| Abstract | dc.description.abstract | Purpose: To examine the indications, safety, efficacy, and complications of combined
phacoemulsification and Ahmed glaucoma drainage implant surgery.
Methods: A retrospective case review of 35 eyes (31 patients) subjected to combined
phacoemulsification and Ahmed glaucoma drainage implant surgery. Demographic characteristics
of the study population, indications for combined surgery, and operative and postoperative
complications were recorded. Visual acuity, intraocular pressure (IOP), and number of glaucoma
medications were evaluated preoperatively and postoperatively. Complete success was defined as
IOP <= 21mm Hg without medication, qualified success if IOP <= 21 mm Hg with >= 1 medications,
and failure if IOP > 21 mm Hg or <= 5 mm Hg on >= 2 consecutive visits.
Results: Mean follow-up was 29.5 months (range, 6 to 87 mo). The most common indication for
combined surgery was a history of prior failed trabeculectomy (60%). Postoperative visual acuity
improved in 30 of 35 eyes (85%) (P < 0.01) regardless of the indication for combined surgery. IOP
was reduced from a mean of 24.7 to 15.0 mm Hg at the last follow-up visit (P < 0.01). The number
of IOP-lowering medications was reduced from a median of 3.1 preoperatively to 1.7 at the last
follow-up (P < 0.01). Overall, there were 31 eyes (89%) classified as qualified success and 4 eyes
(11%) as complete success. The most common postoperative complication was a hypertensive
phase in 18 eyes (51%).
Conclusions: Combined phacoemulsification and Ahmed glaucoma drainage implant surgery seems
to be a safe and effective surgical option, providing good visual rehabilitation and control of IOP for
patients with refractory glaucoma and cataract. | es_ES |
