KẾT QUẢ ĐIỀU TRỊ ĐỤC BAO SAU THỨ PHÁT SAU MỔ PHACO BẰNG LASER YAG TẠI BỆNH VIỆN NGUYỄN TRI PHƯƠNG

Abstract

Background: Posterior capsular opacification is the most common late complication after phaco surgery. Regarding the treatment of posterior capsule opacities, the Nd:YAG laser posterior capsule opening procedure is still the most modern and effective method. Therefore, we carried out this study to evaluate the treatment results of posterior capsular opacities secondary to phaco surgery with Nd:YAG laser. Objectives: (1) To investigate the posterior capsular opacities, (2) To evaluate the visual acuity improvement after laser procedure, (3) To record the laser energy level in treatment and procedure complications. Materials and methods: A prospective descriptive study on 68 patients with secondary posterior capsular opacities II-III after phaco surgery who underwent posterior capsule opening with YAG laser at Nguyen Tri Phuong Hospital from January to September 2020. Results: The study group had 39 female patients (57.4%) and 29 male patients (42.6%); the average age was 67.78 ± 9.6 age. The mean time from phaco surgery to laser was 3.15 ± 1.31 years. The posterior capsular opacification was more common in 54.4% fibrous form than in pearly 27.9% and 17.6% mixed forms. Average visual acuity before laser 0.26 ± 0.1; Average visual acuity after laser 0.67 ± 0.1, maintained until the 6th month. Average laser energy 64.5 ± 16.2 mJ. No dangerous complications. Conclusions: YAG laser is a safe and effective treatment method to restore vision in patients with posterior capsular cataract, the patient does not need to be hospitalized.
