Introduction • Glaucoma drainage implants are specially indicated when the risks of failure with conventional trabeculectomy are high • NVG, uveitic glaucoma, etc. • When cataract and glaucoma coexist together in a patient with refractory glaucoma, critical management issues arise • Selection of the optimum glaucoma surgical procedure, sequence of surgery, etc • This procedure offers theoretical advantages like: • Avoid the high risk of failure associated with conventional filtering surgery • Improved IOP control in the long term and good visual rehabilitation • Less risk of blebitis – endophtalmitis • Single surgical procedure
Purpose • To examine theindications, safety, efficacyandcomplicationsofcombinedphacoemulsificationand Ahmed glaucoma drainageimplantsurgery.
Methods • Noncomparative, interventional, retrospective, consecutive case series of 24 eyes(21 patients). • 1 surgeon (LT) • Demographic characteristics Indications • Visual Acuity Complications • IOP and antiglaucoma medications : • Complete success IOP < 21mmHg w/o medications • Qualified success IOP < 21mmHg with medications • Failure IOP > 21mmHg +/- medications • Approved by FOLA EthicsComittee • StatisticalAnalysiswasperformedusing SPSS 16.0
* 7 eyes -> 1 previous surgery / 5 eyes -> 2 previous surgeries / 1 eye -> 3 previous surgeries **Hoffman et al. Combined Cataract Extraction and Baerveldt Glaucoma Drainage Implant .

Visual Acuity • Improved 79% (19), Maintened 21% (5) p < 0.0001 • Mean VA Preop 20/400 (HM to 20/30) Postop 20/80 (CF to 20/20)
IOP (mmHg) ↓ 41% p < 0.0001 * IOP at last visit
Antiglaucoma Medications N° of antiglaucoma medications ↓ 60 % p < 0.0001
Overall Outcome • 1. Complete success IOP < 21mmHg w/o medications • 2. Qualified success IOP < 21mmHg with medications • 3. Failure IOP > 21mmHg +/- medications

Conclusions • Combined phacoemulsification and Ahmed glaucoma drainage implant placement seems to be a safe and effective surgical option, providing good visual rehabilitation and control of IOP, with low incidence of complications.
