Combined intraocular lens implantation and glaucoma implant (tube shunt) surgery in pediatric patients: a case series.
Objective: We sought to investigate the outcomes of children who underwent simultaneous intraocular lens (IOL) implant and glaucoma implant surgery.
Methods: Medical records of all patients who underwent simultaneous IOL implant and glaucoma implant surgery from January 1995 through August 2003 by a single surgeon were reviewed. Criteria for success included intraocular pressure
Results: The study included 9 eyes of 8 children who had a mean age of 7.6 years (range, 1-16) and a mean follow-up time of 21 months (range, 8.5-35 months) after simultaneous IOL (either cataract removal with primary IOL, 2 eyes; or secondary IOL implantation, 7 eyes), and glaucoma implant surgery (6 Baerveldt, 3 Ahmed). The indications for combined surgery fell into 3 basic categories: unilateral aphakia with glaucoma (4/9), anatomical features (such as shallow anterior chamber and/or vitreous in the pupillary plane) making an IOL helpful in positioning the tube away from corneal endothelium and/or vitreous (4/9), and unilateral traumatic cataract (1/9). Mean intraocular pressure for operated eyes was 29 mm Hg (range, 21-44) preoperatively and fell to 17 mm Hg (range, 11-22) at last follow up, P = 0.01. The mean number of glaucoma medications was 3.5 preoperatively (range, 2-5) versus 1.9 (range, 0-4) at last follow-up (p = NS). Complications (n = 5) were varied, only 2 of which required additional surgery. Eighty-nine percent (8/9) of patients met criteria for success at last follow-up.
Conclusions: Selected children can do well after combined glaucoma implant and IOL surgery, achieving both satisfactory glaucoma control and stable visual acuity.
