“…Also, intraoperative use of viscoelastics may lead to impaired drainage through the GDD and transient IOP elevation. 17 Inflammatory mediators and cells released during cataract extraction could stimulate thickening of the fibrous capsule around the end plate with a resultant increase in IOP. Transient and permanent IOP elevation could adversely affect visual field and visual function.…”

“…One possible reason could be the flow of lens debris through the GDD tube into the bleb cavity during cataract surgery. Also, intraoperative use of viscoelastics may lead to impaired drainage through the GDD and transient IOP elevation 17. Inflammatory mediators and cells released during cataract extraction could stimulate thickening of the fibrous capsule around the end plate with a resultant increase in IOP.…”

Purpose: The aim was to investigate intraocular pressure (IOP) control after phacoemulsification in adult glaucomatous eyes with a functioning nonvalved Aurolab Aqueous Drainage Implant (AADI) compared with eyes that did not have cataract extraction post-AADI. Methods: In this retrospective study, we reviewed records of 47 patients (47 eyes) who had a clear corneal phacoemulsification after AADI placement with a minimum of 2 years of follow up. The control group included 89 patients (89 eyes) who had a functional AADI at 1 year, minimum of 3 years of follow up post-AADI implantation, and no cataract extraction. The main outcome measure was failure (IOP >21 mm Hg or increased by >20% from prephacoemulsification level requiring at least 1 additional glaucoma medication, IOP ≤5 mm Hg, reoperation for glaucoma, or loss of light perception vision). Results: The median interval between AADI and phacoemulsification was 11.5 months (range: 4 to 68 mo), and the mean follow-up time after phacoemulsification was 35.6±6.4 months. The cumulative probability of failure was 14% (95% confidence interval=6%-31%) in the phaco group and 6% (95% confidence interval=3%-13%) in the control group at 2 years (P=0.11). Mean IOP was reduced from 16.5±4.5 mm Hg preoperatively to 15.4±4.7 mm Hg at 2 years after phacoemulsification (P=0.10). Mean LogMAR visual acuity improved from 1.1±0.6 preoperatively to 0.6±0.7 at 2 years after phacoemulsification (P<0.001). Conclusions: In eyes with a pre-existing AADI, phacoemulsification resulted in visual improvement without a significant rise in IOP or increased risk of AADI failure after 2 years follow up.
