“…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.…”

Purpose To report on the long-term outcomes and risk factors for failure with the EX-PRESS shunt implanted under a scleral flap. Results Two hundred and forty-eight eyes of 211 consecutive patients were included. The mean IOP was reduced from 27.63 ± 8.26 mm Hg preoperatively (n ¼ 248) to 13.95 ± 2.70 mm Hg at 5 years (n ¼ 95). The mean follow-up was 3.46 ± 1.76 years. Complete and qualified success rates decreased gradually from 83% and 85% at 1 year to 57% and 63% at 5 years follow-up, respectively. The risk factors for failure were diabetes, non-Caucasian race, and previous glaucoma surgery. Complete success rates of diabetic patients and non-Caucasian patients decreased from 63% and 75% at 1 year to 42% and 40% at 5 years follow-up, respectively. Conclusions EX-PRESS success rates decrease over time but compare favourably with trabeculectomy literature data. The main identifiable risk factors for failure are diabetes, non-Caucasian race, and previous glaucoma surgery.

“…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.…”

“…7 The shunt has been shown to effectively lower IOPs postoperatively. [5][6][7][8] Those who advocate its use argue the shunts provide more predictable results with lower rates of hypotony. 7 We present an interesting case of a traumatic cataract resulting from damage to the lens from the Ex-PRESS shunt.…”

“…[2][3][4] It is now recommended that the device be implanted under a partial-thickness scleral flap to decrease the risk for these events. [5][6][7] We report another potential complication related to the device causing a traumatic cataract. To our knowledge, this has not been reported.…”
