Phacoemulsification in patients with primary angular closure

Abstract

Introduction: there is currently a tendency toward phacoemulsification in the primary angular closure due to the crucial role of the lens in the pathophysiology of the disease. Objective: to describe the results of phacoemulsification in patients with primary angular closure in Pinar del Río. Method: a prospective longitudinal descriptive study was carried out in Pinar del Río, between January 2013 and December 2015, which included 43 patients with primary angular closure not controlled by laser peripheral iridotomy or medical treatment, who underwent phacoemulsification. Statistical analysis was performed using the SPSS program. Results: mean age was 54.67 ± 4.22 years and 83.7% were women. The mean amplitude value of the anterior chamber was 2.56  0.11 mm increasing to 3.24  0.08 mm (p = 0.006). 93.02% of the eyes showed a narrow angle, and after treatment 83.72% presented a grade 3-4 (p <0.001). The best corrected average visual acuity varied from 0.74 to 0.98 (p = 0.042) and the refractive sphere from 3.25 to -0.43 diopters (p = 0.001). The intraocular pressure was modified from 26.7 ± 3.3 mmHg in the preoperative period to 15.1 ± 1.8 mmHg 6 months after surgery (p <0.001). The transoperative and postoperative complications were present in 2.3% and 4.7%, respectively. Conclusion: the results of phacoemulsification in patients with primary angular closure were satisfactory since an improvement in anatomic and refractory parameters was observed, with intraocular pressure control and a minimum of complications.
