Comparison of Ex-PRESSTM Mini Glaucoma Shunt to Trabeculectomy in Subjects With Open Angle Glaucoma

"Standard trabeculectomy procedure~1. Creation of a fornix or limbal based conjunctival flap in upper quadrants~2. Creation of a limbal-based scleral flap extending into clear cornea~3. Delicate application of MMC solution onto sclerectomy bed. (MMC concentration 0.4mg/ml for 1-3 minutes)~4. Creation of fistula 1mm x 2mm in size~5. Iridectomy~6. Suturing the scleral flap~7. Repositioning of conjunctiva with sutures After procedure, antibiotics \& steroids are administered topically; eye is covered with a pad - patient is discharged."

"Ex-PRESS implantation procedure:~1. Creation of a fornix or limbal based conjunctival flap in upper quadrants~2. Creation of limbal-based scleral flap extending into clear cornea~3. Delicate application of MMC solution onto sclerectomy bed. (MMC concentration 0.4mg/ml for 1-3 minutes)~4. Penetration into anterior chamber using 23-25G needle, halfway between the white sclera and clear cornea (in the center of the grey zone);creation of track incision at limbus~5. Prior to implantation, a thorough mobility check should be performed~6. Implantation of Ex-PRESS implant loaded on its introducer, through that pre-incision~7. Withdrawal of introducer~8. Tucking plate under the scleral flap, and verification of its position~9. Suturing scleral flap After implantation procedure, antibiotics \& steroids administered topically; eye is covered with a pad - patient is discharged."
