Resumo: Primary angle closure occurs as a result of crowded anterior segment anatomy, causing appositional contact between the peripheral iris and trabecular meshwork, thereby obstructing aqueous outflow. Several studies highlight the role of the crystalline lens in its pathogenesis. The objective of this work is to compare the long-term efficacy of phacoemulsification versus laser peripheral iridotomy (LPI) in the management of chronic primary angle closure (CPAC). Prospective case-control study with 30 eyes of 30 patients randomly divided in two groups: 15 eyes in the LPI group and 15 eyes in the IOL group. Patients in the LPI group underwent LPI using argon and Nd:YAG laser. Patients in the IOL group underwent phacoemulsification with posterior chamber intraocular lens (IOL) implantation. Examinations before and after the procedure included gonioscopy, Goldmann applanation tonometry, and anterior chamber evaluation using the Pentacam rotating Scheimpflug camera. The mean follow-up time was 31.13 ± 4.97 months. There was a statistically significant reduction in the intraocular pressure (IOP) and number of anti-glaucoma medications (p < 0.01) only in the IOL group. Anterior chamber depth, angle, and volume were all higher in the IOL group (p < 0.01) at the end of the follow-up period. Phacoemulsification with posterior chamber IOL implantation results in a higher anterior chamber depth, angle, and volume, when compared to LPI. Consequently, phacoemulsification has greater efficacy in lowering IOP and preventing its long-term increase in patients with CPAC and cataract.
