Early Post – Operative Intraocular Pressure Rise between Phacoemulsification and Phacotrabeculectomy in Primary Open Angle Glaucoma Patients: A Comparison
Journal Title: International Journal of Contemporary Medical Research - Year 2017, Vol 4, Issue 3
Abstract
Introduction: Phacoemulsification with intraocular lens implantation and triple procedure (phacoemulsification with intraocular lens implantation with trabeculectomy) are associated with a significant intraocular pressure rise during the early post – operative period. The study was undertaken to compare the outcome with respect to early post – operative intraocular pressure rise between phacoemulsification and phacotrabeculectomy in primary open angle glaucoma patients with moderate optic nerve head damage and visually significant cataract. Material and Methods: Out of 95 patients, 41 underwent phacoemulsification and 54 underwent phacotrabeculectomy. Intraocular pressure was measured 6 hours after surgery. Results: The patients’ age, sex ratio and ratio of right eye to left eye did not differ significantly between the two groups. In phacoemulsification group, pre - operative intraocular pressure was 16.32 ± 2.09 mm Hg and intraocular pressure at 6 hours was 16.41 ± 3.52 mm Hg. Change in intraocular pressure was statistically not significant (P = 0.863). In phacotrabeculectomy group, pre - operative intraocular pressure was 17.39 ± 2.57 mm Hg and intraocular pressure at 6 hours was 16.07 ± 4.11 mm Hg. Change in intraocular pressure was statistically not significant (P = 0.053). A total of 6 patients in phacoemulsification group and 2 patients in phacotrabeculectomy group had an intraocular pressure rise of ≥ + 5 mm Hg. Change in intraocular pressure at 6 hours between the two operative groups was statistically not significant (P = 0.268). Conclusion: We found no added advantage in doing a phacotrabeculectomy as against phacoemulsification with respect to early post - operative intraocular pressure spikes in primary open angle glaucoma patients with moderate glaucomatous damage and visually significant cataract.
