Objectives: To evaluate functional and anatomical changes in macular region after Nd:YAG capsulotomy.
Background: Optical coherence tomography (OCT) enables to visualize, compare and evaluate macular region of retina.
Method: 36 patients, 17 men and 19 women (40 eyes) with posterior capsule opacification underwent Nd:YAG capsulotomy. Average age was 78.2 ± 13 years. Day 1 after procedure and after 1 month best corrected visual acuity (BCVA), intra ocular pressure (IOP), foveal minimal thickness (FMT) and macular volume (MV) were evaluated. Diclophenacum natricum drops (Uniclophen 0.1%) for 3 weeks QID were administered.
Results: Average BCVA in day 1 was 0.71, median 0.50, after 1 month was 0.80, median 0.67. Average MFT in day 1 was 197.63 ± 10.3 μm, median 189 ± 9 μm and after 1 month was 189.63 ± 11.5 μm, median 184 ± 9 μm. Average IOP 15.41 torr, median 15 torr and after 1 month 15.72 torr, median 16 torr. Average MV in day 1 was 6.53 mm3 and after 1 month was 6.51 mm3.
Conclusion: Nd:YAG capsulotomy is safe method to remove posterior capsule opacification and improve BCVA. FMT and MV are sensitive parameters that correlate with BCVA. Changes in FMT and MV were nonsignificant.
