickness scleral covering. This new technique may offer a faster safer means for shunt implantation with the potential for less conjunctival scarring.
