Outcomes of Combined Manual Small Incision Cataract Surgery and Trabeculectomy
Background: Within the aging population, coexisting of glaucoma and cataract is frequent. The treatment of either condition can influence the course of the other. Cataract extraction, glaucoma filtration surgery or combined procedures are the management options. The choice of procedure depends on the level of visual impairment, severity of glaucoma, level of intraocular pressure and other factors.
Objective: The study was aimed at assessing the outcome of combined manual small incision cataract surgery and trabeculectomy in lowering intraocular pressure and restoration of vision.
Methods and Patients: A retrospective chart review of one year follow-up of patients who under went combined manual small incision cataract surgery and trabeculectomy at Menelik II Hospital.
Results: Forty-nine eyes of 43 patients were included in the study. Pre-operative intraocular pressure decreased from mean 27.04 mmHg to 13.41 mmHg at 12 months postoperative follow-up, with mean reduction of 13.63 mmHg. Hypotensive medication was not required in 71.4% of the operated eyes. Visual acuity, which was less than 6/18 in all eyes on Snellen chart improved to greater than 6/18 in 35 eyes, 71.4%.
Conclusion: Combined manual small incision cataract surgery and trabeculectomy is effective in terms of IOP control and vision restoration in treating patients with coexisting cataract and glaucoma.
Recommendation: The procedure is doable and cost effective for eye care professionals who handle glaucoma patients and practicing manual small incision cataract surgery.
