3M.D. Associate Professor, Mersin University Faculty of Medicine, Department of Biostatistics, Mersin/TURKEY Purpose: To evaluate the effect of cataract surgery on visual prognosis as well as glaucoma follow-up and treatment in patients who have previously undergone trabeculectomy.
Materials and Methods: Seventeen eyes of 15 patients had undergone trabeculectomy with subconjunctival 0.2 mg/ml mitomycin C application in between 2003-2010. These eyes were treated with clear corneal phacoemulsification and posterior chamber intraocular lens implantation upon development of cataract and were enrolled in this retrospective study. The mean age of the patients (10 men, 5 women) was 67.53±13.19 years (range: 39-82 years).
Results: The eyes underwent cataract surgery 23.65±14.66 months (range: 4-56 months) after trabeculectomy. The visual acuity increased in almost all eyes after cataract surgery, but this was not statistically significant (p>0.05). Although the number of antiglaucomatous drugs used did not change significantly after cataract surgery, the mean intraocular pressure (IOP) decreased from 14.57±3.50 mmHg to 12.28±2.49 mmHg in the postoperative first month (p>0.05).
Conclusion: Cataract surgery in eyes with previous trabeculectomy may improve the visual performance and may augment IOP control.
