Ex-PRESS Miniature Glaucoma Device Implanted Under a Scleral Flap Alone or Combined With Phacoemulsification Cataract Surgery

Abstract

The use of the Ex-PRESS implant under a scleral flap was effective for lowering IOP both alone and combined with cataract surgery. The most common device-related complication was tube blockage, which was treated with the Nd:YAG laser.

Long-term outcomes and risk factors for failure with the EX-press glaucoma drainage device

“…Our longterm outcomes are similar to the previous short-and mid-term results reported earlier. 1,3,4,[8][9][10][11][12][13][16][17][18][19][20][23][24][25] The complete success rate in our study shows a decline from 83% at 1 year to 57% at 5 years. In a similar manner, de Jong et al 20 report on a complete success rate decline from 86.8% at 1 year to 59% at 5 years with the EX-PRESS.…”

Comparison of trabeculectomy and Ex-PRESS implantation in fellow eyes of the same patient: a prospective, randomised study

“…The original sub-conjunctival placement has now been completely abandoned for a safer implantation under a scleral flap. [13][14][15][16][17][18][19][20] The latter procedure closely resembles trabeculectomy, but offers the advantages of a standard (stented) sub-scleral outflow route that obviates sclerostomy and peripheral iridectomy.…”

Novel Glaucoma Surgical Devices

“…(Kanner et al, 2009) They found that the Ex-PRESS implant under a scleral flap could lower IOP alone or in combination with cataract surgery. The most common device-related complication was blockage of the lumen of the implant, which was effectively treated with Nd:YAG laser treatment of the tube tip in the anterior chamber.…”
