Effects of Nd: YAG Laser Capsulotomy on Visual Acuity, Central Macular Thickness, Intraocular Pressure and Refraction in Patients with Diabetes Mellitus

Abstract

Objective: It was aimed to evaluate the effects of Nd:YAG laser posterior capsulotomy (YAG PC) on best-corrected visual acuity (BCVA), central macular thickness (CMT), intraocular pressure (IOP), and refraction in patients with diabetes mellitus (DM).
 Materials and Methods: Patients who underwent YAG PC due to posterior capsular opacification (PCO) were included in this retrospective study. BCVA, refraction examination results, IOP, and CMT of the patients were evaluated. All cases were examined before laser, the day after laser, and 1 month after. 
 Results: 56 eyes of 48 patients (diabetic group) and 61 eyes of 50 patients (non-diabetic group) were included in the study. In the diabetic group, a significant increase was observed between pre-laser BCVA and the 1st-day and 1st-month BCVAs. Similarly, a significant increase was observed on the 1st-day and 1st-month CMT compared to the pre-laser CMT. A significant increase was observed in the non-diabetic group between pre-laser BCVA and the 1st-day and 1st-month BCVAs. On the other hand, no significant increase was observed on the 1st-day and 1st-month CMT compared to the pre-laser CMT.
 Conclusion: Although CMT has increased in patients with DM after YAG PC, applied for PCO treatment, this increase did not affect the visual recovery.
