Long-term results of combined 1-way phacoemulsification, intraocular lens implantation, and trabeculectomy.

PURPOSE: To analyze the results of 1-way phacoemulsification and posterior chamber intraocular lens (IOL) implantation combined with trabeculectomy.

SETTING

Department of Ophthalmology and Neurosurgery, University of Siena, Siena, Italy.

METHODS

This retrospective study comprised 42 eyes of 36 patients with glaucoma and cataract who had phacoemulsification with posterior chamber IOL implantation combined with trabeculectomy. The mean follow-up of 28.24 months +/- 10.99 (SD) (range 11 to 52 months) included measurement of intraocular pressure (IOP), visual acuity, visual field, endothelial cell loss, and notation of complications.

RESULTS

There was a statistically significant postoperative improvement in visual acuity (P < .001). Mean preoperative best corrected visual acuity (BCVA) was 20/200 (range 20/30 to hand movements). Mean 1 year postoperative BCVA was 20/30 (range 20/20 to 20/60). The preoperative mean IOP of 24.06 mm Hg decreased to 15.36 mm Hg at 1 year (P < .001). All 42 eyes had a postoperative IOP of less than 21.00 mm Hg. Mean central cornea endothelial cell density preoperatively was 2238 +/- 396 cells/mm2 (range 1697 to 2906 cells/mm2) and postoperatively, 2005 +/- 397 cells/mm2 (range 1302 to 2801 cells/mm2). Early postoperative complications consisted of a choroidal detachment in 2 patients (4.76%). Three and 4 days after surgery, respectively, 2 patients (4.76%) had surgery to remove viscoelastic substance under the IOL. Late complications included posterior synechias in 3 eyes (7.14%). One year after surgery, because of a significant decrease in vision, a neodymium:YAG laser posterior capsulotomy was necessary in 2 eyes, 1 with an acrylic IOL (3.70%) and 1 with a silicone lens (9.09%).

CONCLUSION

Combined phacoemulsification, posterior chamber IOL implantation, and trabeculectomy was safe and effective in patients with coexisting glaucoma and cataract.
