Analysis of effectiveness and influencing factors of phacoemulsification combined with IOL implantation in the treatment of PACG / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM: To analyze the effectiveness and influencing factors of phacoemulsification combined with intraocular lens(IOL)implantation in the treatment of primary angle-closure glaucoma(PACG). <p>METHODS: Clinical data of 75 patients(75 eyes)with PACG who received phacoemulsification and IOL implantation in our hospital from January 2017 to December 2018 were retrospectively analyzed. Postoperative intraocular pressure(IOP), best-corrected visual acuity(BCVA), changes of anterior segment and incidence of complications were counted. The patients were grouped by efficacy, and multivariate Logistic regression analysis was performed to analyze the risk factors influencing the effectiveness of phacoemulsification and IOL implantation in patients with PACG. <p>RESULTS: Postoperative IOP of patients with PACG was decreased while BCVA was increased, and there were statistically significant differences compared with those before operation(<i>P</i><0.05). Central anterior chamber depth(ACD), angle opening distance(AOD500), trabecular iris angle(TIA500)and angle recess area(ARA)were increased significantly compared with those before operation(<i>P</i><0.05). Multivariate Logistic regression analysis showed that chronic PACG and preoperative IOP were independent risk factors for efficacy of phacoemulsification and IOL implantation in patients with PACG(<i>P</i><0.05). <p>CONCLUSION: Phacoemulsification combined with IOL implantation has good efficacy and safety in the treatment of PACG. However, it is necessary to pay attention to preoperative IOP control. What's more, it should be carefully considered whether this operation is necessary for patients with chronic PACG.
