Abstract
Objective: To evaluate the outcomes of cataract surgery following glaucoma filtering surgeries carried out at the University College Hospital, Ibadan. Methods: This study was a retrospective review of the records of patients who had cataract surgery following glaucoma filtering surgery. Outcomes of interest include change in visual acuity with cataract surgery following glaucoma filtering surgery, time from glaucoma filtering surgery to cataract surgery, change in intraocular pressure control with cataract surgery and glaucoma filtering surgery complications. Paired t-test and Chi-squared tests were carried out for differences in means and categorical data respectively. Results: Thirty-one eyes of 27 patients were evaluated. Mean (SD) age was 56.7 years (15.4). Sixteen (59.3%) patients were males. The median time from glaucoma surgery to cataract surgery was 21 months (6-180 months). The number of eyes with visual acuity > 6/18 increased from four (13%) pre-operatively to 19 (61.3%) post-cataract surgery. There was no statistically significant difference (P = 0.295) between mean intraocular pressure before surgery (15 mmHg, SD = 5.5) and at last follow-up visit (16.6 mmHg, SD = 7.4). Conclusion: Outcomes of cataract surgery following glaucoma filtering surgery can be optimized with careful patient selection and meticulous perioperative care.
