Personalized approach for laser posterior capsulotomy in patients with open‐angle glaucoma and non‐proliferative diabetic retinopathy

Aims/Purpose: The purpose of this study was to evaluate the results of the Visual Acuity Test, Autorefractometry, Pneumotonometry, Bio‐ophthalmoscopy, B‐scanning after the YAG laser Posterior Capsulotomy in patients with Open‐Angle Glaucoma and Non‐proliferative Diabetic Retinopathy.Methods: A Retrospective Cohort Study was conducted in 45 patients with OAG and NPDR. After the standard ophthalmological examination, the patients were divided into 2 groups: group 1 included 26 patients (18 women and 8 men) with OAG, average age was 68.4 ± 5 years, group 2 included 19 patients (12 men and 7 women) with NPDP, the average age was 73.8 ± 4 years. Taking into account the international protocol, all patients underwent laser capsulotomy of the posterior capsule using an Ocular Abraham Capsulotomy Lens. In patients of the first group, laser capsulotomy was performed with a power of 2‐3 mJ, laser hole – 2 mm, in patients of the second group – with a power of 1‐1.5 mJ, laser hole – 2 mm.Results: After the Laser Capsulotomy in patients of the first group there was a significant positive change in Visual Field Test: increased from 0.44 to 0.97 and in patients of the second group increased from 0.33 to 0.62. At the same time, the level of IOP remained stable: in patients of the first group before laser capsulotomy, the IOP was 19.9 ± 2.4 mm Hg, after surgery – 20.3 ± 2.4 mm Hg., in patients of the second group before laser surgery – 17.2 ± 1.4 mm Hg., after laser surgery ‐17.8 ± 2.7 mm Hg.Conclusions: After the laser capsulotomy, in the patients of the group 1 with OAG (26 patients), visual acuity significantly increased by 53.2%, in the group 2 (19 patients) – by 45.4%. The IOP level and B‐scanning results after the laser capsulotomy practically did not change and remained stable. It has been established that a personalized approach to laser capsulotomy allows one to avoid a number of complications at different stages of the operation and in the postoperative period.
